Historical earthquakes is a list of significant earthquakes known to have occurred prior to the early 20th century. As the events listed here occurred before routine instrumental recordings — later followed by seismotomography imaging technique, [1] observations using space satellites from outer space, [2] artificial intelligence (AI)-based earthquake warning systems [3] — they rely mainly ...
A pie chart comparing the seismic moment release of the three largest earthquakes for the hundred-year period from 1906 to 2005 with that for all earthquakes of magnitudes <6, 6 to 7, 7 to 8, and >8 for the same period. The 2011 Japan quake would be roughly similar to Sumatra. Earthquakes of magnitude 8.0 and greater from 1900 to 2018.
U.S. Geological Survey National Center in Reston, Virginia Earthquake animations from May 16 to May 22, 2010 Earthquakes around the world from April 23 to May 23, 2010. Since 2012, the USGS science focus has been directed at topical "Mission Areas" [8] that have continued to evolve. Further organizational structure includes headquarters ...

"Buildings Can Be Designed to Withstand Earthquakes.
Nearly 75% of the country is at risk for a potentially damaging earthquake in the next 100 years, according to a recently updated map from the U.S. Geological Survey. The map is the first to ...
Third, the NEIC pursues an active research program to improve its ability to locate earthquakes and to understand the earthquake mechanism. These efforts are all aimed at mitigating the risks of earthquakes to mankind; and they are made possible by the fine international cooperation that has long characterized the science of seismology.
According to the USGS, "ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes. These maps are used by federal, state, and local organizations, both public and private, for post-earthquake response and recovery, public and scientific information, as well as for preparedness exercises and ...
Earthquake locations are taken from the Centennial Catalog [1] and the updated Engdahl, van der Hilst and Buland earthquake catalog, [2] which is complete to December 2005. From January 2006, earthquake locations are from the United States Geological Survey's Preliminary Determination of Epicenters (PDE) [3] monthly listing.
