Layer: Liquefaction Hazard Overlay (ID:10)

View In: Map Viewer

Name: Liquefaction Hazard Overlay

Display Field: LiquefactionCategory

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

Liquefaction occurs when strong ground shaking, such as during an earthquake, causes loose and saturated sediments to lose strength and behave as a fluid. Liquefaction may cause ejection of liquefied material and groundwater, differential settlement of the ground surface and cracking of the ground surface associated with lateral spread. Structures founded on soils that have liquefied may experience bearing failure, differential settlement, and/or large horizontal displacements. Buoyant structures buried in liquefied soils such as tanks, pipes and manholes, may rise to the surface.

The Liquefaction Hazard Overlay indicates areas where liquefaction-induced ground damage is possible in a strong earthquake.
