    It is a transform boundary that runs across Guatemala, offshore along the southern Pacific coast of Mexico, back onshore along the southernmost tip of Oaxaca, then offshore again until it merges with the Middle America Trench near Acapulco.

    It is a transform boundary that is a major branch of the San Andreas Fault. It is responsible for the formation of the Calaveras Valley. The latest earthquake was on March 30, 2009. It was a magnitude 4.3.
  • East Anatolian Fault

    San Jacinto Fault Zone
    It is considered to be the most seismically active fault zone in Southern California, contrary to popular beliefs that the infamous San Andreas Fault is the most active. It is more a series of faults focused along the same general axis. The latest earthquake was at Borrego Springs in 2010 with a magnitude of 5.4.
  • Chixoy- Polochic Fault
