Seismic waves are waves of energy that travel through the Earth’s crust and are caused by sudden disturbances, such as earthquakes. These waves can be detected by seismometers and are used to measure the magnitude and location of an earthquake. Tsunamis, on the other hand, are huge waves created by earthquakes, volcanic eruptions, and other large-scale underwater disturbances. These waves are caused by a displacement of the water column and can travel thousands of miles before crashing into the shore. Tsunamis can cause extensive damage and loss of life, especially in areas where people live close to the shoreline.
