About NERV Disaster Prevention

The NERV Disaster Prevention App is a smartphone service that delivers earthquake, tsunami, volcanic eruption and emergency warnings, as well as provides weather-related disaster prevention information for flooding and landslides, optimised based on the user's current and registered locations.

The app was developed to help people living in or visiting an area where damage is expected to occur, to accurately assess the situation and make quick decisions and actions.

With information received directly through a leased line connected to the Japan Meteorological Agency, our proprietary technology enables the fastest information distribution in Japan.


▼ All the information you need, in one app

Get a wide range of disaster prevention information, including weather and typhoon forecasts, rain radar, earthquake, tsunami and volcanic eruption alerts, emergency weather warnings and landslide information, river information, and heavy rain risk notifications.

By interacting with the map on the screen, you can zoom in on your location or pan across the country and see the cloud cover, typhoon forecast areas, tsunami warning areas, or the scale and intensity of an earthquake.


① Providing users with the most appropriate disaster information

The home screen displays the information you need at the time and place you need it. When there’s an earthquake, the home screen will show you the latest information. If another type of warning or alert is issued while the earthquake is active, the app will sort them depending on the type, elapsed time and urgency, so you’ll always have the most important information at your fingertips.


② Push Notifications for Important Information

We send out different types of notifications depending on the device’s location, the type of information and level of urgency. If the information is not urgent, we send a silent notification as not to disturb the user. For more urgent situations where a disaster is time-sensitive, a ‘Critical Alert’ alerts the user to an imminent danger. Notifications like Earthquake Early Warnings (Alert level) and Tsunami Warnings will be forced to sound, even if the device is in Silent or Do Not Disturb modes.

Note: Critical Alerts will only be sent to users in the target area of the most urgent types of disasters. Users who have registered their location but are not in the target area will instead receive a normal notification.

※ In order to receive Critical Alerts, you need to set your location permissions to “Always Allow” and have Background App Refresh turned on. If you don’t want Critical Alerts, you can disable them from Settings.


③ Barrier-Free Design

We paid close attention when designing the app to ensure our information is accessible to everyone. We put a focus on accessibility, with colour schemes that are easy to distinguish for people with colour blindness, and use a font with large, clear letters so long bodies of text are easy to read.


▼ Supporters’ Club (In-App Purchase)

In order to keep doing what we do, we’re looking for supporters to help us cover the development and operational costs of the app. The Supporters’ Club is a voluntary membership scheme for those who want to give back to the NERV Disaster Prevention app, by contributing to its development with a monthly fee.

You can find out more information about the Supporters’ Club on our website.

最新版本5.1.2更新日誌

Last updated on 2024年04月15日
歷史版本
This update features the following improvements
- Real-Time Seismic Intensity is now displayed on the Earthquake Early Warning screen by default
- Improved Real-Time information updates while viewing the Earthquake Early Warning screen
- The map on the Earthquake Early Warning screen now shows a larger area around the current location
- Improved Shaking Detection algorithm
- Improved display of Tsunami Forecast areas
- Added a retry process in the event of a network error
- Fixed English Translation of certain Tsunami Information

[Recent updates from the Development Team]
We extend our heartfelt condolences to those affected by the Noto Peninsula Earthquake that occurred at the beginning of this year. We also solemnly remember those who lost their lives.

During the Noto Peninsula Earthquake, we weren't satisfied with the performance of our push notification delivery infrastructure, so we tripled the number of instances and quadrupled the memory allocation to each, ensuring notifications were sent out as quickly as possible. We also identified and rectified minor issues in the Strong Motion Monitor layer and the program responsible for determining the notification range of estimated seismic intensity. Despite the unprecedented demand, our systems handled over 900 million accesses, with data transfers exceeding 4TB, at an error rate of 0%. The Strong Motion Monitor layer received a peak access of over 23,000 requests per second.

While reinforcing our infrastructure and handling traffic incurs a cost, these expenses are offset by the support of our Supporters' Club members. We sincerely appreciate your ongoing cooperation, which allows us to maintain and improve the system's reliability.

Since last year, we have been participating as committee members of the Japan Meteorological Agency's "Study Group on the Provision of Information on Long-Lasting Tsunami." However, given the tsunami warnings issued on January 1st and April 3rd of this year, there is still more work to be done to improve the quality of the information.

As we enter the new fiscal year, many of you may be embarking on new endeavours. With the changing seasons, please take care of your health.

2023年12月29日
This update fixes a few minor bugs.

