I see 11 4.0+ earthquakes in the Aleutian Islands today, all near the same place. It makes me wonder if an Alaskan volcano is getting ready to blow or something.

neic.usgs.gov...

I looked at the data pages for Alaska volcanos, but didn't find any updates about earthquake swarms for any of the volcanos.

Or I suppose it could be fore-shocks for something big earthquake wise coming that way ....

Anybody here an unofficial expert in Alaskan volcanos and or earthquakes?

RAT ISLANDS, ALEUTIAN ISLANDS
I noticed a similer cluster on June 10, and another May 29-30.
(just a filler for those that don't know the area)
Aleutian Islands , chain of rugged, volcanic islands curving c.1,200 mi (1,900 km) west from the tip of the Alaska Peninsula and approaching Russia's Komandorski Islands. A partially submerged continuation of the Aleutian Range, they separate the Bering Sea from the Pacific Ocean. The Aleutians comprise four main groups: Fox Islands, nearest to the mainland, including Unimak, Unalaska, Umnak, and Akutan; Andreanof Islands, including Amlia, Atka, Adak, Kanaga, and Tanaga; Rat Islands, including Amchitka and Kiska; and Near Islands, the smallest and westernmost group, including Agattu and Attu. The Semichi Islands, of which Shemya is the largest, are nearby.

But this is a very geo-active area and could mean nothing. Let's hope it's not a precurser to something bigger.

I also took a look at the southern end of Vancouver Island, and that area looks very calm for a change, with very few tremors.

I just wonder if that huge quake that cause the tsunami and the one that followed shortly after, hasn't put stess on other areas of the globe.

(edit to add....... The yellow dot on the map is in an area that shakes all the time. It's the most active area around Vancouver Island)
