Earthquake shock: Two biggest US earthquake faults ‘might be linked’
Professor Chris Goldfinger, a geologist and palaeoseismologist at Oregon State University in Corvallis, will present the findings on December 13 at a meeting of the American Geophysical Union in San Francisco.
He said: “This is mostly a circumstantial case. I don’t have a smoking gun.”
Professor Goldfinger and his team first posited in 2008 earthquakes in the southern part of Cascadia could trigger quakes on the northern San Andreas1.
The scientists reported finding layers of churned-up, sandy sediment in sea-floor cores drilled offshore.
These layers, called turbidites, usually form when earthquakes shake the sea floor, triggering underwater landslides.
