Underground volcanoes off the US coast are about to erupt

Underground volcanoes off the US coast "wake up" and can erupt lava under the sea.

Axial underground volcano is about to erupt off the US coast

Axial underground volcano is about 900 meters high from the ocean floor , about 480 km from the west coast of America. The researchers were warned about its underground eruption after noting major changes in the height of the seabed and the increase in small earthquakes on April 24.

Bill Chadwick, a geologist at Oregon State University and colleague Scott Nooner, a North Carolina University expert, has been monitoring Axial for the past 15 years, by measuring the movement of the sea floor when the volcano " swells ". same magma and then " deflate ". After the eruption in 1998, they predicted the next eruption would occur before 2016.

Last week, the center of the crater fell 2.4 m in 12 hours and the number of small aftershocks increased from hundreds to thousands every day, particularly on April 24, this number was 8,000. The measurement results were recorded from 8 seismic gauges around the edge of Axial's large crater, while the sensor system measured changes in water pressure.

According to Live Science, this is the first time Chadwick and his colleagues can observe the phenomenon of eruption in real time thanks to devices connected to a cable.
