Seismology.
seismic waves
The device used to detect earthquakes is called a seismometer or seismograph. It measures the ground motion caused by seismic waves generated during an earthquake. By recording this data, seismometers help scientists analyze the magnitude and location of earthquakes.
Seismic Waves.
A seismograph works by detecting and recording the vibrations caused by seismic waves from earthquakes. It consists of a mass suspended on a spring that moves independently of the Earth's movements. When an earthquake occurs, the mass remains stationary due to inertia while the Earth moves, tracing out the shaking on a recording drum or digital display.
The fastest waves from an earthquake, also known as push waves, are called primary waves or P-waves. These seismic waves are the first to arrive at a seismograph station and they travel through solid rock and fluid at high speeds by compressing and expanding the material they pass through.
seismographs
The distance between a seismological recording station and the earthquake source is determined from the arrival times of seismic waves at the station. By comparing the arrival times of P-waves and S-waves, seismologists can calculate the distance to the earthquake source using the difference in their arrival times.
Earthquake waves are called seismic waves.
Longitudinal waves are called primary waves because they are the fastest seismic waves and are the first to be detected by seismographs in an earthquake. They are also known as P-waves because they are the first wave type to arrive at a seismograph station.
The distance between a seismological recording station and the earthquake source is determined from the arrival time of P and the S waves. P waves are faster than S waves and surface waves.
seismic waves
the energy of an earthquake, called seismic waves,originates from a point called the ? epicenter
The first wave to reach a recording station after an earthquake is the Primary wave, or P-wave. P-waves are compressional waves that travel faster than other seismic waves, moving through both solid and liquid layers of the Earth. They are followed by Secondary waves (S-waves) and surface waves, which arrive later and can cause more damage.
These are known as seismic waves.
The energy radiated in all directions from its source after an earthquake is called seismic waves. These waves include primary waves (P-waves), secondary waves (S-waves), and surface waves, which propagate through the Earth and carry the energy released during the earthquake. Seismic waves are responsible for the shaking and damage experienced during and after an earthquake.

Earthquake generated waves are called seismic waves. These are waves of energy that travel through the Earth's layers. Their velocity depends on the elasticity and density of the medium that they travel through.
