Swarm coincides with possible volcanic eruption.
In an email to Newsweek, Kristín Jónsdóttir, Earthquakes Hazards Officer for the Icelandic Meteorological Office (IMO), said the swarm is happening in a known fault zone called the Tjörnes Fracture zone. “Stress builds up in the zone because of tectonic plates which move past each other in opposite directions.”
“This is the largest earthquakes swarm in the Tjörnes Fracture Zone recorded in the past 40 years,” said Jónsdóttir.
The earthquake swarm coincides with signs a volcano to the south may be about to erupt. The IMO said activity at the volcano, which is one of Iceland’s most active, appears to be characteristic of an impending eruption.
Jónsdóttir said the earthquake swarm is not linked to the possible eruption.
