App Description
All you need, in one app
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.

② Push Notifications for Important Information

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 n
