Information about issues relating to the 2011 Tohoku-Pacific Ocean Earthquake changes daily. At this current time, due to the large scale of damage caused by the earthquake and tsunami, prefectural governments in the affected areas are not currently accepting material donations and volunteer applications from individuals.  Please check individual prefectural websites (listed below) for updated information. On March 11, 2011, a magnitude-9 earthquake shook northeastern Japan, unleashing a savage tsunami. The total damages from the earthquake and tsunami are estimated at $300 billion dollars (about 25 trillion yen), according to the Japanese government. Scientists drilled into the subduction zone soon after the earthquake and discovered a thin, slippery clay layer lining the fault.
Residents of Tokyo received a minute of warning before the strong shaking hit the city, thanks to Japan's earthquake early warning system. Less than an hour after the earthquake, the first of many tsunami waves hit Japan's coastline. The earthquake shifted Earth on its axis of rotation by redistributing mass, like putting a dent in a spinning top. More than 5,000 aftershocks hit Japan in the year after the earthquake, the largest a magnitude 7.9.


In Norway, water in fjords pointing toward Japan sloshed back and forth as seismic waves from the earthquake raced through. The earthquake produced a low-frequency rumble called infrasound, which traveled into space and was detected by the Goce satellite. A selection of some of the startling facts and figures from the Japan earthquake and tsunami, which was one year ago this month. This is an aerial view of damage to Sukuiso, Japan, a week after the earthquake and subsequent tsunami devastated the area in March, 2011.
That record goes to the 2004 Banda Aceh earthquake and tsunami in Sumatra, a magnitude-9.1, which killed more than 230,000 people.
The country's stringent seismic building codes and early warning system prevented many deaths from the earthquake, by stopping high-speed trains and factory assembly lines. Researchers sailed offshore and dropped sensors along the fault line to measure the forces that caused the earthquake.
Japan relies on nuclear power, and many of the country's nuclear reactors remain closed because of stricter seismic safety standards since the earthquake.
But Japan's one-two punch proved especially devastating for the earthquake-savvy country, because few scientists had predicted the country would experience such a large earthquake and tsunami.


The great plates are rough and stick together, building up energy that is released as earthquakes. People in Japan also received texted alerts of the earthquake and tsunami warnings on their cellphones. The tsunami flooded an estimated area of approximately 217 square miles (561 square kilometers) in Japan.
In some regions, such as Miyagi and Fukushima, only 58 percent of people headed for higher ground immediately after the earthquake, according to a Japanese government study published in August 2011. Earthquake engineers examined the damage, looking for ways to build buildings more resistant to quakes and tsunamis. In the decade before the 2011 Tohoku earthquake, a handful of Japanese geologists had begun to recognize that a large earthquake and tsunami had struck the northern Honshu region in 869. Now, tsunami experts from around the world have been asked to assess the history of past tsunamis in Japan, to better predict the country's future earthquake risk.
