GENERAL GEOLOGY

Detailed explanation-1: -Seismology is the study of earthquakes and seismic waves that move through and around the Earth. A seismologist is a scientist who studies earthquakes and seismic waves.

Detailed explanation-2: -Seismologists who focus on observation record and analyze data from the thousands of earthquakes, both big and small, that occur around the world every year. They often work in observatories or analysis centers, which are usually built and supported by universities or national governments.

Detailed explanation-3: -Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. A seismometer is an instrument that records the shaking of the Earth’s surface caused by seismic waves.

Detailed explanation-4: -Geologists record the seismic waves and study how they travel through Earth. Different types of seismic waves behave differently. The speed of the waves and the paths they take reveal the structure of the planet. Using data from seismic waves geologists have learned that Earth’s interior is made up of layers.

Detailed explanation-5: -Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network.
