SANTIAGO (Reuters) - More than 30,000 tremors have rocked Antarctica since the end of August, according to the University of Chile, a spike in seismic activity that has intrigued researchers who study the remote, snowbound continent.
Scientists with the university’s National Seismological Center said the small quakes - including one stronger shake of magnitude 6 - were detected in the Bransfield Strait, a 60-mile wide (96-km) ocean channel between the South Shetland Islands and the Antarctic Peninsula.
Several tectonic plates and microplates meet near the strait, leading to frequent rumbling, but the past three months have been unusual, according to the center.
“Most of the seismicity is concentrated at the beginning of the sequence, mainly during the month of September, with more than a thousand earthquakes a day,” the center said.
