AND ECOLOGY The Science of Earthquakes Topics covered Earthquakes and its mechanism Types of earthquakes Sesmic waves (P-Waves, S-Waves, R-Waves, L-Waves) Swarms Reasons and place of origin Measuring earthquakes Shadow zones Earthquake perdiction Wadati–Benioff zone: Earthquakes along the Convergent boundary Distribution of earthquakes in the world and in India What Is An Earthquake? An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Seismic waves studies offer a full picture of the layered interior. Sometimes an earthquake has foreshocks. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. Aftershocks are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock Types of Earthquakes Tectonic earthquakes: The most common form of earthquakes, it is caused by the movement of loose fragmented pieces of land on earth’s crust knowns as tectonic plates. Volcanic earthquake: The less prevalent compared to the tectonic variety, these earthquakes happen before or after the eruption of a volcano. It is caused when magma leaving the volcano are filled by rocks being pushed to the surface. Collapse earthquake: This earthquake occurs in underground mines. The main cause is due to pressure generated within
