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."
1951 East Rift Valley earthquakes
The 1951 East Rift Valley earthquakes () were a series of 735 earthquakes which struck eastern Taiwan from 22 October 1951, to 5 December 1951, four of which registered at 7 or more on the Moment magnitude scale, the largest of those being magnitude 7.3 and 7.8 quakes on November 24. Altogether the quakes killed 85 people.
