Example Sentences
They are two of the West Coast’s most destructive generators of huge earthquakes: the San Andreas fault in California and the Cascadia subduction zone offshore of California’s North Coast, Oregon, Washington and British Columbia.
The authors suggest that, for thousands of years, large earthquakes on the Cascadia subduction zone were quickly followed by large earthquakes on the northern San Andreas fault.
In 1700, a Cascadia subduction zone earthquake is believed to have measured around a magnitude 9.
The study suggests the Cascadia earthquake was followed by a northern San Andreas fault earthquake from Cape Mendocino toward San Francisco, with a magnitude of around 7.9.
“What that suggests is that the San Andreas earthquake happened very closely in time after the Cascadia earthquake,” said Jason R. Patton, engineering geologist with the California Geological Survey and a co-author of the study.
