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.

J-SHIS / NIEDGround conditions near an observation station
J-SHIS data for the 250 m mesh containing 小笠原村父島西町.
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 44% 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.
