Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand-alone articles. The principles described also apply to lists. In summary, only damaging, injurious, or deadly events should be recorded.
Damage to a masonry building (Cadillac Hotel) in Seattle, from the 2001 Nisqually earthquake. Other recent work [34] indicates that the Seattle Fault can generate two types of earthquakes; both pose "considerable hazard" to the Seattle metropolitan region. The A.D. 900–930 earthquake is believed to be the only instance in the past 7,000 years ...
Named after the Nisqually Delta, this earthquake hit the southern end of Puget Sound causing damage to the ports of Seattle and Tacoma. [19] [8] In the month following the earthquake, the National Oceanic and Atmospheric Administration and the USGS assembled a team to map the bathymetry of the deltas near the epicenter.
Damaging earthquakes are well known in the Pacific Northwest, including several larger than magnitude 7, most notably the M9 1700 Cascadia earthquake and the M7.0–7.3 earthquake in about 900AD on the Seattle Fault. The M6.5 1965 Puget Sound earthquake shook the Seattle, Washington, area, causing substantial damage and seven deaths. This event ...
The 1965 Puget Sound earthquake occurred at 08:28 AM PDT (15:28 UTC) on April 29 within the Puget Sound region of Washington state. It had a magnitude of 6.7 on the moment magnitude scale and a maximum perceived intensity of VIII ( Severe ) on the Mercalli intensity scale .
The Lake Washington sunken forests were both a part of the scientific discovery of a major fault line under Seattle, Washington, and part of a timber piracy case in the late 20th century. In a precedent-setting case, the Washington State Supreme Court decided that ancient drowned forests are state property and not eligible for salvage.
That envisions a magnitude 7.8 earthquake that could result in 1,800 deaths and nearly 50,000 injuries — the deadliest quake in modern Southern California history. More than 1,000 of those ...
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.
