    en.wikipedia.org/wiki/Puget_Sound_faults

    The Little River Fault (see the QFFDB, Fault 556) is representative of an extensive zone of faults along the north side of the Olympic Peninsula and in the Strait of Juan de Fuca (likely connected with the fault systems at the south end of Vancouver Island, see fault database map), but these lie west of the crustal blocks that underlie the ...

    en.wikipedia.org/wiki/Cascadia_subduction_zone

    The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 100–200 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States.

    Today, the eastern boundary of the Tonga plate is one of the fastest subduction zones, with a rate up to 24 cm/year (9.4 in/year). [1] The trench formed between the Kermadec–Tonga and Pacific plates is also home to the second deepest trench in the world, at about 10,800 m, [2] as well as the longest chain of submerged volcanoes.

    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]

    Map of the Chile Rise and its fracture zones in Nazca and the Antarctic plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown of south-west Pacific and north Pacific Ocean floors may have been characterised.

    To the northwest of the triple junction the Pacific plate currently has 15 degrees of oblique convergence, passing under the North American plate along the Queen Charlotte transform fault zone. [3] The Explorer plate is a small chunk of the Juan de Fuca plate that broke away from the Juan de Fuca plate about 3.5 Ma and has moved much slower ...
