Stations and strongest local observations
The map combines stations assigned to this place with earthquakes that produced its strongest local readings.
Observation history
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.
Observed events by year
Choose a year to update the event history and local Shindo distribution.
Shindo observed in this place
The highest reading from stations in this place, not the maximum Shindo of the whole event.

Ground & J-SHIS
A change in the number of observations cannot by itself predict a larger earthquake.
Where the shaking usually comes from
Source regions of earthquakes observed here, ordered by the number of reports.

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.
