The Nature of Earthquakes
Earthquakes, seismic phenomena resulting from the sudden release of energy in the Earth's crust, are fundamental geological events with significant implications. Characterized by shaking and vibration, they occur due to the movement of tectonic plates, fault lines, or volcanic activity. Understanding the nature of earthquakes involves examining their causes, including plate tectonics and volcanic eruptions, as well as their effects on the Earth's surface and human structures. The study of earthquakes, known as seismology, plays a crucial role in assessing seismic hazards, enhancing disaster preparedness, and advancing our comprehension of the Earth's dynamic processes.
