  2. Cascadia subduction zone - Wikipedia

    en.wikipedia.org/wiki/Cascadia_subduction_zone

    Megathrust earthquakes are the most powerful earthquakes known to occur, and can exceed magnitude 9.0, which releases 1,000 times more energy than magnitude 7.0 and 1 million times more energy than a magnitude 5.0. [18] [19] [20] They occur when enough energy (stress) has accumulated in the "locked" zone of the fault to cause a rupture. The ...

  3. Megathrust earthquake - Wikipedia

    en.wikipedia.org/wiki/Megathrust_earthquake

    The thrust faults responsible for megathrust earthquakes often lie at the bottom of oceanic trenches; in such cases, the earthquakes can abruptly displace the sea floor over a large area. As a result, megathrust earthquakes often generate tsunamis that are considerably more destructive than the earthquakes themselves.

  6. Mendocino triple junction - Wikipedia

    en.wikipedia.org/wiki/Mendocino_Triple_Junction

    The Cascadia subduction zone is capable of producing megathrust earthquakes on the order of MW 9.0. Due to the relative plate motions, the triple junction has been migrating northwards for the past 25–30 million years, and assuming rigid plates, the geometry requires that a void, called slab window , develop southeast of the MTJ.

  9. San Andreas Fault - Wikipedia

    en.wikipedia.org/wiki/San_Andreas_Fault

    Seismologists discovered that the San Andreas Fault near Parkfield in central California consistently produces a magnitude 6.0 earthquake approximately once every 22 years. Following recorded seismic events in 1857, 1881, 1901, 1922, 1934, and 1966, scientists predicted that another earthquake should occur in Parkfield in 1993.
