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."
2011 Van earthquakes
The 7.2 () Eastern Highlands earthquake occurred inland on 23 October 2011 at 13:41 local time (EEST), centered about north-northeast of Van, Turkey and at an estimated focal depth of . Its focal region and much of easternmost Turkey lie towards the southern boundary of the complex zone of continental collision between the Arabian Plate and the Eurasian Plate, beyond the eastern extent of the Armenian and Asia Minor fault zones. Part of the convergence between these two plates takes place along the Bitlis-Zagros fold and thrust belt. The earthquakes's focal mechanism indicates oblique thrust faulting, consistent with the expected tectonics in the region of the Bitlis-Zagros Fault Zone, where thrust mechanisms dominate.
