Terrible secrets inside the Pacific fire belt

Secrets inside the Pacific Ring of Fire, the region where the most terrifying earthquakes on Earth were first revealed to scientists by the scientists.

Previously, the 7km deep fracture line named Banda Detachment in eastern Indonesia was a mystery to scientists. But recently, an international research group has found the mechanism of the fracture formation that is thought to be the largest fault on Earth .

By analyzing the high resolution map of the Bandam seabed , geologists from the Australian National University (ANU) and Royal Holloway University (UK) have found that the seabed rock layer is cut deep by the row. Hundreds of parallel steep cliffs .

Earthquakes occur by fractures on the earth's crust.

These cuts indicate that a portion of the Earth's crust larger than Belgium or Tasmania is more likely to be separated by an extension of 120km along a crack.

Dr. Jonathan Pownall, Australian National University (ANU) said: "The abyss have been known 90 years ago but until recently, no one has been able to explain why it is so deep. Our research indicates the 7km deep abyss under the Banda Sea in eastern Indonesia formed by expanding along the largest open crack recorded on Earth's crust ".

GS. Gordon Lister of ANU's School of Earth Sciences adds that Banda Detachment is the result of a fault spreading over an area of ​​over 60,000 square kilometers on the ocean floor.

"We have found a rational explanation for the existence of the fracture, which we named Banda Detachment based on deep measurement data and regional geographic knowledge," said Professor. Gordon Lister said.

The discovery could make a breakthrough in predicting tsunamis in the ring of fire that surrounds the Pacific basin, which is famous for earthquakes and volcanic eruptions. According to Dr. Jonathan Pownall, knowledgeable about major faults like Banda Detachment in areas at high risk of tsunamis and large earthquakes is a basic condition to fully assess the dangers of tectonic activity of the Earth's crust. .

Super earthquake made "move" Japan

Japan is the meeting place of many different tectonic plates such as the Pacific, Asia-Europe, North America and the Philippines. This is the cause of the emergence of volcanoes and hot springs throughout the country. And by being right on the Pacific Ring of Fire, every century, Japan suffers from a few devastating earthquakes.

The total force of power generated from the magnitude of nearly 9 magnitude earthquakes in Japan on March 11, 2011 is equivalent to the explosion of 6.7 trillion cubic meters of TNT and about 1,000 times the destructive power of all even the world's nuclear weapons combined. The epicenter of this earthquake lies off Japan, so after the earthquake struck a tsunami with tremendous devastation. This is the cause of much greater casualties than earthquakes that normally occur on the ground.

This reminds us of the fact that earthquakes can have far more destructive power than earthquakes on earth.

This earthquake also caused Japan's main island to move nearly 2.5m and the tilting axis of the Earth was deflected by 10cm, CNN gave the information recorded by the US Geological Survey (USGS) and the Institute of Physics and Italian Earthquake.
