GROUND MOTION ESTIMATION Software for: Automatic processing & graphic rendering of spatial distribution of earthquake induced ground shaking in different formats Information dissemination & displayed via Webpages Antelope module provided by Kinemetrics allows for near real-time data acquisition and interface with USGS ShakeMap program 25
GROUND MOTION ESTIMATION Why ShakeMap? Location & magnitude alone not adequate to determine possible areas of damage ShakeMap incorporates attenuation relations, geologic data, and recorded data Provides easy-to-digest visuals showing areas of peak ground motion (PGV, PGA, PSA) for nonseismologists The defacto standard 26
GROUND MOTION ESTIMATION ShakeMap Automation within Antelope Antelope real-time system will calculate locations and magnitudes Antelope downloads segmented strong-motion data automatically and measures ground-motion metrics for available weak- and strong-motion sites Starting the ShakeMap system for a suitable origin 27
GROUND MOTION ESTIMATION ShakeMap Results 28
