The Icelandic Met Office (IMO) announced earlier today, that the total number of earthquakes in the region has exceeded 34,000 since the onset of the seismic swarm about 2 weeks ago.

For comparison, it had about 3,400 quakes in the whole of 2020, which also had shown elevated activity, while the average during the previous years was in the range of 1,000-3,000 quakes per year.

Comment: It certainly seems that seismic and volcanic activity have increased recently: Also check out SOTT radio's:


Attention

Swarm of 20,000 earthquakes could trigger Iceland's volcanoes to erupt

Fiery eruptions spewing from Iceland's volcanoes could follow the tens of thousands of earthquakes that have shaken the nation over the past fortnight, scientists fear.

Experts monitoring underground magma movements in the Reykjanes Peninsula, in southwest Iceland, are on tenterhooks. Seismic whispers and changes in the land's shape mean an "effusive volcanic eruption could occur", according to the Icelandic Meteorological Office (IMO). But so far, nothing has happened.

"That's something new. We didn't expect that," Dr Dave McGarvie, a volcanologist at Lancaster University said. The researcher told National Geographic that "people started wondering, what the hell is going on here?" when magma moving towards the earth's surface began to die down - after an eruption appeared to be just hours away.

Murmurs in the region, first detected over a year ago, have culminated in more than 20,000 earthquakes since activity began on 24 February, according to the IMO.

After the deadly earthquake came the sinkholes.

A central Croatian region about 40 kilometers (25 miles) southwest of the capital, Zagreb, is pocked with round holes of all sizes, which appeared after December's 6.4-magnitude quake that killed seven people and caused widespread destruction.

Scientists have been flocking to Mecencani and other villages in the sparsely-inhabited region for observation and study.

'Do not stay at home': Tsunami warning for parts of New Zealand after 8.1-magnitude earthquake in the Kermadec Islands

QUAKE
A tsunami warning has been issued for parts of New Zealand after a strong earthquake struck off the country's coast.

New Zealand's emergency agency has told residents in some areas to head for higher ground after a powerful earthquake struck the Kermadec Islands region early Friday, sparking fears of a tsunami.

The 8.1-magnitude quake was the third to strike the area on Friday morning local time, according to the New Zealand National Emergency Management Agency.

People near the coast must "move immediately to the nearest high ground, out of all tsunami evacuation zones, or as far inland as possible. Do not stay at home," the New Zealand agency states on its website.

The Kermadec Islands are 500 - 620 miles northeast of New Zealand's North Island. The East Coast of the North Island from the Bay of Islands to Whangarei, from Matata to Tolaga Bay including Whakatane and Opotiki and Great Barrier Island are all included in the Pacific nation's tsunami warning.
