日本地震情報 is a free Android app developed by iMobSoft. It falls under the Lifestyle category, specifically the Weather subcategory. This app provides a comprehensive list of current and past earthquake information in Japan.

The earthquake list is color-coded for easy identification. Red markers indicate earthquakes with a maximum intensity of 5 or higher, gold markers represent earthquakes with a maximum intensity between 5 and 3, and green markers signify earthquakes with a maximum intensity of 3 or lower.

As soon as the Japan Meteorological Agency releases earthquake information, it is immediately added to the list. Tapping on an entry in the list displays detailed earthquake information. Users can also view the epicenter of the earthquake on a map by tapping the "地図へ" (Show on Map) button.

This app also provides explanations about the difference between magnitude and seismic intensity, helping users understand the scale and impact of earthquakes. Magnitude (M) is used to express the energy released by seismic waves, while seismic intensity measures the level of shaking at a specific location.

With its real-time earthquake information and user-friendly interface, 日本地震情報 is a valuable tool for those living in or visiting Japan.
