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.
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.
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.
We send out different types of notifications depending on the device’s location, the type of information and level of urgency.
Your exact location is never known to us; all location information is first converted to an area code used by everyone in that area (like a zip code).
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.
If the information is not urgent, we send a silent notification as not to disturb the user.
With information received directly through a leased line connected to the Japan Meteorological Agency, our proprietary technology enables the fastest information distribution in Japan.
When there’s an earthquake, the home screen will show you the latest information.
Note: Critical Alerts will only be sent to users in the target area of the most urgent types of disasters.
※ In order to receive Critical Alerts, you need to set your location permissions to “Always Allow” and have Background App Refresh turned on.
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.
The home screen displays the information you need at the time and place you need it.
We take great care not to collect excessive amounts of information about our users through this application.
