Earthquake scenarios affecting this place

Official J-SHIS models ranked for their potential impact on this municipality.

J-SHIS / NIED

#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.
