In California, tsunami hazard areas stretch from Crescent City to San Diego. The current maps are drawn with boundaries from the California Geological Survey. The hazard zones are highlighted in ...
Here are maps showing some of Northern California’s most populated areas within a tsunami hazard zone, as determined by the California Geological Survey. The yellow section indicates the tsunami ...
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
Among the earliest records of a tsunami in California is an event in 1812 when a large earthquake in the Santa Barbara area “was followed by a tsunami that wiped out many coastal villages and ...
Estimates predict a multi-segment rupture of the fault zone is capable of producing an earthquake of magnitude 7.6–7.9. [6] [3] An earthquake this large in such close proximity to densely-populated southern California would be devastating. [7] In 1986, a M s 5.8 earthquake struck off the coast of Oceanside, killing 1 and injuring 29 more.
The Rose Canyon Fault Zone can produce large earthquakes which can be very destructive due to its proximity to major population centers in Southern California. [8] On the fault, earthquakes nearing magnitude 7 have a recurrence interval between 700±400 [ 24 ] and 2,000 years. [ 23 ]
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.
The 2015 Uniform California Earthquake Rupture Forecast, Version 3, or UCERF3, is the latest official earthquake rupture forecast (ERF) for the state of California, superseding UCERF2. It provides authoritative estimates of the likelihood and severity of potentially damaging earthquake ruptures in the long- and near-term.
