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."
Guatemala City
Lying on the Ring of Fire, the Guatemalan highlands and the Valle de la Ermita are frequently shaken by large earthquakes. The last large tremor to hit the Guatemala City region occurred in the 1976, on the Motagua Fault, a left-lateral strike-slip fault that forms the boundary between the Caribbean Plate and the North American Plate. The 1976 event registered 7.5 on the moment magnitude scale. Smaller, less severe tremors are frequently felt in Guatemala City and environs.
