It has recently been a 4th degree one at Vitoria-Gasteiz, in the North of Spain. One of the least probable places you would even think of have an earthquake...

Unfortunately Spain and Portugal have seen quite a few earthquakes over the centuries, some of them quite deadly:

This would be the tenth major earthquake (7+ magnitude) along the Pacific ring of fire this year. With the Kamchatka and other earthquakes in the news recently I had a fear that were building to some major event but turns out that this year is about average if not slightly below average for major quakes along the ring of fire.

I heard that smaller (relative) earthquakes actually lower the prob of larger ones, so maybe it is a good thing? A bunch of 7.X earthquakes in the ocean are not going to be hugely destructive.

Earlier quoted context omitted.

That's correct, if relatively small earthquakes would stop that could be the precursor to a much bigger one. It's like releasing tension gradually rather than all at once.

Isn’t that a myth? Do you have any sources to back up your claim?

NHK (english): https://www3.nhk.or.jp/nhkworld/en/news/20251209_02/ > The Japanese government set up a task force at the crisis management center in the prime minister's office at 11:16 p.m. on Monday in response to the earthquake. A thousand Naruto shadow-clones just got deployed. I'm not being cute, these guys are heroes and role-models to all.

(Thanks for the link - we've since merged the threads to a submission of that one. I've included the other major links that people have been posting in the toptext.)

That is correct, but OTOH there was a 7.3 foreshock two days before the 2011 Tōhoku earthquake.

So the only thing we can say for sure is that it is still extremely difficult to predict earthquakes.

There may be a new subduction zone forming in the Atlantic off the coast there.

This all happens in geologic slow motion, of course.

Today I got served this video "Earthquake and Liquefaction his Urayasu, Chiba 3/11/2011" [0], which is from the earthquake which caused the huge tsunami in Japan.

I have rarely seen something as scary as this.

The updated IGN website doesnt work properly for me. The old site was so much better, do you know if there is an alternative?

Was in a hotel in Sapporo, almost got thrown out of bed. Lot of people in the hotel lobby now. Considering leaving Hokkaido by air if a Hokkaido and Sanriku Subsequent Earthquake Advisory is issued, don't really want to be in a potential megaquake.

Good luck, the Sapporo Chitose airport is closed for inspection of both runways.

BTW, you are safer in hotel than outside. No need to stay in lobby, go to bed, just protect your head. I experienced much bigger one in Sapporo in 2018.
