Today, the Cascadia Subduction Zone remains eerily quiet. In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to ...
Studies of past earthquake traces on both the northern San Andreas Fault and the southern Cascadia subduction zone indicate a correlation in time which may be evidence that quakes on the Cascadia subduction zone may have triggered most of the major quakes on the northern San Andreas during at least the past 3,000 years or so. The evidence also ...
Scientists say that the Cascadia subduction zone off the coast of the Pacific Northwest has the potential to spark a magnitude-9.0+ earthquake, plus a subsequent tsunami. That scenario last ...
On Jan. 26, 1700, an earthquake on the Cascadia fault caused the forest to lurch downward by more than 3 feet. Soon after, a tsunami perhaps 100 feet high barreled through at 20 or 30 mph.
[1] [2] The stated mission of the center [3] is to (i) carry out basic and applied science research on earthquake hazards at the Cascadia Subduction Zone, (ii) promote access to careers in the geosciences, especially amongst minoritized individuals, and (iii) form partnerships between researchers and organizations in charge of response and ...
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. The plate slipped an average of 20 meters (66 ...
A hole in a 600-mile-long fault line has been discovered at the bottom of the Pacific ocean - and it could be the trigger of a magnitude-9 earthquake on the US coast. Just outside of Oregon ...
Analysis of measurements led to the successful prediction of ETS events in following years (e.g., 2003, 2004, 2005, and 2007). In Cascadia, these events are marked by about two weeks of 1 to 10 Hz seismic trembling and non-earthquake ("aseismic") slip on the plate boundary equivalent to a magnitude 7 earthquake. (Tremor is a weak seismological ...