■ 2023 In Review
This year, we experienced complex patterns of data processing, such as tsunamis caused by large volcanic eruptions overseas and a series of large overseas earthquakes, tsunamis caused by earthquakes near Torishima that continued without a known magnitude, and J-ALERTs in the early morning and at night.

There were many other non-development tasks as well, such as holding lectures at study groups of the Cabinet Office and the Digital Agency, and participating as a committee member in study groups of the Japan Meteorological Agency and the Ministry of Internal Affairs and Communications. It was a year in which our role was no longer limited to just developing disaster prevention applications.

This release will be the last update of the year. We want to thank you all for your support and for taking good care of the app over the past year. We will continue to update the app in the coming year to make it even more useful for everyone.

Misato Katsuragi also commented during the attack of the angels: "You don't care about our reasons, do you? You must be the type of person women hate." But you never know when a disaster or crisis will strike. We hope that you will reconfirm your disaster stockpiles and evacuation methods in various situations for the year 2024.

Please stay safe, as the year-end and New Year's holidays are also a season of accidents and fires.

・ Added "Synoptic Chart" layer to Early Access
・ The "Lightning" layer is now available to all users
・ Added Upgraded/Downgraded warning regions to the Tsunami Information screen
・ Fixed an issue where the ashfall forecast display could become distorted when the device's font size was set to large

■ Synoptic Chart Layer
New to Early Access is a brand new layer - the Synoptic Chart.
Also known as a "Weather Map", this layer provides an overview of weather patterns - displaying isobars, pressure systems, fronts, and an infrared cloud layer as observed by the Himawari meteorological satellite. Past observations are taken seven times a day (every 3 hours), and you can view forecasts for 24 and 48 hours ahead (updated twice daily).

■ Early Access
"Early Access" is a perk for NERV Disaster Prevention Supporter's Club members (paid) to access new features ahead of public release. For details, refer to the membership guide in the app's Menu tab.

■ Lightning Layer
The previously featured Lightning layer in Early Access is now available to all users. You can select it from the Layer button in the Map tab. It allows you to check the situation of cloud discharges and lightning strikes through lightning nowcast and the lightning monitoring system.

■ Recent Activities of the Development Team
・ We've been operating the NERV Disaster Response vehicles to respond to large-scale power outages and network communication issues. These vehicles were recently showcased at the Mitsubishi Motors booth at the Japan Mobility Show. It was great to see many people interested in our activities!
・ On November 9th, we held an open forum event using X's (formerly Twitter) Spaces feature with representatives from khara, TBS, and NERV. It was quite a process to get approvals from the higher-ups of each company using their official accounts, but it turned out to be quite an enjoyable event.
・ This month, we're preparing for speaking engagements at events held by the Cabinet Office, Code for Japan, and TEDxUTsukuba. We will also be serving as committee members for discussions at the Ministry of Internal Affairs and Communications. It's a ton of homework, but we haven't forgotten about preparing new app features! Please look forward to the developments.
・ Onboard food sales on the Tokaido Shinkansen have ended, and I heard ice cream is now sold through vending machines on the platforms, but I couldn't find them... I was hoping to have some ice cream on a recent trip...

We hope you continue to support our efforts and that you'll keep using the NERV Disaster Prevention app in your daily disaster mitigation efforts.

Now, on to the next update!

This update improves support for iOS 17.

Our Development Team has been hard at work to ensure there are no issues with the app in iOS 17. We've also been fine-tuning the strong-motion monitor and push notification systems, as well as making adjustments related to the River Levels layer.

We recently conducted a survey on X (formerly Twitter) that showed 72.7% of users prefer to use the Dark theme, while 27.3% prefer the Light theme. If you've been using the app without knowing you can change the theme, contrast, text size and thickness, we recommend you check out [Appearance] in the [Menu] tab.

It also appears that some users may be unaware that we launched the "Strong-Motion Monitor Layer" on September 1st. With this feature, you can see real-time tremors all over Japan. You can access it by going to the [Map] tab → [Layers] button → Strong-Motion Monitor. When enabled, real-time seismic intensity will also be displayed on the Earthquake Early Warning screen.

As we all eagerly wait for cooler weather, it's important to remember to take care of your health.

We hope you'll look forward to the next update!

・ Strong-Motion Monitor Layer is now available for all users!
・ "Radar" Tab is now the "Map" tab
- Easily change the default layer
- Long-pressing the map icon now provides a shortcut to the Layer selection menu
・ Refreshed Dark Theme Icons
・ Updated Notification Sounds

To use the Strong-Motion Monitor Layer, select the Map tab → Layers → Strong-Motion Monitor.

