Deep Subsurface Structure (Subsurface Structure)

The map shows the 3D deep subsurface structure model down to the engineering bedrock, and to the seismic bedrock, in order to carry out the strong motion simulation. The maps show distribution of elevation and depth of the upper boundary of the each layer by color gradation.

Maps of Deep Subsurface Structure are displayed by selecting the tab "Subsurface Structure".

Example of the map of Deep Subsurface Structure

Settings

Selecting a type of map

You can select a type of map by radio buttons.

Depth : Depth of seismic bedrock or lower surface of a layer from ground surface
Elevation : Elevation of seismic bedrock or lower surface of a layer

Selecting a layer


You can select a layer to display on the map from the combobox.

Mesh Information

Zoom in the map to level of 11 or more and double-click the map. The Mesh Information window open, which shows detailed information about the mesh that you clicked and displayed as red rectangle on the map.

From left side, the graphs are arranged columnar section (see layer No. below), distribution of P-wave velocity, S-wave velocity, and density. You can change the range of depth by the "Depth" combobox.
