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 Colombia
The most devastating earthquake for Colombia happened on August 15 and 16, 1868 off the coast of Ecuador, leading to approximately 70,000 fatalities. The strongest earthquake, with an estimated moment magnitude of 8.8 also happened offshore Ecuador in 1906. Other major earthquakes were the 1875 Cúcuta earthquake with around 10,000 deaths and the 1999 Armenia earthquake with an intensity of X. The deepest registered earthquake happened in the department of Amazonas in 1970 at an estimated depth of almost . The 1785 Viceroyalty of New Granada earthquake sparked the birth of journalism in Colombia, initiated by Manuel del Socorro Rodríguez, six years after the publication of the "Aviso del Terremoto" about the earthquake with its epicentre in La Calera, Cundinamarca.
