Answer:
Shifts and collisions of tectonic plates cause earthquakes.
The epicenter of an earthquake is the surface location directly above the quake’s hypocenter, the below-surface location where the rupture of the fault begins.
The scientific study of earthquakes is called seismology.
A magnitude 9.5 earthquake in Chile on May 22, 1960, is the most powerful earthquake in recorded history.
The largest-known quake in the United States struck Prince William Sound, Alaska, on March 28, 1964, and measured magnitude 9.2.
Earthquakes below magnitude 7.5 seldom cause tsunamis.
The 2004 Indian Ocean tsunami, which was created by a magnitude 9.1 earthquake near Sumatra, caused widespread damage in 14 countries.
