Sep 12, 2024 · earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth ’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.”. Earthquakes occur most often along geologic ...
Earthquakes do occur in Antarctica, but not very often. There have been some big earthquakes--including one magnitude 8.1 --in the Balleny Islands (between Antarctica and New Zealand). The boundary between the Scotia Plate and the Antarctic Plate just grazes the north tip of the Antarctic Peninsula (look "northwest" from the Pole toward South America).
Oct 18, 2022 · Learn how earthquakes occur when tectonic plates collide or move past each other, releasing seismic waves that shake the Earth. Find out how scientists measure and monitor earthquakes, and what benefits they have for the planet.
An earthquake is the shaking of the surface of Earth resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes may also be referred to as quakes, tremors, or temblors. The word tremor is also used for non-earthquake seismic rumbling. In its most general sense, an earthquake is any seismic event ...

Oct 11, 2024 · An earthquake is an intense shaking of Earth’s surface caused by movements in its outermost layer, the lithosphere. Learn how tectonic plates, faults, seismic waves and seismometers are related to earthquakes on Earth and other planets.
Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up ‘elastic strain’ energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake. Such movement on the faults is generally a response to long-term deformation and the buildup of stress.
