Mysterious Iceland Earthquake Swarm Hits Over 13,000 Quakes in 3 Weeks – That’s the Biggest Seismic Unrest in More than 40 Years Showing the Forces That Split the Island in Two
An ongoing earthquake swarm in Iceland has now reached over 13,000 quakes since it began on June 19.
This is the biggest swarm to hit the Tjörnes Fracture zone in the north of the country in almost half a century, and experts are unsure what is causing it.
The IMO said in its statement: “The earthquake swarm NE of Siglufjörður is still ongoing.
“The earthquake swarm began on 19th of June. Over 13.000 earthquakes have been detected, three of which measured greater than magnitude 5.
“The largest one was M5.8 on 21. June, around 30 km NNE of Siglufjörður. Other earthquakes above M5.0 were M5.6 and M5.4 on 20. June and were located around 20 km NE of Siglufjörður.
“Seismic activity if still ongoing and there are chances of more earthquakes of this magnitude occurring in the area.“
Earthquakes have been felt in the area surrounding the swarm. Some of the larger quakes have been felt as far as ReykjavÃc, 125 miles away.
KristÃn Jónsdóttir, Earthquakes Hazards Officer for the IMO said the swarm was the largest recorded in the Tjörnes Fracture Zone in the past 40 years.
