A SCEC-VDO movie showing two approx. magnitude 5 earthquakes that occurred within seven days in Southern California. The second earthquake is on or near the San Andreas fault and led to concern of a much larger earthquake (that did not happen).
The Southern California Earthquake Center's Virtual Display of Objects (SCEC-VDO) is 3D visualization software that allows users to display, study and make movies of earthquakes as they occur globally. SCEC-VDO was developed by interns of SCEC Undergraduate Studies in Earthquake Information Technology (UseIT), under the supervision of Sue Perry and Tom Jordan.
