b. Tsunamis

Explanation:

Tsunamis are sequence of huge waves caused by underwater earthquakes or volcanic eruption leading to large amount of deaths. The earthquake causes movement of the seafloor and the massive displacement of large amount of water which in turn leads to a Tsunami.

The earthquakes are as a result of the tectonic plates sliding each other causing faults and cracks on the earth crusts.
