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."
October 2015 Hindu Kush earthquake
The last major earthquake in the same region of similar magnitude (7.6 M) was almost exactly ten years prior in October 2005, which resulted in 87,351 deaths, 75,266 injured, 2.8 million people being displaced, and 250,000 farm animals dying. The notable difference between this earthquake and the 2005 earthquake is the focal depth and its location with respect to the densely populated areas. The 2005 earthquake was 15 km deep and centered close to some densely populated areas while this earthquake was 212.5 km deep and centered farther from populated areas, reducing its damaging effects.
