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."
2016 Ecuador earthquake
At 18:58 ECT on April 16, a 7.8 M earthquake struck the coast of Ecuador approximately south-southeast of Muisne, in the province of Esmeraldas, at a depth of .
Tremors were felt in neighboring Colombia and Peru; a clinic in Cali, Colombia, was evacuated as a precautionary measure. A tsunami alert was issued by the Pacific Tsunami Warning Center for Colombia, Costa Rica, Ecuador, Fiji, Panama, and Peru. This is the largest earthquake to strike Ecuador since the 1979 Tumaco earthquake.
According to Mayor Gabriel Alcivar, much of the town of Pedernales, about 35 km to the south-southwest of the earthquake's epicenter, was leveled. In Guayaquil—approximately from the epicenter—an overpass collapsed on a car, killing the driver. In Manta the control tower of the airport was severely damaged; an Air Force officer was injured and the airport closed. Six homes collapsed and many others lost power in the nation's capital city of Quito.
