GEOLOGY

Detailed explanation-1: -A Tsunami is a series of huge waves that strike a coast. The waves are caused when massive amounts of water are displaced due to an undersea disturbance. Earthquakes, Volcanic Eruptions, Meteorites or even nuclear weapons testing can cause them.

Detailed explanation-2: -Thailand was one of the countries that was hit by the 2004 Indian Ocean earthquake and tsunami. Due to proximity of the Andaman coasts of Thailand situated just about 500 km east of the earthquake epicentre, the tsunami took just 2 hours to reach and strike the western coastline of the country.

Detailed explanation-3: -Earthquakes generally occur on three types of faults: normal, strike-slip, and reverse (or thrust). Tsunamis can be generated by earthquakes on all of these faults, but most tsunamis, and the largest, result from earthquakes on reverse faults.
