a underwater volcanoes The newest one has finally been found. He is only three years old but the eruption continues.
Underwater volcanoes recently discovered by researchers off the coast of Africa. Quoted from Live Science, the discovery is caused by a volcano that continues to rock or erupt without stopping.
The eruption is even claimed to be the largest ever recorded by humans. The eruption produced a strange (seismic) sound wave that sounded like a low-frequency ‘hum’ sound.
“We’ve never seen anything like this,” said the expedition leader to Nathalie Feuillet’s research site using the Marion Dufresne ship.
In the research of Feuillet who works at the Institute of Geophysics in Paris (IPGP), this underwater volcano is very large. Over the course of several months, they recorded thousands of vibrations from a depth of 20-50 kilometers under the sea. In fact, this finding goes further than previously thought.
According to data and images, this volcano appears to have formed on the seabed and is still growing. Not until there, the research team conducted monitoring and collected initial data on its existence.
Underwater volcanoes it is located 50 kilometers from the east coast of Mayotte. The area is in the Indian Ocean between Madagascar and Mozambique. This natural appearance materialized in just six months.
The researchers found the mountain came from a large magma chamber that sits in the mantle beneath the crust. Next there is tectonic movement to break up the rock that allows magma to rise.
This event creates an embankment and generates vibrations. Magma reaches the ocean floor and goes into the water and cools and hardens. Finally, a mountain is formed with a height of up to 820 meters.
According to Feuillet, his team never expected to find an underwater volcano. Moreover, the strange sound that was caught in November 2018 may have circled the world, but no one has asked why.
The suspicions of Feuillet’s team started with a ‘hum’ sound with a uniform frequency. This sound is clearly different from the sound of an earthquake which has many frequencies. The sound cannot be detected as p-waves or s-waves.
The sound of the latest underwater volcano was detected by six seismometers on the ocean floor. This tool captures earthquakes that occur very tightly in the deep folds of the earth. This movement shakes the magma chamber where steam escapes from the rock layers on the ocean floor.
It is estimated that the volcanic vomit reaches five cubic kilometers. Be the biggest on record. The research team also added that underwater volcanoes can erupt or make volcanoes in the vicinity become active.
