A new study revealed that 85,000 earthquakes occurred in Antarctica towards the end of 2020. The source of the earthquake was an underwater volcano in action.
The Orca Seamount volcano, which has not shown any signs of activity for a long time near Antarctica, has reactivated. Base diameter extending approximately 900 meters above the seafloor about 11 kilometers The activity of the giant underwater volcano, which is 85 thousand different earthquakes triggered.
According to the study, the earthquakes occurred in Bransfield Strait, a narrow passage between the South Shetland Islands and the northwestern tip of Antarctica. Research with scientists from many nations, took place in 2020 revealed.
The largest were 5.9 and 6.0 magnitudes:
According to the results obtained from the research, the earthquakes occurred between August and November of 2020. Among the nearly 85,000 earthquakes that occurred in about 4 months, the two biggest ones were in October 2020. 5.9 magnitude and in November 2020 6.0 magnitude were earthquakes. It was stated that seismic activity decreased after the 6.0 earthquake that occurred in November.
Simone Cesca of the Geosciences Research Center in Germany, who led the research, emphasized that these processes do not normally fit into a human lifetime, but occur on geological time scales. He also explained how seismic activities decreased with the last earthquake.The 6 magnitude earthquake somehow caused some fractures and reduces the pressure of the magma set we think.” he explained.
