J-SHIS / NIEDGround conditions near an observation station
J-SHIS data for the 250 m mesh containing 唐津市西城内.
How to read these values
A landform class assigned to the whole 250 m mesh and used to estimate AVS30. The name alone does not determine safety, and it is model data rather than a borehole survey at the station.
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 85% 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.

J-SHIS / NIEDEarthquake 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.
