USGS Response to an Urban Earthquake: Northridge ’94, Open-File Report system.”2 This was illustrated in the Northridge earth-quake of in California, when the Olive View Hospital of Sylmar, California, sustained no structural damage but.

It is part of the U.S. Geological Survey’s (USGS) multi-hazards project for this volcanic and heavily faulted part of California. “The analyses in the new report can be useful in estimating the extent of potential damage and economic losses in possible future earthquakes and in preparing emergency response plans,” Hill said.

The Northridge earthquake occurred on a previously unidentified “blind” thrust fault, a fault hidden below the urban area, which didn’t break all the way through to the Earth’s surface.

Sincethe USGS and its research partners have vastly improved our scientific understanding of the subsurface structures and processes affecting. It has been known since at least (ref. 1) that sediments can amplify earthquake ground motion relative to bedrock.

For the weak ground motion accompanying small earthquakes, the amplification. The recent earthquakes in Northridge, California, and Kobe, Japan, clearly demonstrated the need for such systems, where both the response time and recovery time could have been shortened had.

The Northridge, Calif., earthquake caused widespread permanent ground deformation on the gently sloping alluvial fan surface of the San Fernando Valley. The ground cracks and distributed deformation damaged both pipelines and surface structures.

To evaluate the mechanism of soil failure, detailed subsurface investigations were conducted at four sites.The Mw = 17 January Northridge earthquake (USGS and SCEC, ) produced measurable co-seismic displacements over a large area (approximately km 2) including much of the San Fernando Valley and adjacent mountainous areas.
