WebEarthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate. That vibration pushes the adjoining piece of ground and causes it to vibrate, and thus the energy travels out from … Web3 de dez. de 2024 · Seismic waves are generated in earthquakes and they travel differently through different types of material. Seismic Waves: The slipping of land generates seismic waves and these waves travel in all directions. Earthquake is caused by vibrations in rocks.
