The state typically experiences between 10 and 20 earthquakes above magnitude 2.0 each year, said Andy Newman, a professor of geophysics at Georgia Tech. As for what’s behind the recent shakes ...
Modern earthquake location still requires a minimum of three seismometers. Most likely, there are many, forming a seismic array. The emphasis is on precision since much can be learned about the fault mechanics and seismic hazard , if the locations can be determined to be within a kilometer or two, for small earthquakes.
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.
2006 Kuril Islands earthquake and tsunami – magnitude 8.3 earthquake, no injuries or fatalities anywhere; 2009 Samoa earthquake and tsunami – magnitude 8.0 earthquake with an epicenter 120 miles (190 km) southwest of American Samoa generated tsunami waves up to 16 feet (5 m), killing 34 people in American Samoa and causing extensive damage [39]

Anyone who felt the Nov. 28 earthquake is asked to call 601-961-5171 and report it to MDEQ. "If anyone did feel it, we'd like to know," Starnes said. "That would be worth documenting."
The strongest deep-focus earthquake in seismic record was the magnitude 8.3 Okhotsk Sea earthquake that occurred at a depth of 609 km (378 mi) in 2013. [22] The deepest earthquake ever recorded was a small 4.2 earthquake in Vanuatu at a depth of 735.8 km (457.2 mi) in 2004. [23]
The earthquake is now more deadly than the magnitude 7.8 quake in Nepal in 2015 which killed more than 8,800 people. Satellite images show shocking destruction caused by Turkey earthquakes 08:22 ...
