UNDERSTAND EACH EARTHQUAKE • Epicenter, magnitude, maximum Shindo, depth and tsunami information • A map and list of JMA station observations • Distance from your saved places and the nearest confirmed reading • Notifications when a confirmed report matches your place settings

EXPLORE HISTORY AND LOCAL DATA • Search and filter earthquake history by period, Shindo and magnitude • Browse confirmed histories for Japan’s prefectures and municipalities • Explore yearly activity, Shindo distribution, source regions and stations • View ground context where data is available

Earthquake information is independently organized from public data supplied by the Japan Meteorological Agency (JMA) and P2PQuake.

JISHINDESU is not an official service of JMA or any government authority. It does not provide Earthquake Early Warning (EEW) or earthquake prediction. Reports may be delayed, incomplete or corrected later. For safety-critical decisions, always check the latest information from JMA, local authorities and other official sources.
