What Causes Earthquakes?

Earthquakes are natural phenomena resulting from the sudden release of energy in the Earth's crust, leading to seismic waves. This energy release typically occurs due to the movement of tectonic plates, which are massive sections of the Earth's crust that float on the semi-fluid layer of the mantle. The edges where these plates interact are known as fault lines, and it is along these lines that most earthquakes occur.

Several factors contribute to the occurrence of earthquakes, including:

• Plate Tectonics: The movement and interaction of tectonic plates are the primary drivers of earthquakes.
• Volcanic Activity: Earthquakes can also occur in volcanic regions where magma movement stresses the surrounding rock.
• Human Activities: Activities such as mining, reservoir-induced seismicity due to filling large dams, and hydraulic fracturing can induce earthquakes.

Understanding these causes helps scientists predict potential earthquake zones and inform preventative measures. Although New York is not located near any major tectonic plate boundaries, it is still susceptible to earthquakes due to complex geological structures beneath the surface.
