2010 Haiti EarthquakeThis USArray wave visualization shows the actual seismic data collected during the January 12, 2010 magnitude 7.0 earthquake in Haiti. Even though this earthquake did not occur in the United States, data collected during this earthquake by USArray seismometers was used to map the motion of the plate boundaries near Haiti.
The station circle changes color depending on whether the seismometer is moving up or down. Blue is up, red is down. The more intense the color, the larger the motion.
