The fault runs roughly 600 miles off the west coast, from northern California to British Columbia, where several smaller tectonic plates are sliding under the much larger North American Plate. <strong>That subduction zone is capable of producing earthquakes with devastating destructive potential, up to magnitude 9.0.<\/strong><\/span><\/p>\n<p><span style=\"color: #ccffff;\">The <strong>San Andreas fault<\/strong>, by contrast, runs about 750 miles under the northern California coast and parts of inland southern California. <strong>It is easily the world\u2019s most infamous fault, responsible for the 1906 earthquake that leveled large parts of San Francisco and the Loma Prieta that shook the same region in 1989.<\/strong><\/span><\/p>\n<p><span style=\"color: #ccffff;\">Unlike the Cascadia Subduction Zone, where plates are sliding under one another, <strong>the San Andreas Fault is known as a transform fault, the tectonic plates are moving laterally, sliding past each other. <\/strong><\/span><\/p>\n<p><span style=\"color: #ccffff;\"><strong>The two faults meet in an area known as the Mendocino Triple Junction<\/strong>. Now, Goldfinger has found evidence that <strong>a quake on one could trigger a quake on the other, in essence making for one giant seismic event that would span the entire west coast of the U.S.<\/strong><\/span><\/p>\n<p><span style=\"color: #ccffff;\">The <a style=\"color: #ccffff;\" href=\"https:\/\/agu.confex.com\/agu\/fm19\/meetingapp.cgi\/Paper\/500809\"><span style=\"text-decoration: underline;\"><strong>new results<\/strong><\/span><\/a> stem from the analysis of sediment cores from the Mendocino Triple Junction area. <strong>Those cores, pulled from canyons on the ocean floor, show evidence of earthquakes in the form of underwater landslides.<\/strong> Using carbon dating, <strong>Goldfinger found that nearly a dozen earthquakes occurred throughout history on both faults at the same time.<\/strong><\/span><\/p>\n<p><span style=\"color: #ccffff;\"><strong>Moreover, the analysis found no evidence for the stress transfer working in reverse \u2013 from south to\u00a0north.<\/strong><\/span><\/p>\n<p><span style=\"color: #ccffff;\">Well, when you have two big faults that connect directly, there\u2019s a pretty high probability they\u2019re going to interact in some way. So one fault triggering another, or even becoming synchronized with the other for a period of time, is not a fantastical scenario. It is actually a fairly likely scenario. It just isn\u2019t on the radar anywhere\u00a0yet.<\/span><\/p>\n<p><span style=\"color: #ccffff;\"><strong>But it\u2019s not so common to have linkage across two different kinds of faults, from a subduction zone onto a strike-slip fault.
