USGS Real-Time Earthquake and Plate Boundary Mapping in Google Earth™
Earthquakes happen all the time! Government agencies, such as the U.S. Geological Survey, catalog these earthquakes and provide data that can be viewed in a variety of ways, including on a Google Earth™ globe.
Follow this link and simply click on one of the KML feeds to open it in Google Earth™. The maps will display earthquakes and plate boundaries, showing the latitude and longitude of the epicenter by a dot. The dot color indicates the depth of the hypocenter, while its size represents the magnitude of the event. Watch as the earthquakes of the last week pop up as dots on the map. Even though the map shows only a week's worth of data, you can easily spot the seismic belts that delineate plate boundaries, as well as the particularly active intracratonic seismic zones. Note that at lower elevations, your map will show a grid on the Earth's surface; the grid will disappear if you zoom out to a distance of over 9,500 km.
