2100 People Confirmed Death &Nbsp At The 9 Level Of Japanese Strong Earthquake; 20 Thousand People Were Missing.

Satellite images show that the tsunami triggered by the Japanese earthquake caused a rare disaster. The left picture is the Japanese Natori area in April 4, 2010, and the right picture is the same area after the earthquake and tsunami struck in March 12, 2011.

[magnitude]

The 13 magnitude of Japan's Meteorological Agency revised the magnitude of the earthquake from 8.8 on the Richter scale to 9 on the Richter scale.

[death toll]

The number of deaths confirmed by Japanese officials is 2100, but Takeuchi Naohito, the chief minister of Miyagi Prefecture in the hardest hit area, said: "there will be no doubt that the death toll will reach tens of thousands."

[missing persons]

About 20 thousand people are missing.

[number of refugees]

At present, more than 450 thousand people are sheltering asylum facilities in all parts of Japan.

[evacuation numbers]

The United Nations Office for the coordination of Humanitarian Affairs, 13, said that after the earthquake, Japan has evacuated about 590 thousand people, including 210 thousand people living in the 20 km surrounding the Fukushima nuclear power plant.

[rescue force]

The number of self-defense personnel Naoto Kan asked for in search and rescue increased from 50 thousand to 100 thousand.

The energy is 2 times higher than the 8.8 level.

Japan Meteorological Agency said 13, according to the "3. 11" earthquake after the acquisition of detailed information, the meteorological department eventually revised the magnitude of the earthquake to 9 Richter scale.

After the 11 day earthquake, the Japanese Meteorological Agency issued an earthquake quick report. According to the monitoring data, some of the countries in the United States and Asia determined that the magnitude of Japan's "3. 11" earthquake was 7.9 on the Richter scale. A few hours later, the Japan Meteorological Agency announced that the magnitude of the earthquake was 8.4 on the Richter scale, and 11 magnitude later adjusted the magnitude to 8.8 on the Richter scale. According to international practice, the seismic data measured closer to the earthquake are more accurate. In addition, with an in-depth understanding of the destructive force of earthquakes, Japan finally determined the magnitude of the "3. 11" earthquake to be 9 on the Richter scale.

According to the Japan Meteorological Agency, the energy released by the magnitude 9 earthquake is 45 times higher than the 7.9 level of the initial report, and 2 times higher than that of the 8.8 class.

The US Geological Survey said on Wednesday that the magnitude 9 earthquake in Japan was the fourth largest earthquake in the world since 1990. So far, the world's highest magnitude earthquake since 1900 is the Richter scale 9.5 earthquake in Chile in 1960, which killed more than 5700 people.

Japan island translates 2.4 meters

The CNN quoted the geophysicist Chen Shengzhao of the US Geological Survey as saying that the strong earthquake caused cracks in the seabed crust to grow about 400 kilometers and 160 kilometers wide.

In addition, geophysicist Hudnut of the US Geological Survey said that the island of Honshu, Japan, could move eastward for 2.4 meters due to an earthquake. "A GPS base station has moved 2.4 meters," Hudnut said. "Moreover, we have seen a map of the Japanese Land Geography Institute, and found that the displacement of a large area coincide with the displacement of the whole land."

Reaction

Naoto Kan talked about the earthquake and choked with sobs.

Japan is facing the most serious crisis after World War II. Tokyo's power sluice is limited.

On the evening of 13 July, Japanese Prime Minister Naoto Kan held a press conference in the Blue Rescue clothing, expressing heartfelt condolences to all the people and thanking the nationals for supporting the government's earthquake relief work.

Naoto Kan referred to the "3. 11" earthquake as the most serious crisis facing Japan after World War II. When it came to the damage caused by the earthquake to the Japanese people, Naoto Kan's eyes were filled with tears and even choked with sobs. He said that at present, the Japanese self defense forces and international rescue teams have rescued 12 thousand people, and the number of self defense forces involved in disaster relief has reached 100 thousand.

On the Fukushima nuclear power plant leak, Naoto Kan said he would consider strictly limiting and managing similar incidents from a legal point of view.

Naoto Kan also mentioned in particular that from 14 days, Tokyo began to slam the electricity, and said it wanted people to understand. Because of the stalemate of nuclear power plants, the possibility of repair is not very large recently. Some parts of Tokyo have begun to implement the planned power restriction on the 14 day.

Kan said the earthquake has seriously damaged the Japanese economy. According to Japanese officials, the government will use about 20 billion yen (2 billion 440 million US dollars) of emergency funds to support the rescue.

Prediction

The probability of a 7 aftershock is over 70%.

On the afternoon of 13 July, Yokota Takashi, director of the earthquake prediction information of the Japan Meteorological Department, said that the probability of the aftershocks of magnitude 7 above Japan will exceed 70% in the next 3 days.

Yokota Takashi said that after the 11 day earthquake, more than 150 aftershocks of magnitude 5 or more occurred in Japan every day, and the frequency of small-scale aftershocks was higher. At present, the high incidence area of aftershocks is in the Northeast earthquake disaster area. The earthquake has caused the changes of the seabed crust in Iwate and Ibaraki counties, so it is more likely to cause aftershocks.

Yokota Takashi stressed that before the 11 day earthquake, Japan has been in an active period of seismicity, and the "3. 11" earthquake has strengthened the seismicity of Japan.

According to the judgment of Japan Seismological Bureau, the probability of occurrence of aftershocks of magnitude 7 or more will exceed 70% in the next 3 days.

Yokota Takashi said that the Japanese Meteorological Agency has issued aftershocks warning to all regions, and does not rule out the possibility of the next tsunami triggered by the aftershocks, and requires the coastal areas to take precautions against them.
