How does an earthquake cause a tsunami?
Tectonic earthquakes are a common cause of tsunamis. They often occur in areas where two crustal plates are pushing against each other, forcing one plate to slide under the other. These earthquakes shift the crust of the earth, leading to a rapid drop or rise of sea floor.
What is a tsunami earthquake?
A tsunami earthquake can be defined as an undersea earthquake for which the surface wave magnitude M s differs markedly from the moment magnitude M w, because the former is calculated from surface waves with a period of about 20 seconds, whereas the latter is a measure of the total energy release at all frequencies.
