山口県
This annual view includes only earthquakes from 2018 for which stations associated with Yamaguchi recorded Shindo.
Data period: 1 January–31 December 2018In 2018, stations associated with Yamaguchi reported local Shindo for 25 earthquakes. The highest local level recorded that year was Shindo 3.
Observation history · 2018
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.

The context below uses the place's full available history and reference models; it is not part of the 2018 statistics.
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 prefecture.
#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.
