The 2011 earthquake off the Pacific coast of TÅhoku (æ±åå°æ¹å¤ªå¹³æ´æ²å°é, TÅhoku-chihÅ TaiheiyÅ Oki Jishin?), often referred to in Japan as Higashi nihon daishinsai (æ±æ¥æ¬å¤§éç½?) and also known as the 2011 Tohoku earthquake, the Great East Japan Earthquake,[fn 1] and the 3.11 Earthquake, was a magnitude 9.0 (Mw) undersea megathrust earthquake off the coast of Japan that occurred at 14:46 JST (05:46 UTC) on 11 March 2011, with the epicentre approximately 70 kilometres (43 mi) east of the Oshika Peninsula of TÅhoku and the hypocenter at an underwater depth of approximately 30 km (19 mi). It was the most powerful known earthquake ever to have hit Japan, and the fifth most powerful earthquake in the world since modern record-keeping began in 1900. The earthquake triggered powerful tsunami waves that reached heights of up to 40.5 metres (133 ft) in Miyako in TÅhoku's Iwate Prefecture, and which, in the Sendai area, travelled up to 10 km (6 mi) inland. The earthquake moved Honshu (the main island of Japan) 2.4 m (8 ft) east and shifted the Earth on its axis by estimates of between 10 cm (4 in) and 25 cm (10 in).
Immediately after the incident at the Fukushima Daiichi nuclear power plant, as a result of the devastating tsunami which swept the country resulting thousands of casualties and damage amount to $40 billion, Japanese authorities quickly evacuated the local human population such that exposure to radiation could be kept at a minimum. The local wildlife, however, [...]
In light of recent catastrophic events that plagued Japan, and the consequent nuclear crisis recently raised to level 7 on par with Chernobyl, the talk of the day in every scientific and political circle seems to be that of nuclear safety. Armenia’s 31-year old only nuclear power plant located in Metsamor is one of the [...]
According to more than half of all Americans, God is in complete control of everything that happens on our planet. Slightly fewer people, 44 percent, believe natural disasters, such as the earthquake and tsunamis in Japan are caused by an omnipotent power; but hey, it gets a little better – only 29 percent of Americans [...]
The situation on the Fukushima nuclear plant is far from calming down, even after the government authorized water being dropped from helicopters, an option which was described as unnacceptable. It is even more unclear what the effect of that water will be, as helicopters threw it without hovering, presumably because of the radiation. Also, this [...]
It’s no mystery for anybody that the earthquake in Japan is one of the largest ever to be recorded in history, and it’s no mystery for anybody that Japan is an area with numerous seismic events, but the magnitude of this one exceeded greatly all expectations, even the most pessimistic one. The 8.9 magnitude (or [...]
This picture, created by a computer model at NOAA displays the expected heights of the tsunamis created by the 8.9 earthquake in Japan (which may be “upgraded” to 9.0 – calculating magnitudes is a pretty delicate issue). Of course the largest wave heights are expected near the epicenter, off the coast of Sendai, Honshu, Japan. [...]
