Hazardon

Hazardon is a Japan-focused disaster prevention Chrome extension that helps you stay informed by pulling information from local governments. It displays evacuation shelter and site locations, allows you to view 7 hazard map types (landslide, tsunami risk area, and more), and shows rainfall radar as well as real-time risk maps. The extension also supports entry requests to evacuation shelters and links with Q-ANPI and local government announcements.

Push notifications from local governments alert you to weather warnings, earthquakes, landslides, and evacuation or civil protection information in your registered municipalities. A live map of your area shows shelter open/closed status, crowd conditions, road closures, and hazard details, with multilingual support (13 languages). An internet connection is required to receive map data and notifications.
