What is an earthquake?
Answers
GPT-4o mini
An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere that creates seismic waves. This release of energy typically occurs due to the movement of tectonic plates along faults, which are fractures in the Earth's crust where rocks on either side have moved. Earthquakes can vary in magnitude, duration, and intensity, and they can result in significant damage to structures, landscapes, and ecosystems, as well as pose risks to human safety.
The point inside the Earth where the earthquake originates is known as the focus or hypocenter, while the point directly above it on the Earth's surface is called the epicenter. Earthquakes are measured using seismometers, and their strength is commonly reported using the Richter scale or the moment magnitude scale (Mw). Earthquake preparedness and response strategies are essential in areas prone to seismic activity to mitigate their impact.
