American scientists representing the University of Miami, drew attention to the process of accumulation of magma under the shield volcano Mauna Loa in Hawaii. As Nature writes, dangerous processes take place under the largest volcano on our planet.
Scientists analyzed data collected by GPS stations and geodetic radar and found that from 2014 to 2020, about 0.11 cubic kilometers of magma hit the dike-like body, which is located south of the caldera at a depth of about 2.5 – 3 km. At the same time, processes have been observed beneath the Mauna Loa volcano that have not been recorded before.
“We have detected a displacement of the earth’s surface near the eastern flank of the largest volcano – the displacement occurs here along a horizontal fault. Considering the fact that there is no displacement under the western flank, there is a high probability of an earthquake followed by a catastrophic eruption,” say researchers from the United States.
The Mauna Loa volcano, considered the largest on the planet, erupted in 1984 and 1950. In both cases, the eruptions were preceded by earthquakes – in 1950 the tremors occurred three days before the volcanic event, and in 1984 five months before. It is too early to tell when the volcano will wake up next, but scientists believe it could happen in the foreseeable future.
