J-SHIS / NIEDGround conditions near an observation station
J-SHIS data for the 250 m mesh containing 伊賀市緑ケ丘本町.
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 14% 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.

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.
