What is tsunami?:

What is tsunami? A tsunami , is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean, though it can occur in large lakes .

What is earthquake?:

What is earthquake? An earthquake (also known as a quake , tremor or temblor ) is the result of a sudden release of energy in the Earth's crust that creates seismic waves . The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. Earthquakes are measured using observations from seismometers .

Earthquake in Japan on 11th March,2011:

Earthquake in Japan on 11 th March,2011 Japan has a long tradition of earth quakes due to large number of volcanic eruptions taking place. On 11 th March, 2011 an earth quake measuring 9.0 on richer scale hit the northern Japan. The epicenter of earthquake lied in the sea bed near coastal line of Japan. The earthquake resulted in tidal waves up to height of 38.9 m or more striking the Japan coast with in a span of 10 minutes after earthquake. More than 140 aftershocks measuring more than 6.0 added further strengthening of disaster.

Loss due to Catastrophe :

Loss due to Catastrophe The Japanese National Police Agency has confirmed 15,421 deaths, 5,367 injured and 7,937 people missing across eighteen prefectures , as well as over 125,000 buildings damaged or destroyed. Around 4.4 million households in northeastern Japan were left without electricity and 1.5 million without water The earthquake and tsunami caused extensive and severe structural damage in Japan, including heavy damage to roads and railways as well as fires in many areas, and a dam collapse

Loss due to Catastrophe:

Loss due to Catastrophe Many electrical generators were taken down, and at least three nuclear reactors suffered explosions due to hydrogen gas that had built up within their outer containment buildings after cooling system failure. Residents within a 20 km (12 mi) radius of the Fukushima I Nuclear Power Plant and a 10 km (6.2 mi) radius of the Fukushima II Nuclear Power Plant were evacuated The overall cost could exceed US$300 billion, making it the most expensive natural disaster on record

More than 15,000 deaths in Japan.
