From The LA Times:
Scientists say the Sierra’s eastern front is long overdue for a large earthquake along the California-Nevada line, where a magnitude 7 event expected on average every 30 years hasn’t occurred in six decades.
Nevada Seismology Laboratory Director Graham Kent says the region’s earthquake “drought” is likely one of the sources of a public misconception that it is at a low risk of experiencing a serious earthquake.
He planned to discuss details about the latest research Tuesday during an Earthquake Economic Resiliency Forum ahead of the Seismological Society of America’s annual meeting, running Wednesday to Friday in Reno.
Experts are gathering in Nevada days after powerful earthquakes killed hundreds of people in Ecuador
Kent said a magnitude 6 earthquake or larger typically strikes every 10 years or so along the Sierra Nevada frontal fault system running from south of Yosemite National Park to north of Reno and Lake Tahoe. There were seven magnitude 6.5 or larger in the region from 1915 to 1954, but none since, he said. The last magnitude 6 was 22 years ago in the Carson Valley south of Carson City.
The Federal Emergency Management Agency estimates a magnitude 6 quake could cause up to $1.9 billion in damage in the Reno-Sparks area and $590 million in the populated area of South Lake Tahoe, Kent said.
“Let’s take advantage of this extraordinary quiescent period in our earthquake history,” Kent said. “We have a great opportunity to bring experts together with our community — those who need to put plans in place not only for disaster response but, just importantly, a plan for quick economic recovery.”
The experts are gathering in Nevada days after powerful earthquakes killed hundreds of people in Ecuador (magnitude 7.8) and killed dozens and wounded thousands in Japan (magnitude 7.1). Scheduled speakers Tuesday include Dick McCarthy, executive director of the California Seismic Safety Commission, and Cory Lyman, director of the Salt Lake City Emergency Management’s “Fix the Bricks” program.
