Scientists from the University of Miami said that magma is accumulating under the Mauna Loa shield volcano in Hawaii. This could lead to an earthquake and a catastrophic eruption, the journal Nature reports.
The team of experts studied the movement of the earth's surface, which was measured using satellite geodetic radars and GPS stations. As a result, it turned out that from 2014 to 2020, approximately 0.11 cubic kilometers of magma penetrated into the cavity in the earth's crust, formed after the cooling of hot rocks. The formation was located south of the caldera at a depth of 2.5-3 kilometers.
According to observations, in 2015, the magma accumulation expanded to the south, where the rock pressure is less, but in 2017, the deformation center returned to its previous position. Previously, such changes in the magma body under Mauna Loa were not observed.
In addition, the displacement of the surface under the eastern side of the volcano, located along the horizontal fault, was recorded. No movement was detected on the western side, which indicates the likelihood of an earthquake and subsequent volcanic eruption in the event of a further influx of magma.
Earlier, due to the consequences caused by the eruption of the Nyiragongo volcano in the Democratic Republic of the Congo, 13 people were killed.
