Strange phenomenon inside America's most dangerous volcano

Researchers have found strange events inside the Helens volcano in Washington. This volcano once erupted very strongly in the past, but now its interior is very cold.

The group of geologists from New Mexico University discovered the strange phenomenon when the Helens volcano took heat from another place. They still don't know why this phenomenon happened.

"This phenomenon has never been discovered or ever happened in other volcanoes. A volcano that takes heat from another place is a confusing phenomenon , " said geologist Steven Hansen. said.

In the past, the powerful eruptions of Helens volcano caused 57 deaths in 1980 and resulted in billions of dollars in physical damage.

The location of the Helens volcano is located at the Cascade arc - a chain of volcanoes that runs parallel to the Cascadia submerged zone from California to British Columbia. The strange thing is that the Helens volcano was formed 50km to the west of the arc, which is in a perfect position in the North-South direction.

Cascade arc is located in the area of ​​strong geological activity, where the tectonic plate Juan de Fuca pushes the North American platform above, causing the burned material to melt and become lava. But the Helens volcano is on a cold patch and scientists still don't understand why it is in such a position.

To find out what's going on. In 2014, Hansen and his team deployed thousands of sensors around the mountain to measure the movement of the ground. They then drilled 23 holes into the volcano, then poured some explosives into small earthquakes.

This experiment allows them to accurately track how seismic waves pass through the internal structures of the mountain, thereby understanding the temperature and the types of matter inside the mountain. The seismic waves yielded a rather strange shape, instead of a hot magma layer beneath the volcano, the team discovered a cold layer of serpentine rock .

With a history full of intense eruptions, the results really have no meaning and cannot explain anything. The results add new questions to researchers. Researchers believe that volcanic magma origin may lie to the east of the mountain, close to the rest of the Cascade arc. It has magma with temperatures up to 800 degrees C.

Researchers believe that the origin of volcanic magma may lie to the east of the mountain.

So from here geologists have led to a hypothesis that magma travels a distance of 50 km to the west to bring it inside Helens volcano and erupt. This is an unexplained strange phenomenon.

Geologists are now continuing to monitor future earthquakes to collect images of the movement of magma currents beneath the Helens volcano. From the result of the Helens volcano, we will learn more about other volcanoes in the world.
