Japan Earthquakes Hazard


Japan has been characterized as the one of the most vibrant earthquake countries in the world. There were around 1500 Japan earthquakes. Between 4 and 6 magnitude earthquakes were often happened.

In the history of Japan, there were large earthquakes could be counted such as in 1923, 1995 as well as 2011. There were in a total of tens of thousands casualties. Actually, there was also ten percent of all active volcanoes in the world were in Japan.

Japan earthquakes were generally happened because it was located on the plate boundary. That was on the fault, the earthquakes happened. In the case of 2011, the cause of earthquake was that Japan was situated at the North American plate near the boundary of Pacific and North American plates.

At this boundary, there was subduction zone. It was named so because the convergence of two tectonic plates. When the pace of the convergence was about 9 centimeters per year, the accumulation of tension were gradually increased. As a result, the earthquake was triggered when the tension were unlocked through break or crack on the fault. The fault was thrust fault because the tectonic plate called Pacific plate pushed beneath the North American plate.

Japan was also located on the north-west of Pacific ocean and on the Ring Of Fire which the name was sourced from the many volcanoes around Pacific. Because of those location factors, they could be threatened by large earthquakes and tsunami (another term of large ocean waves).

In the 2011, the earthquake of 9.0 magnitude and tsunami caused more than 18.000 deaths and losses. Another earthquake in 1995 caused more than 5000 deaths.  And the last one was earthquake in 1923 took more than 100.000 lives.

Earthquake Hazards

 

The popular hazard of earthquake is tsunami. It is a ocean wave that sweep across the shore as well as the towns near the coastline. The flames also took place in 1923 earthquake called the Great Kanto earthquake and in 1995 called the Great Hanshin earthquake.

The flames were immediately spread because of the condition of the houses made of the wood. The fire was caused by the broken gas pipes. The earthquake that happened in 2011 also caused the explosion of the Fukushima nuclear power reactors as the heat inside four nuclear plants were raising.

It was another earthquake hazards that caused further hazardous effect apart from the tsunami. 2011 Japan earthquake was regarded as the fifth biggest earthquake and the tsunami was regarded as the worst disaster in Japan since 1900.

 

The Most Recent Earthquake in 2011

 

Japan’ most hazardous earthquake in 9 magnitude happened in 2011. The earthquake could be the largest in Japan as well as was the fifth largest in world history. Casualties were counted at more than 18000 including ten of thousand getting lost. This was becoming the hardest tragedy in the world history.

The tsunami itself could destroy everything in the Japanese towns, wipe out many people’s lives and damage the nuclear reactors called Fukushima. It was the hardest time ever since.

There was also nuclear disaster in Chernobyl, Ukraine and Fukushima was one tenth of the effect of Chernobyl nuclear crisis. There might be still effects of the 2011 Japanese earthquake and tsunami such as the psychological effect. It was really one of the biggest and hardest effect of earthquake. The people there may consider to equip themselves with earthquake kit list and evacuation.
