Earthquake shaking — Finding the "hot spots"

Abstract

A new Southern California Earthquake Center study has quantified how local geologic conditions affect the shaking experienced in an earthquake. The important geologic factors at a site are softness of the rock or soil near the surface and thickness of the sediments above hard bedrock. Even when these 'site effects' are taken into account, however, each earthquake exhibits unique 'hotspots' of anomalously strong shaking. Better predictions of strong ground shaking will therefore require additional geologic data and more comprehensive computer simulations of individual earthquakes.

Global Fiducials Library

Introduction The Earth changes continuously in response to natural processes and human activity. The collection and interpretation of time-series imagery enhances our ability to observe and monitor Earth’s dynamic processes as well as study and understand the rapidly changing surface of our planet. The Global Fiducials Library (GFL) provides repeated satellite imagery of selected locations around the world to help scientists observe, document, and better understand those changes over time.
