Japan's Fukushima 'worst in history'

Japan's Fukushima 'worst in history' Video Clips. Duration : 3.13 Mins.


At least one billion becquerels a day of radiation continue to leak from Japan's Fukushima nuclear plant after the March earthquake and tsunami. Experts say that the total amount of radiation leaked will exceed amounts released from Chernobyl, making Fukushima the worst nuclear disaster in history. Al Jazeera's Steve Chao reports from the Japanese capital of Tokyo.

Worst earthquake in history

The term "earthquake" can be used as seismic activity generated seismic waves and the release of large amounts of energy are defined under the crust of the earth. The intensity of earthquakes tend to vary considerably from the days when the experience is almost negligible due to size, immense destruction of lives and property.

The effect of an earthquake is measured by the Richter scale, except for an area of ​​1 10 Even if the world has beaten many times with highThe intensity and extent of earthquakes, one of its variants have been disastrous experiences in China.

The worst form of this natural disaster ever known to mankind is the Shaanxi earthquake or Hua County earthquake called. The event that sends tremors still goes back to back on 23 January 1556 The epicenter of this colossal disaster was recorded as the valley of the Wei River in Shaanxi province, near Huayin, Huaxian and Weinan. With an approximate measure of 8 on the Richter scale,The earthquake caused the deaths of nearly 830,000 people. The death toll was high because of the landslides triggered in the region resulting from the earthquake.

In addition to the damage to life, the earthquake also led to changes in the physical properties of the country in view of the apparently irreversible changes in the mountains and waters. One of the most important changes of this earthquake is credited with the decline in the amount of the Small Wild Goose Pagoda in Xi'anProvince. The height of the wall went 40-5 meters to 43.5 meters.

While the greatest loss of lives lived in the earthquake of Shaanxi, was given the magnitude of the worst earthquake was the Great Earthquake in Chile earthquake measuring 9.5 on the Richter scale struck May 22, 1960. This natural disaster resulted in the loss of lives and devastation of the 1655 accounts for $ 800 million. While many of the other natural disasters such as floods can be predicted, butthe same is not possible for earthquakes. It is a technique developed until the time for the same by seismologists, humanity will have to bear the fatal consequences.

Earthquake Facts History

1.The 'largest earthquake recorded in the United States was a magnitude 9.2, that the Prince William Sound, Alaska, on Good Friday March 28 1964 UTC beaten.
2.The 'largest earthquake recorded in the world was a magnitude 9.5 (MW) in Chile in May 22, 1960.

3.The 'before the earthquake was reported in California in the 1769 expedition of Gaspar de Portola felt, while the group of 48 kilometers (30 miles) southeast of Los Angeles was at the campsite. 4. Before electronics allowed recordingslarge earthquakes, scientists built large spring-pendulum seismometers in an attempt for a long time to allow this movement generated earthquake records. The largest weighed about 15 tons. It is a medium sized three stories high in Mexico City, which is still running one. 5. The moving average San Andreas Fault Zone in the last 3 million years is 56 mm / a (2 / year). This is about the same rate at which fingernails grow. Assuming this rate continues, scientistsProject, Los Angeles and San Francisco are next to each other in about 15 million years. 6. The East African Rift System is a 50-60 km (31-37 miles) wide zone of active fault and volcanic rocks that extends from north to south in eastern Africa for more than 3000 km (1864 miles) from north to Ethiopia the south of the Zambezi. This is a rare example of an active continental rift zone, where a continental plate attempting to split into two plates which are passed from oneanother. 7. The first "seismoscope pendulum to measure the vibration of the earth during an earthquake was developed in 1751, and it was not until 1855 that faults were recognized as the source of earthquakes. 8. Moonquakes ("earthquake" on the moon) does not occur, but occur less frequently and have smaller earthquakes on Earth. It seems that they are related to the tide, with the difference in distance between the Earth and Moon loads only. They alsoat great depth, about halfway between the surface and the center of the moon. 9. Although both waves, a tsunami and a tidal wave are two different independent phenomena. A tsunami is a wave in shallow water caused by the gravitational attraction between the sun, moon and earth. A tsunami is a tsunami from an earthquake or landslide (usually triggered by an earthquake), displacing the ocean water pollution. 10. The hypocenter of an earthquake is the position under theEarth's surface where the rupture of the fault begins. The epicenter of an earthquake is the location directly above the hypocenter on the surface of the earth. 11. The largest mountain range is the mid-ocean ridge, the extension 64.374000 kilometers (40,000 miles) from the Arctic Ocean to the Atlantic Ocean, Africa, Asia and Australia and the Pacific Ocean on the west coast of North America . Has a maximum height of 4,207 m (13,800 feet) above the base of the ocean depths. 12. The Worldcountry's largest mountain range is the Himalaya-Karakorum. It contains 96 of the world, 109 peaks over 7,317 m (24,000). The longest range is the Andes of South America, the 7564 km (4700 miles) in length. Both were the movement of tectonic plates created. 13. It is estimated that there are 500,000 detectable earthquakes in the world each year. 100,000 of these can be heard, and 100 of them cause damage. 14. It is thought that more damage has been done by the fire made afterSan Francisco earthquake of 1906, when the earthquake itself. 15. A seiche (pronounced Saysha) located in the pool of Californians during and after an earthquake. It is "an 'internal wave oscillating in a body of water" or, in other words, is the bubbling of water in the pool or body of water, caused by ground movement during an earthquake. It may continue for a few moments or hours, long after the generating force is gone. A seiche can also be causedby the wind or the tides. Earthquake Facts History
