What is an Earthquake?
Earthquakes are natural events caused by the sudden release of energy in the Earth's crust, resulting in seismic waves that can lead to ground shaking, surface rupture, and in some cases, significant damage. They occur when stress built up along geological fault lines exceeds the strength of rocks, causing a slip along the fault. This process can happen at varying depths and magnitudes, influencing the intensity and impact of the earthquake experienced at the surface.
Earthquakes are measured using the Richter scale, which quantifies the size of an earthquake based on the amplitude of seismic waves recorded by seismographs. The scale is logarithmic, meaning each whole number increase represents a tenfold increase in measured amplitude and roughly 31.6 times more energy release. For instance, a magnitude 5 earthquake releases significantly more energy than a magnitude 4 earthquake.
Plate tectonics is the primary driving force behind earthquakes. The Earth's lithosphere is divided into several large and rigid tectonic plates that float on the semi-fluid asthenosphere beneath them. These plates constantly move, albeit slowly, due to convection currents within the mantle. When these plates interact, they can cause earthquakes at their boundaries, categorized as divergent, convergent, or transform faults.
