Japan is one of the strongest amongst the world powers that has proved to be a survivor time and again. Being located at a seismic zone, it is always at a risk of natural calamities such as earth quake. The country is well equipped with technologies and earth quake resistant infrastructure. However, the recent earthquakes followed by the series of blasts in the nuclear reactors have made their mightiest technologies and disaster management techniques bite the dust.
As a repercussion of the earthquake the country has shifted more than two metres away from the neighbouring Korean peninsula. According to the Korea Astronomy and Space Science Institute (KASSI), the Korean peninsula moved east up to five centimetres (two inches) while Japan shifted some 2.4 metres (7.92 feet) east.

Immediately after the biggest earthquake in 140 years, a 10-meter tsunami wave hit the coast of Japan, causing severe destruction. The tsunami has swept away everything that lay in its path - houses, streets, vehicles, bridges, farm lands making everything undistinguishable from rubble. Large-scale evacuations had been ordered to avoid loss of life. This tsunami is so powerful that warnings have been issued to Colombia and Peru as well. The aftershocks of the 8.9-magnitude earthquake are continued to be felt, with smaller earthquakes repeatedly striking the country.

The epicenter of this earthquake was about 240 miles away from Tokyo. After this event, reports of a possible tsunami hitting the Japanese coast were coming in. The Japanese Metrological Agency too issued tsunami warnings for the entire
pacific coast, and people were directed to evacuate. Earlier to this, more earthquakes of lesser magnitude (7.2 and 6.3) were experienced in the islands of Honshu. The countries under possible danger have been identified as: Russia, Taiwan, the Philippines, Indonesia, Papua New Guinea, Australia, New Zealand, Fiji, Mexico, Guatemala, El Salvador, Costa Rica, Nicaragua, Panama, Honduras, Chile, Ecuador, Colombia and Peru.
