According to the National Police Agency of Japan, as of December 10, 2020, the damage situation and police countermeasures related with the 2011 Tohoku district-off the Pacific Ocean Earthquake were 15,899 dead, 2,527 missing, and 6,157 wounded. Of these casualties, 5,081 were in Miyagi Prefecture, 1,421 were in Iwate Prefecture, and 361 were in Fukushima Prefecture.
The number of deaths could increase due to further recovery operations. At least 6,000 people are still listed as missing.
In terms of damage, 95% of buildings were found to be damaged or completely destroyed. The majority of these losses were recorded in Miyagi Prefecture where 11,175 structures were reported as damaged or destroyed.
The total economic cost of the disaster was estimated at $92 billion (2011 dollars). Of this amount, $20 billion was lost by businesses alone. The government provided $9.5 billion in aid, but most of it went toward repairing public infrastructure such as roads and power lines rather than helping individuals.
Including future costs for medical care and compensation payments, experts estimate that the total cost of the disaster will reach $150 billion.
About half of all deaths and a third of all injuries occurred in Miyagi Prefecture.
Casualties and property damage According to the Japanese National Police Agency, this severe earthquake and tsunami killed 15854 people, left 3167 people missing, and wounded 26992 people throughout twenty prefectures. It also destroyed over 125000 structures. The main island of Japan is called Honshu. The quake was near the northern coast of Honshu.
The death toll may never be known with certainty because many bodies are still trapped under the rubble of damaged buildings. Also, some victims who were not identified at first might have been buried by later waves.
In addition to the human casualties, the earthquake and tsunami caused extensive damage to infrastructure. Over 125000 houses and other buildings were destroyed. Power lines were down or damaged, leaving approximately 15 million people without electricity. About 3500 nuclear reactors had their cores melt due to power outages or system failures. That's about 10% of all nuclear reactors worldwide!
The number of deaths could have been much higher if not for heroic efforts of civilians who saved many lives by pulling out survivors from under the ruins of damaged buildings.
About half of all deaths occurred in Iwate Prefecture, which was completely devastated by the tsunami. Nearly 20,000 people are thought to have lost their lives in that single prefecture.
In 2020, 18 persons were injured or died in Japan as a result of earthquakes. The number of persons injured or killed by earthquakes peaked in 2011, when over 29 thousand people were killed or injured. The Great East Japan Earthquake, often known as the Tohoku Earthquake, happened that year. It was one of the most powerful earthquakes ever recorded and caused mass deaths and damage across northern Japan.
The deadliest earthquake in recent years occurred on March 11, 1995. A 9.1-magnitude quake struck the Kii Peninsula, near the city of Kumamoto. The death toll reached 6,000. Many more people lost their lives in smaller quakes that preceded the main event by several hours.
After the 1995 disaster, seismologists built stronger buildings, but they are still vulnerable to strong earthquakes. After the Fukushima Daiichi nuclear power plant was damaged by the 2011 tsunami, additional safety measures were taken to prevent another nuclear accident. However other natural disasters have also affected the country, such as typhoons and floods, which have caused many deaths themselves.
Deaths due to earthquakes are usually indirect results of these events. For example, after the 1995 disaster, more stringent building codes were introduced to prevent further loss of life. However, since most deaths occur during collapse of buildings, more attention needs to be paid to construction quality.
