In its most general sense, an earthquake is any seismic event—whether natural or caused by humans—that generates seismic waves. Earthquakes are caused mostly by the rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, fracking and nuclear tests.

[ 33 ] [ 34 ] 2013 Okhotsk Sea earthquake magnitude M w 6.7 aftershock was an extremely deep (640 kilometers (400 miles)) supershear as well as unusually fast at "eight kilometers per second (five miles per second), nearly 50 ...
Cryoseisms are often mistaken for minor intraplate earthquakes. [5] [9] Initial indications may appear similar to those of an earthquake with tremors, vibrations, ground cracking and related noises, [4] such as thundering or booming sounds. [7] Cryoseisms can, however, be distinguished from earthquakes through meteorological and geological ...
What causes a frost quake? The recent frost quakes are caused by a combination of the weather and the moisture in the ground, Jones said. Storms delivered several inches of snow to the area last ...
An earthquake is a phenomenon that results from the sudden release of stored energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement of the ground and sometimes cause tsunamis, which may lead to loss of life and destruction of property. An earthquake is ...
The initial report from a state geologist on Thursday was that the sound likely was caused by a sonic boom from military aircraft. ... was an earthquake, however, earthquakes are “extremely rare ...
