Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Irish Sea earthquakes send tremors across British Isles

Posted by feww on August 26, 2013

Earthquakes felt both in Ireland and the UK

Two earthquakes struck in the Irish Sea early Sunday, said the British Geological Survey.

The strongest shock measured 3.3 on the Richter scale at a depth of about 5km some 25km off the coast of Blackpool at 10.58am (BST), and was reportedly felt by people on the British mainland.

An earlier quake measuring about 2.4 magnitude at a depth of 3km occurred about 4 hours earlier.


“The Irish National Seismic Network , which monitors seismic activity, has said that today’s earthquakes were ‘most likely the result of glacial rebound, the process whereby stresses built up the weight of glaciers from the last Ice Age are slowly released,'” said a report.

“It was not as strong as the Irish Sea earthquake on May 29th this year. The epicenter of the quake, which registered at magnitude 3.8, was 15km away from the town of Abersoch in Gwynedd, the British Geological Survey (BGS) said.”

A magnitude 4.0 quake struck the Iceland Region (62.90°N, 25.18°W) on Sunday at 07:00 UTC.

Local geologists would be advised to investigate connection between those quakes.
