Earthquakes in the Aegean around Santorini and Ios

[Irish Rover]

Another 4+ in the last 15 minutes. As anyone who has experienced a prolonged swarm will tell you, it spooks everyone eventually.

No let up. 4.9 just 15 minutes ago preceded by 4.2.

yes we had (and will have) lots of quakes down here.
I'd dare say that Greeks and Turks nowadays wont get out of bed with less than 5.5 maybe 6 . I can only remember the 6.something in 1981 in Athens, where I did get out of the house and fooled around a bit in the nearby square, never bothered since (and sincerely hope not to have to ever!)
Regarding Santorini, all local scientists initially argued it's tectonic and nothing to do with the volcano.
Seems like last week they are changing and are slowly starting claiming that volcanic activity could be related.

Was reading an article explaining there are 3 "active" volcanos around Santorini, one in the middle (or so) of the old one (Santorini is basically the eastern half of the volcano, the other is underwater), another one which I dont remember much and the third one is NE (iirc) of the isle and starts at 500m deep and the cone comes up to 28m or so ...
The big issue with Santorini is that the awful greedy overdevelopment and the lack of control by corrupt planning/police authorities means that it's built in a way that half of the bldgs in the caldera would nicely tumble down to the water 200+m underneath in a nasty quake. Will it ever happen? anyone guess...

I suppose pointing out that the "ring of fire" around the Pacific is ascribed to the plate boundaries there demonstrates the connection between volcanoes and tectonics is analogous to trying to ascribe any given storm to climate change...

Indeed, this was the big new idea when I first studied geology in the early 1970s—it was a very exciting time to be a geology student! And still subject to doubt in those days - Soviet geologists especially took a long time to accept it, mainly because it isn't apparent in the geology of Russia and Siberia. Regions like the Eastern Mediterranean were poorly understood at the time, too - the major plates had been delineated (as you say, volcanoes and earthquakes are a good clue!) but the pattern of suspected minor plates in areas such as the Eastern Mediterranean where several major plates impinge at a more or less terrestrial boundary had not been resolved.

Earthquake activity this morning much closer to Amorgos than Santorini including a 4.9 in the last hour.

The frequency and severity of these tremorshas abated over the last week or so, TG. There hasn't been a +4 since 26/02.

An earthquake prediction went viral. Is it giving people false hope?

Earthquakes have continued in this area all year, although mostly below 3. Biggish one this evening - 4.8 off the SW of Amorgos.
