If several earthquakes reached the same highest local Shindo, we show the most recent one. Monthly counts depend on station coverage and imported records; they do not establish a seasonal pattern or predict the next earthquake.
Observation history · 2022
This history counts earthquakes observed at stations in the place, not earthquakes whose epicentre lies inside its boundary. Counts can change as stations are updated and older or corrected observations are added.

Earthquake 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.
