Muroran City earthquake and Shindo history in 2022
室蘭市
This annual view includes only earthquakes from 2022 for which stations associated with Muroran City recorded Shindo.
Data period: 1 January–31 December 2022In 2022, stations associated with Muroran City reported local Shindo for 13 earthquakes. The highest local level recorded that year was Shindo 3.
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.

Ground & J-SHIS
The context below uses the place's full available history and reference models; it is not part of the 2022 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 室蘭市山手町.
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 11% lower 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.
