Focal Mechanism

Global ShakeMovie is Princeton University's Near Real Time Global Seismicity Portal. It has been designed to present the public with near real time visualizations of recent earthquakes. These movies are the results of simulations carried out on a large computer cluster. Movies and 3D synthetic seismograms are calculated based upon the software package SPECFEM3D_GLOBE.

Earthquake movies will be available for viewing and download 1.5 to 7 hours (depending on magnitude) after receipt of notification from the Global CMT Project.

FACTS

When an earthquake occurs, seismic waves are generated which propagate away from the fault rupture.

Here we see the up-and-down velocity of the Earth's surface. Strong blue waves indicate the surface is moving rapidly downward. Strong red waves indicate rapid upward motion.

When the waves pass through soft soils (sediments) they slow down and amplify. Waves speed up when they pass through hard rock.

The color of the waves oscillates between red and blue indicating Alternating up and down motion.
