2011 Virginia earthquake
The USGS found that the farthest landslide from the 2011 Virginia earthquake was from the epicenter. This is by far the greatest landslide distance recorded from any other earthquake of similar magnitude. Previous studies of worldwide earthquakes indicated that landslides occurred no farther than from the epicenter of a magnitude 5.8 earthquake. The study suggested that the added information about East Coast earthquakes may prompt a revision of equations that predict ground shaking. "What makes this new study so unique is that it provides direct observational evidence from the largest earthquake to occur in more than 100 years in the eastern U.S. Now that we know more about the power of East Coast earthquakes, equations that predict ground shaking might need to be revised."
Eureka, California
The area regularly experiences large earthquakes as it is situated on the southern end the Cascadia subduction zone and near the San Andreas Fault, which interface around the Mendocino Triple Junction. On January 9, 2010, a 6.5 magnitude earthquake occurred about off shore from Eureka. After two seconds, it became a violent "jumper", making objects fly; the mostly vertical shocks from the ground led to broken windows in shops, overturned shelving in homes and stores, and damage to architectural detail on a number of historic buildings. Local hospitals treated mostly minor related injuries, and electrical power was out over a large area. Numerous natural gas leaks occurred, but no fires resulted. This was the largest recent earthquake since the April 25–26, 1992 sequence. It was followed on February 4, 2010, by a magnitude 5.9 earthquake which struck about northwest of the community of Petrolia and nearly west of Eureka. The shaking was felt within a radius, as far north as southern Oregon and as far south as Sonoma County. The largest recorded in the area was the 7.2 event on November 8, 1980. The larger earthquakes can pose a tsunami threat to coastal areas.
Eureka is located at (40.790022, −124.162752).