◆ "To communicate even a second earlier."
Today is the 100th anniversary of the Great Kanto Earthquake that occurred on September 1st, 1923. At the time, little information was available to the public to use in disaster management. However, 100 years later, we're able to provide a countdown of expected seismic intensity and an estimated time of arrival tailored to each user based on their location, as well as real-time observed seismic intensity, updated every second.

We've been working for years to strengthen our information delivery infrastructure and speed up our apps to deliver information as quickly as possible. We are very pleased to provide new information "every second" with this update.

The information delivery infrastructure and applications we have implemented are just the beginning of this technology. The provision of such advanced seismic information has a long history of legislative, administrative, and research and development efforts, and is the result of the continuous efforts of our predecessors. This technology will only continue to improve in the future.

We, too, are committed to leaving a better disaster information system for the next generation.

We hope you'll continue to support our efforts, and that you'll keep using the NERV Disaster Prevention app in your daily disaster mitigation efforts.

Now, on to the next update!

・ Added "Strong-Motion Monitor" layer to Early Access

What is "Strong-Motion Monitor"?
The Strong-Motion Monitor layer is a feature that displays real-time Seismic Intensity across Japan, based on the Seismic Observation Network operated by the National Research Institute for Earth Science and Disaster Resilience (NIED).

When an earthquake occurs, you can observe the real-time propagation of the earthquake through the colour changes displayed by each station. When changes occur at several observation stations, the screen automatically zooms to the affected area, and highlights the stations based on a grid. When all of the grid squares are gone, the screen returns to show the whole country.

When an Earthquake Early Warning (Forecast) is issued, the Strong-Motion Monitor layer automatically integrates and displays the information from the EEW, including the forecasted Seismic Intensity distribution, and propagation of the P and S waves alongside the Strong-Motion data.

A guide will be displayed the first time you use the Strong-Motion Monitor layer, so please read it carefully before using the feature.

The Strong-Motion Monitor layer has been experimentally developed since February 2023 based on the "Joint Research Implementation Plan for the Utilisation of Strong-Motion Monitor Data", which was established by four parties: the National Research Institute for Earth Science and Disaster Resilience (NIED), Gehirn Inc., TBS Television Inc., and TBS・JNN NEWS DIG LLC, on December 21st, 2022.

Due to the real-time nature of Seismic Intensity data being updated every second, we aim to test the service's durability against sudden increases in access during earthquake events, and verify the service's stability with a limited number of users during this Early Access period. We plan to release the Strong-Motion Monitor Layer to all users from September 1st, 2023.

Please note that this is a separate service from the "Strong-Motion Monitor" web service provided by NIED. Gehirn Inc. has a dedicated communications line installed at NIED for information processing and distribution for the NERV Disaster Prevention app in order to provide this service.

"Early Access" is a paid benefit for NERV Disaster Prevention Supporters' Club members to use new features in advance. For more information, please refer to the enrollment guide in the app's "Menu" tab.

2023年07月07日
- Flood Forecasts for designated rivers have been added
- Fixed a problem where water level observation points overlapping your current location could not be selected

The JMA, MLIT and prefectural governments jointly issue designated river flood forecasts as a public service to keep residents informed on river conditions near them. The four levels of flood information associated with a forecast are Flood Alert (equivalent to Warning Level 2), Flood Warning (equiv. Level 3), High Risk of Flooding (equiv. Level 4) and Floods Occurring (equiv. Level 5).

This update also adds push notifications for when a designated river flood forecast is issued. You can now also see the forecast water level in the height graph when you tap on a station.

We still have more features coming for landslide and flood information in the future, so we greatly appreciate your support as we continue to work on them.
4.4.1
2023年06月06日
This update fixes a bug where the river layer may appear underneath certain map features.

The release of "River Water Level Information" on June 2nd coincided with many rivers exceeding the emergency flood level shortly after release, and our systems sent numerous push notifications to users. We spent the day monitoring API errors and ensuring the reliability of the system.

Even in Chiyoda-ku (where our office is located), the nearby Kanda River experienced an increase in water level due to heavy rain, so on the very first day of release, we personally received notifications from the app indicating that the flood levels had been exceeded. As users of the app ourselves, we were able to make use of the water level information.

We managed to release the update just in time within a tight schedule and were fully dedicated to delivering information without issue. However, there were some areas where adjustments were insufficient, and this update addresses those issues.

