Satellite images show the rare disaster caused by the tsunami triggered by the earthquake in Japan. The left image was taken on April 4, 2010, in the Natori area of Japan, and the right image was taken on March 12, 2011, showing the same area after the earthquake and tsunami.
[Magnitude]
On the 13th, the Japan Meteorological Agency revised the earthquake magnitude from Richter 8.8 to Richter 9.
[Death Toll]
The official death toll confirmed by Japan is 2,100, but the police chief of the severely affected Miyagi Prefecture, Naoto Takeuchi, said: "There is no doubt the death toll will reach tens of thousands."
[Missing Persons]
About 20,000 people are missing.
[Number of Evacuees]
Currently, more than 450,000 people are taking refuge in evacuation facilities across Japan.
[Number of People Evacuated]
On the 13th, the United Nations Office for the Coordination of Humanitarian Affairs stated that about 590,000 people have been evacuated in Japan since the earthquake and tsunami, including 210,000 people living within 20 kilometers of the Fukushima nuclear power plant.
[Rescue Forces]
Naoto Kan requested increasing the number of Self-Defense Force personnel involved in search and rescue from 50,000 to 100,000.
Energy Twice That of Magnitude 8.8
On the 13th, the Japan Meteorological Agency stated that based on detailed information collected after the "3.11" earthquake, the agency finally revised the earthquake magnitude to Richter 9.
After the earthquake on the 11th, the Japan Meteorological Agency initially issued a rapid earthquake report. The United States and some Asian countries, based on monitoring data, measured the magnitude of Japan's "3.11" earthquake as Richter 7.9. A few hours later, the Japan Meteorological Agency announced the magnitude as Richter 8.4, and on the evening of the 11th, it was adjusted to Richter 8.8. According to international practice, the closer the seismic network is to the earthquake, the more accurate the seismic data. Furthermore, with a deeper understanding of the earthquake's destructive power, Japan finally determined the "3.11" earthquake magnitude to be Richter 9.0.
The Japan Meteorological Agency said that the energy released by the magnitude 9.0 earthquake is 45 times greater than the initial rapid report of 7.9 and twice that of 8.8.
On the 13th, the United States Geological Survey stated that the Richter 9.0 earthquake in Japan is the fourth largest earthquake worldwide since 1990. So far, the highest magnitude earthquake worldwide since 1900 was the Richter 9.5 earthquake in Chile in 1960, which caused more than 5,700 deaths.
Japan Island Shifted 2.4 Meters
CNN quoted geophysicist Chen Shengzhao from the United States Geological Survey reporting that the strong earthquake caused a crack about 400 kilometers long and 160 kilometers wide in the seabed crust.
Additionally, USGS geophysicist Hedernat said that Honshu Island in Japan may have moved 2.4 meters eastward due to the earthquake. "A GPS station moved 2.4 meters," Hedernat said, "and we have seen a map from the Geospatial Information Authority of Japan showing a large area displacement consistent with the movement of the entire landmass."
Largest Earthquakes Since the 20th Century
① Chile 1960 Magnitude 9.5
② Alaska 1964 Magnitude 9.2
③ Indonesia 2004 Magnitude 9.1
④ Russia 1952 Magnitude 9
⑤ Japan 2011 Magnitude 9
⑥ Chile 2010 Magnitude 8.8
⑦ Ecuador 1906 Magnitude 8.8
⑧ Alaska 1965 Magnitude 8.7
⑨ Indonesia 2005 Magnitude 8.6
⑩ Tibet, China, Zayu 1950 Magnitude 8.6

Naoto Kan choked up several times while talking about the earthquake situation
Stated that Japan is facing the most serious crisis since World War II, Tokyo implements power rationing
On the evening of the 13th, Japanese Prime Minister Naoto Kan, wearing a blue rescue work uniform, held a press conference to express heartfelt condolences to all citizens and thanked the public for supporting the government's earthquake relief efforts.
Naoto Kan called the "3.11" earthquake the most serious crisis Japan has faced since World War II. When mentioning the losses caused to the Japanese people by the earthquake, Kan's eyes were filled with tears, and he choked up several times. He said that currently, the Japan Self-Defense Forces and international rescue teams have rescued 12,000 people, and the number of Self-Defense Forces personnel involved in disaster relief has reached 100,000.
Regarding the Fukushima nuclear power plant leakage incident, Naoto Kan stated that in the future, strict restrictions and management of similar accidents will be considered from a legal perspective.
Naoto Kan also specifically mentioned that Tokyo will start rolling blackouts from the 14th, hoping for public understanding. Due to the ongoing issues with the nuclear power plant, the possibility of repair in the near future is low, and some areas of Tokyo will implement planned rolling blackouts starting on the 14th.
Naoto Kan said the earthquake has severely damaged Japan's economy. According to Japanese officials, the government will use about 20 billion yen (2.44 billion USD) in emergency funds to support rescue efforts.
■ Forecast
The probability of a magnitude 7 aftershock exceeds 70%
On the afternoon of the 13th, Takashi Yokota, head of the Earthquake Forecast Information Division of the Japan Meteorological Agency, said the probability of an aftershock of magnitude 7.0 or higher occurring in Japan within the next three days exceeds 70%.
Takashi Yokota said that since the earthquake on the 11th, Japan has experienced more than 150 aftershocks of magnitude 5.0 or higher daily, with smaller aftershocks occurring even more frequently. Currently, the high-frequency aftershock areas remain in the heavily affected northeastern earthquake zone. The earthquake caused changes in the seabed crust of Iwate and Ibaraki Prefectures, making aftershocks more likely.
Takashi Yokota emphasized that before the earthquake on the 11th, Japan had already been in an active seismic period, and the "3.11" earthquake further increased Japan's seismic activity.
According to the assessment by the Japan Meteorological Agency, the probability of an aftershock of magnitude 7 or higher occurring within the next three days exceeds 70%.
Takashi Yokota said the Japan Meteorological Agency has issued aftershock warnings to various regions and does not rule out the possibility that a major aftershock could trigger another tsunami, urging coastal areas to be prepared.
