The Caltech Seismological Laboratory is an arm of the Division of Geological and Planetary Sciences of the California Institute of Technology. Known as "the Seismo Lab", it has been a world center for seismology research since the 1920s, and was for many decades a go-to source for rapid (and quotable) commentary to the press on large earthquakes.
San Andreas Fault. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific Plate and the North American Plate. Traditionally, for scientific purposes, the fault has been ...
California Institute of Technology. Kate Hutton, nicknamed the Earthquake Lady, Dr. Kate, or Earthquake Kate, is a former staff seismologist at the California Institute of Technology in Pasadena, California, where she monitored Southern California's earthquake activity for 37 years. [1]
Saturday's event was the sixth earthquake of magnitude 3 or higher since a magnitude 4.7 earthquake in the same area was widely felt across Southern California on Sept. 12.
September 12, 2024 at 12:49 PM. USGS. A magnitude 4.7 earthquake has been detected in California’s Ventura County, according to the United States Geological Survey. The earthquake, which struck ...
Thomas H. (Tom) Heaton is an American seismologist, known for his influential contributions in earthquake source physics and earthquake early warning. Currently he is the professor of geophysics and civil engineering at California Institute of Technology (Caltech) and one of the world’s leading experts on seismology.
Map showing the relative location of the 1999 Hector Mine Earthquake and its foreshocks. This strike-slip earthquake occurred in a remote part of the Mojave Desert, 47 miles (76 km) east-southeast of Barstow, California, inside the Twentynine Palms Marine Corps Base. Strike-slip faults are fractures where the blocks have mostly moved horizontally.
Southern California lies at the southern end of this block, where the Southern California faults create a complex and even chaotic landscape of seismic activity. Seismic, geologic, and other data has been integrated by the Southern California Earthquake Center to produce the Community Fault Model (CFM) database that documents over 140 faults in ...
