Sagot :

Answer:

No, all earthquakes do not cause tsunamis. There are four conditions necessary for an earthquake to cause a tsunami:

(1) The earthquake must occur beneath the ocean or cause material to slide in the ocean.

(2) The earthquake must be strong, at least magnitude 6.5.

(3) The earthquake must rupture the Earth’s surface and it must occur at shallow depth – less than 70km below the surface of the Earth.

(4) The earthquake must cause vertical movement of the sea floor (up to several metres).
