J-SHIS / NIEDEarthquake scenarios affecting this place
Official J-SHIS models ranked for their potential impact on this municipality.
#1 means the model ranks highest in the J-SHIS result for this place under the same settings. It is not a ranking of which earthquake will happen next.
Magnitude on a card describes the size of the whole earthquake model, not the Shindo expected here. Local shaking also depends on distance, depth and ground conditions.
J-SHIS 2020 model, 30-year period and Shindo 6-lower threshold. This is not a prediction of a particular earthquake. Source: J-SHIS (NIED); processed for presentation by JISHINDESU.
