  2. Puget Sound faults - Wikipedia

    en.wikipedia.org/wiki/Puget_Sound_faults

    The San Juan Island and Leach River faults crossing the southern end of Vancouver Island are significant and undoubtedly connected with the Darrington—Devils Mountain and Southern Whidbey Island faults, and certainly of particular interest to the residents of Victoria, B.C. But their significance to the Puget Sound area is unknown.

  3. Cascadia subduction zone - Wikipedia

    en.wikipedia.org/wiki/Cascadia_subduction_zone

    The magnitude of a megathrust earthquake is proportional to length of the rupture along the fault. The Cascadia subduction zone, which forms the boundary between the Juan de Fuca and North American plates, is a very long sloping fault that stretches from mid-Vancouver Island to Northern California. [18]

  5. Kermadec–Tonga subduction zone - Wikipedia

    en.wikipedia.org/wiki/Kermadec–Tonga_subduction...

    A number of microplates exist between the two major plates and host various back-arc structures of which the largest are the volcanic Tonga–Kermadec Ridge, the actively spreading Lau Basin and the Havre Trough. At the southern end there is a transition to the transform faults of the South Island of New Zealand.

  6. Leech River Fault - Wikipedia

    en.wikipedia.org/wiki/Leech_River_Fault

    The Leech River Fault (LRF) extends off-shore towards Cape Flattery, where the Crescent—Pacific Rim contact continues northwest as the Tofino Fault (TF). [6] The bottom contact of the Crescent Terrane has been uplifted and exposed along the edge of the Olympic Peninsula, where it is known as the Hurricane Ridge Fault (HRF).

  7. Seattle Fault - Wikipedia

    en.wikipedia.org/wiki/Seattle_Fault

    The Seattle Fault was first recognized as a significant seismic hazard in 1992, when a set of reports showed that about 1,100 years ago it was the scene of a major earthquake of about magnitude 7 – an event that entered Native American oral traditions. Extensive research has since shown the Seattle Fault to be part of a regional system of faults.

  8. Queen Charlotte Fault - Wikipedia

    en.wikipedia.org/wiki/Queen_Charlotte_Fault

    Tectonic map of Alaska and northwestern Canada showing main faults and historic earthquakes. The Queen Charlotte Fault is an active transform fault that marks the boundary of the North American plate and the Pacific plate. [1] [2] It is Canada's right-lateral strike-slip equivalent to the San Andreas Fault to the south in California. [3]

The Ring of Fire (also known as the Pacific Ring of Fire, the Rim of Fire, the Girdle of Fire or the Circum-Pacific belt) [note 1] is a tectonic belt of volcanoes and earthquakes.
