Can take X-rays of the Earth by storm

By using a network of detectors in Japan, scientists have discovered a rare shockwave from deep within the Earth called the "weather bomb" emanating from a storm far from the North Atlantic.

This discovery marks the first time scientists have observed this particular type of shock, known as a seismic super wave.

The "weather bomb" in the Atlantic, is a fast-growing, strong storm that causes offshore waves to cause mild and deep tremors into the ocean's crust. These silent waves penetrate the Earth and can be detected in distant places like Japan, where for the first time there are devices used to measure the vibration amplitude of storms from P waves and S waves are called "Hi-net" methods .

Model of catching S wave from sea storm.

Peter Gerstoft and Peter D. Bromirski argue that the team's findings have given seismologists a new tool to study deeper structures in the Earth. It will contribute to a clearer picture of Earth's movements, even those that originate from the ocean-atmosphere system.

These mild tremors are called micro seismic waves . This is caused by the rushing waves of the ocean on solid ground while the storm takes place. We can detect anywhere in the world, micro seismic can in many different waveforms move through the surface and inside the Earth.

P and S waves are Body waves that pass through the interior of the Earth.

So far, scientists analyzing small earthquake activity only point to the P wave line (animals can feel before an earthquake happens). And S waves are very difficult to observe (the kind of waves people feel when they earthquake).

Here, researchers use 202 Hi-net stations operated by the National Institute of Science Research and Disaster Prevention in Chugoku district of Japan, Kiwamu Nishida and Ryota Takagi. They found not only the shock wave P but also the S-wave with a very small amplitude created by a North Atlantic storm, known as a weather bomb.

The structure inside the Earth still has many mysteries.

Moreover, the authors identified both directions as the distance and the place where the information waves originated and the structures of the storm passed. In this way, seismic energy moves from this impact through the Earth. The findings of Nishida and Takagi provide not only a new means but also to explore the inner structure of the Earth, in addition to contributing to more accurate detection of earthquakes and storms.
