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.

In its most general sense, the word earthquake is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear tests. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the epicenter.
A major earthquake measuring 7.4 hit Taiwan early Wednesday, killing 9 and injuring at least 1,000. A 7.4 earthquake is exponentially more destructive than the 4.8 quake that struck central New ...
The list incorporates high-quality earthquake source (i.e., origin time, location and earthquake magnitude) and fatality information from several sources. 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.
Detailed satellite images give a bird’s-eye view Turkish towns before and after the earthquakes hit, and of relief efforts. Satellite images show shocking destruction caused by Turkey ...