As we enter the rainy season, we hope you'll make use of our push notifications and the new river water level information layer to stay safe.

We will continue to work on further enhancing the delivery of Disaster Prevention information and would be grateful for your ongoing support.

2023年06月02日
Added a new River Water Level feature

In this update, we've added a new 'River' layer. With the River layer, you can check the water levels at the monitoring stations and risk management-type water level gauges, updated every 10 minutes.

- Display Method
You can access this by selecting the 'River' layer from the layer switching button on the 'Radar' tab. It overlays water level information on the flood damage layer of the risk distribution.

- Supports Push Notifications
We will promptly notify you via push notifications if the water level at a nearby monitoring station exceeds the flood risk level in your current or registered location. Monitoring stations with water levels above the warning level are also displayed on the home tab.

- About Flood Risk Water Level
The flood risk water level is a guide for issuing evacuation instructions. If the water level at a nearby monitoring station reaches the flood risk level, please ensure your safety by making your own judgment, without waiting for evacuation instructions from local government.

To our supporter members
We truly appreciate your consistent support.
Acquiring river water level data is an extremely high-cost endeavor, which has increased our operating costs by nearly 3 million yen annually. The ability to purchase such data has been made possible thanks to our supporting members. Moreover, the acquired data cannot be utilized in its original form, requiring us to organize and process it for ease of use. This necessitated considerable time and effort in preparation for this release, and we faced numerous challenges along the way. With a forecast of heavy rain, our development team worked at a breakneck pace to finalize the implementation for release.
Now that we've finally released this feature, we sincerely hope you will make good use of it in the coming rainy season, and regularly check the river conditions.

As it's the rainy season, please not only take care against weather disasters but also food poisoning. We wish you all safety and good health.

- Fixed an issue where past Earthquake Early Warnings were displayed when you opened the app
- Fixed an issue where the countdown on the Earthquake Early Warning screen could stop under certain conditions
- Fixed an issue where an error could occur when opening the earthquake information screen
- Adjusted the Lightning screen colours in the light theme

Since the earthquakes that occurred in the Noto region on May 5th during Golden Week, we've been adjusting the processing and delivery conditions of our earthquake alert algorithm in accordance with the seismic activity situation.

Each time a major earthquake occurs, we check our delivery network, the earthquake information and estimated seismic intensity distribution processing system - to ensure that there are no issues - and strengthen our push notification delivery server, identify any problems that occur in the app, and provide lifeline information via Twitter to inform those who need it.

We'll continue to improve our app and our systems for speed and reliability, and we hope you'll continue to support using the NERV Disaster Prevention app.

2023年02月01日
This update includes:
- Enhanced Earthquake Early Warning functionality
- Higher resolution Estimated Seismic Intensity Distribution map
- Fixed an issue with the Accessible Themes settings page

From the 1st of February, the JMA has added "Long-Period Ground Motion" information to the announcement criteria for Earthquake Early Warnings issued by the JMA. Long-Period Ground Motion refers to the slower, longer waves produced by an earthquake that can cause the upper floors of high-rise buildings to shake/sway more strongly. This update adds support for Long-Period Ground Motion forecasts in line with the updated requirements and displays alongside the earthquake early warning when long-period ground motion is expected to occur.

Other improvements include support for higher resolution estimated seismic intensity distribution data, seismic intensity calculation using the PLUM method, and the ability to display multiple earthquake early warnings when issued simultaneously.

The JMA has been introducing a series of earthquake-related improvements, and the NERV Disaster Prevention development team has been working hard to bring these improvements to users as quickly as possible.

The development team plans to continue to update earthquake-related information and enhance the app's functionality for the upcoming rainy season.

We hope you continue to make use of the NERV Disaster Prevention app.

In this update, we've improved support for J-Alert.
- Added support for English J-Alert notifications
- J-Alert notifications are now displayed on the home screen and timeline. Tap on the notification to view the warning area on the map
- Fixed display issues
- English translation fixes

J-Alerts used to be provided only as notifications, but now information can be viewed from Home and Timeline, in addition to notifications.

Following North Korea's missile launch on October 4th, the Government used the National Instantaneous Warning System (J-Alert) to send out information for the first time in five years (since 2017). The development team was initially surprised, wondering if there had been a system issue or a bug. However, after checking the data and watching the event unfold on TV, they realised it was not a mistake. Since then, missiles have been launched one after another, and the development team began preparing to enhance the app's J-Alert functionality by the end of the year.

