Akkeshi Town earthquake and Shindo history in 2018
厚岸町
This annual view includes only earthquakes from 2018 for which stations associated with Akkeshi Town recorded Shindo.
Data period: 1 January–31 December 2018In 2018, stations associated with Akkeshi Town reported local Shindo for 14 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.

Ground & J-SHIS
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.
Ground conditions near an observation station
J-SHIS data for the 250 m mesh containing 厚岸町尾幌.
How to read these values
The average speed of an S-wave through the upper 30 metres. A lower value generally indicates softer material that can amplify shaking more. J-SHIS uses this value to estimate the amplification shown to the right. It is not predicted Shindo.
For the same incoming wave, local ground conditions may make peak-motion velocity at the surface about 30% higher than at engineering bedrock (Vs = 400 m/s). This value describes motion velocity—it does not multiply magnitude or forecast ground acceleration.
Ground conditions can change over short distances. These values do not rate the whole place or the safety of a building, and they cannot predict an earthquake. Source: J-SHIS (NIED), V4 model; processed for presentation by JISHINDESU.
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.
