❓ Frequently Asked Questions
Earthquakes are caused by the sudden release of energy stored in Earth's crust, primarily at plate boundaries where tectonic plates interact and build up stress.
Magnitude measures the energy released at the earthquake source, while intensity describes the effects of shaking at a specific location.
Seismologists use the arrival times of P and S waves at multiple stations to triangulate the earthquake's location using the difference in wave speeds.
P-waves are compressional waves that travel fastest, S-waves are shear waves that travel slower, and surface waves cause the most damage.
While short-term prediction is not yet possible, scientists can assess long-term earthquake probabilities and identify areas of high seismic hazard.
Aftershocks occur as the crust adjusts to the stress changes caused by the main earthquake, typically decreasing in frequency and magnitude over time.
Tsunamis are generated when earthquakes cause vertical displacement of the seafloor, creating waves that propagate across the ocean.
Friction along fault surfaces resists motion until stress exceeds the frictional strength, causing sudden slip and earthquake generation.
Scientists analyze how seismic waves travel through Earth's interior, using their speed and paths to infer the structure and composition of different layers.
Ground shaking intensity depends on earthquake magnitude, distance from the source, local geology, and soil conditions that can amplify or dampen seismic waves.