We want to thank you for your continued use of the app. This release will be the last update before the end of the year. We will continue to update the app in 2023 to make it even more helpful for everyone.

The year-end and New Year's holidays are also when accidents and fires occur more commonly. We hope you all have a safe holiday season.

The NERV Disaster Prevention app now supports widgets on the lock screen. See your location's current weather and temperature, weather warnings and advisories, sunrise and sunset times, and the day's min/max temperatures at a glance, without having to open the app!

Please note that Lock Screen Widgets only display information for your current location.

To our Supporters' Club members;
Our development team is able to conduct research and implement new features like these, thanks only to your support. The features we've been working on would not have been possible without your generosity. With each new feature or service that we add, our financial burden only increases. However, for the safety of everyone in Japan, we know that features and services like these are crucial in helping you to get the information you need, as soon as possible.

We're grateful for your continued support.

Choose a colour scheme to suit your colour vision, a contrast to suit visual sensitivity and low vision, text size and thickness to suit visual acuity and field of vision, and a layout optimised for screen readers.

We've received many requests about the display of the app, and the development team's been working hard for over 11 months to improve it. We've redesigned the colour scheme of every screen in the app, as well as re-implemented the map system, widgets and all other internal components. We're delighted to be able to release it finally to our users.

We hope you will find it useful!
3.4.1

In this update:
- Timeline has been improved so that the Typhoon map is also displayed on the Typhoon Information screen
- Minor bug fixes and improvements
- Colour scheme of river flood forecast
- Map compass position
- River name layer order
- Fix issue with notification language not being updated when switching devices

Our next major update is expected to drop support for iOS 12. The app development team is currently in the process of preparing for this update and is steadily implementing new features. We'll keep doing our best to contribute to information accessibility.

We're able to implement these new features thanks to our support members and many users. We'd like to thank you for your ongoing support. Please continue to support us in the future.

In this update, the colour scheme of the Risk Distribution layer has been changed in line with updated JMA specifications.

Previously, the colour scheme followed: yellow (caution), red (warning), light purple (dangerous), and dark purple (very dangerous). With this update, light purple and dark purple have been merged into purple (dangerous) and a new level, black (emergency).

However, you may think that it wouldn't stand out if just the colour black were used in the NERV Disaster Prevention app, as the app's interface and maps are all black. The rationale for using black for evacuation and risk distribution information comes from the Cabinet Office's guidelines. Still, black is a poor match for our app. For this reason, we decided to use a dark purple with black stripes (or black with thick purple stripes, depending on your interpretation) to represent the "emergency" level.

As high temperatures continue day after day, we hope you're taking action to prevent the effects of heat stroke. Stay cool!

This update contains the following;
- Changed the map engine and data source
- Fixed a problem where the seismic intensity list may not be displayed when the estimated seismic intensity distribution is displayed

We've replaced the map engine with one we've developed in-house. Most users won't notice a difference, but for us, this is something we've been working on for a long time. This results in much greater accuracy of place names and topography for the end-user. This initiative is an important basis for future updates and we hope you'll continue to support us as we plan an even bigger update, coming in September.

As the rainy season has now begun, please stay safe.

This update adds Estimated Seismic Intensity Distribution!

Estimated Seismic Intensity Distribution is an area representation of seismic intensity observed by seismometers, using the ground amplification near the surface to estimate on a 1km mesh what intensities were observed, even in areas where there are no seismometers.

This is our first update in a while, as the development team has been busy with other projects over the last few months.

3.2.0
2021年12月24日
This update features:
- Short-Period Snowfall Forecast
- Lightning Distribution layer bug fixes

Thank you for using the NERV Disaster Prevention app! While in the last update we said it would be "the last update of the year", due to forecast heavy snowfall between the 25th and 28th, we rushed to release this update to introduce Short-Period Snowfall Forecasts a little earlier than we had planned.

The Short-Period Snowfall Forecast allows you to view the current snow depth and snowfall distribution estimated hourly, as well as the forecast for the next 6 hours. It's available as part of the Snow layer on the Radar screen.

The area around Japan is expected to experience heavy snowfall, mainly on the Sea of Japan-side, from Northern to Western Japan due to a strong winter pressure pattern, from the 25th to the 28th. Please be careful around this time for heavy snowfall.

The winter holiday season is the most dangerous time of year for accidents and fires, so remember to be careful around this time as we all try to stay warm during these cold winter months.
