why is the Glen Coe super volcano in Scotland rumbling?

look at this link of recent EQs in and around the UK..

[link to quakes.bgs.ac.uk]

notice all four were 'felt'?

seems a bit strange for such small quakes 4-5 km deep to be felt, but there you go.

now look at WHERE they are popping..

(yes, i know they're only small quakes. it's WHERE they're popping that interests me)

..and compare it to these maps, of Glen Coe.

probably nothing, but might be an idea to keep this one in mind.

Glen Coe is the site of a prehistoric vei8 eruption.

OK, i know it won't erupt, (well, i HOPE it won't, anyway) but the site of an ANCIENT caldera is rumbling?

can't be good, that.
