A tsunami is an ocean wave, or a sequence of waves, triggered by a sudden ocean floor disruption which displaces a vast amount of water. Tsunamis are usually caused by earthquakes, less frequently by underwater landslides, rarely by submerged volcanic eruptions and very rarely by massive impacts of meteorites in the ocean.
Explanation:
No, all earthquakes do not cause tsunamis. There are four conditions necessary for an earthquake to cause a tsunami:
(1) The earthquake must occur below the ocean surface, or allow material to slide into the ocean.
(2) Earthquake should be very intense - a minimum magnitude of 6.5 .
(3) The earthquake should crack the surface of the Earth and occur at a shallow depth - less than 70 km below the Earth's surface.
(4) The earthquake shall cause vertical displacement (up to several meters high) of the seabed.
