Question

Just wondering how are they linked? Can we prevent them from happening?

Answer 1

Earthquakes are the main reasons for tsunamis, the latest Japanese tsunami was triggered by the 8.9 magnitude earthquake, that hit the Japanese island, on friday 11th april. Earthquakes, disturb the plates in the seabeds, that triggers shocks in the seabed, hence disturburbing the water columns, that eventually rise and land on the shores.
