A huge earthquake swarm was detected in Antarctica, which researchers say was likely the result of a long-dormant volcano awakening.
An earthquake swarm refers to incidents in which many seismic events occur in the same small area over a relatively short period of time without an accompanying mainshock.
According to a study published in the Nature journal Communications Earth & Environment, the swarm affected the Bransfield Strait—a body of water around 60 miles wide that is located between the northwestern tip of the Antarctic Peninsula and the South Shetland Islands.
The swarm of 85,000 earthquakes was the strongest seismic outburst ever recorded in Antarctica.
