Back in North America, in 1700, a 9.0 earthquake and monster tsunami rocked the Cascadia region, an area that stretches along what would become Western Washington, Oregon and northern California ...
The Tacoma Fault Zone marks the south end of the Seattle Uplift, of which the similar and related Seattle Fault Zone marks the north end. This uplift is believed to be either a slab of rock about 15 km thick being pushed up a ramp, or a wedge being popped up between these two faults, by tectonic forces from the south or south-west as tectonic plates riding on top of the Juan de Fuca plate are ...
(DGER [9]) One model of the Seattle Uplift: Cross-section (south to north) along the east side of central Puget Sound, looking west. TB = Tacoma Basin EPZ = East Passage Zone (Maury Island), SFZ = Seattle Fault Zone (Alki Point). Grey dots are hypocenters of earthquakes of magnitude 2 or more for 1970–2001. (Fig. 17D from Johnson & others 2004)
Puget Sound: VI: Tsunami [5] 1872-12-15: North Cascades: VIII: 6.5–7.0: scientific interest: 1700-01-26: Cascadia subduction zone: 8.7–9.2 M w Tsunami: 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 ...
The chances for a 6.0 magnitude or greater earthquake to occur along the Seattle Fault within the next 30 years is 80-85%, according to one seismologist.
According to Puget Sound Energy, which serves approximately 1.2 million electric and over 900,000 natural gas customers in the Puget Sound area, as of 11:59 p.m. local time Wednesday, they have ...
The 1949 Olympia earthquake was a damaging magnitude 6.7 intraslab earthquake that occurred at 52 km depth and caused eight deaths. Another notable intraslab earthquake in the Puget Sound region was the magnitude 6.8 2001 Nisqually earthquake. Intraslab earthquakes in Cascadia occur in areas where the subducting plate has high curvature. [13]
In southern California about 6% of M≥3.0 earthquakes are "followed by an earthquake of larger magnitude within 5 days and 10 km." [12] In central Italy 9.5% of M≥3.0 earthquakes are followed by a larger event within 48 hours and 30 km. [13] While such statistics are not satisfactory for purposes of prediction (giving ten to twenty false ...
