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."
List of earthquakes in 1974
This is a list of earthquakes in 1974. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Maximum intensities are indicated on the Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. Activity was once again below average with 11 events reaching magnitude 7+. The largest came in October in Peru when a magnitude 7.6 earthquake struck Lima. Other magnitude 7.0+ events shook the Caribbean, China and the southwest Pacific Islands. Two events dominated the 25,000 deaths during 1974. China was struck by a magnitude 6.8 event in May with upwards of 20,000 deaths. At the end of the year, Pakistan was struck by a modest 6.2 magnitude earthquake causing 5,300 deaths. Gabon in central Africa was hit by a rare earthquake in September.
