Hazardonハザードン is a free disaster prevention app designed for Android users. It provides a map that displays evacuation centers and locations, hazard maps, and notifications from local governments that use SpeeCAN Timeline/RAIDEN. The app's "Push Notification" feature sends out alerts when there are changes in the danger levels of landslides, floods, and inundation hazards, and when local governments provide updates on weather conditions, earthquakes, and hazard warnings.

The app's map feature displays the user's current location and nearby evacuation centers and locations. It also provides information on the opening/closing and congestion status of evacuation centers, as well as the hazard maps for nine different types of disasters, including landslides, tsunamis, and inundation hazards. Moreover, the app is available in 13 languages, and users can register for evacuation centers and connect with Q-ANPI and SpeeCAN RAIDEN.

It is important to note that an internet connection is required to access the app's map information, evacuation center details, and push notifications.
