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."
2003 Colima earthquake
Several significant earthquakes have occurred near the recent event. In 1932, a magnitude 8.4 thrust earthquake struck about 100 km to the north-northwest. On 9 October 1995, a magnitude 7.6 earthquake struck about 50 km to the northwest killing at least 49 people and leaving 1,000 homeless. The most deadly earthquake in the region occurred about 170 km to the south-east on 19 September 1985. This magnitude 8.0 earthquake killed at least 9,500 people, injured about 30,000, and left 100,000 people homeless.Sources
