NERV Disaster Prevention is an Android app that allows users to receive notifications for disaster warnings, including earthquakes, typhoons, volcanoes, and other natural disasters, as well as emergency weather warnings and other relevant information. 

By registering your current location, the app can determine the geographical region you are in at the moment. You can zoom in on the map to get a better idea of the region, as well as its current cloud cover, wind speed, and rainfall rate. You can use the app to check the current condition of the region at the moment, as well as its predicted condition in the next 72 hours.
