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."
2010 Baja California earthquake
The earthquake measured 7.2 on the moment magnitude scale that started south of Guadalupe Victoria, Baja California, at a depth of . It occurred at 22:40 UTC (1540 local time) on Easter Sunday, April 4, 2010, and it is said to have lasted about a minute and 29 seconds. Since the earthquake occurred on this day, it has been also called the Easter Sunday earthquake. Intensity VII ("Very strong") shaking was felt in Calexico, Imperial, El Centro, and Heber. Intensity VI ("Strong") shaking was felt in the Imperial Valley towns of Ocotillo, Calipatria, Brawley, and Holtville.
