The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca plate from mid- Vancouver Island , south along the Pacific Northwest coast as far as northern California .

2024年6月16日 · Scientists now know the 700-mile fault called the Cascadia Subduction Zone, 100 miles off the coast of Northern California stretching north to Vancouver Island, could trigger a 9.0 magnitude...

2024年6月7日 · A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.

FEMA’s Region 10 Cascadia Subduction Zone (CSZ) Earthquake and Tsunami Plan 2022 lists the following regarding a full-margin rupture: 27 counties, including areas impacted along the Pacific Coast, Puget Sound, and Columbia River

The 1700 tsunami that impacted the Puget sound region was triggered by a megathrust earthquake off the coast of northern California, Oregon, Washington, and British Columbia on the so-called Cascadia margin.

On this date, a tsunami flooded the shores of Japan. There was no earthquake or other warning, and it would be almost 300 years before scientists and historians identified the source of this "orphan tsunami" as an estimated magnitude 9.0 Cascadia subduction zone earthquake.

2020年6月22日 · The Cascadia subduction zone (CSZ) is an exceptional geologic environment for recording evidence of land level changes, tsunamis, and ground motion that reveals at least 19 great megathrust earthquakes over the past 10 kyr.

Oregon has the potential for a 9.0+ magnitude earthquake caused by the Cascadia Subduction Zone and a resulting tsunami of up to 100 feet in height that will impact the coastal area.

2024年5月30日 · The Cascadia Subduction Zone, which stretches from northern California to southern British Columbia, is known for its potential to produce powerful earthquakes and tsunamis. The 1700 event caused significant coastal subsidence—over a meter in some areas—and generated a massive tsunami in the Pacific Ocean that reached as far as Japan.

2016年1月21日 · Tsunami generated by a ~9.2 magnitude Cascadia earthquake in 1700 along a ~600 mile long fault from Vancouver Island, British Columbia to northern California. A tsunami is a series of waves, not just a single wave.
