30,000 tremors have rocked Antarctica since the end of August, scientists say

Scientists say the seismic activity in Antarctica since the end of August is unusual.

Scientists say the seismic activity in Antarctica since the end of August is unusual.
Scientists at the University of Chile record the spike in seismic activity - including one strong quake of magnitude 6.

More than 30,000 tremors have rocked Antarctica since the end of August, according to new research.

Scientists at the University of Chile recorded the spike in seismic activity while studying the remote icy continent.

The university's National Seismological Centre said the small quakes - including one stronger one of magnitude 6 - were detected in the Bransfield Strait.

This is a 60-mile wide 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, researchers said.

Turkey's disaster authority and the U.S. Geological Survey say a 5.0 magnitude earthquake has struck Siirt in southeastern Turkey.

The Disaster and Emergency Management Authority, or AFAD, said on Dec. 3 there were no immediate reports of casualties or damage from the quake that hit at a depth of 20 kilometers (12 miles) at 8:45 a.m. (0545 GMT).

Turkey is crisscrossed by fault lines and was hit by two strong tremors this year - one that hit the western port city of Izmir last month, killing 117 people, and another in Elazığ province, killing 41 people.

At least 17,000 people died in a powerful earthquake in northwest Turkey in 1999.

Taal Volcano (taken October 26, 2020).
Five volcanic earthquakes were recorded in Taal Volcano in the last 24 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Wednesday.

In its 8 a.m. volcano bulletin, Phivolcs said Taal Volcano also emitted steam-laden plumes at the main crater vents.

Weak to moderate degassing activity in Daang Kastila Trail were also recorded in the volcano.

The agency also noted that the northwestern part of the Taal Caldera still has inflation while the southwestern part showed no changes after the Taal eruption.
