Felt here on 5th & Makuu in Paradise Park - short but quite strong.

My unofficially guess would be 6.0

Looks like USGS listing a 3.4 up in Volcano at 10:02pm followed by a 3.9 magnitude down on the south flank at 10:03pm.

Hmm...

This doesn't quite add up; the daily activity for months in Volcano has been listed as over five and they have not been felt by me, the one last night felt as strong as first one on May 4 or 5, yet this one supposed to be 4.1!!

The daily quakes at the summit are not true quakes. They are equivalent to a 5 on the seismograph. If you are right up there in that area then it shakes like a 5 but not from a few miles away.

Last night was a true quake.

Edited to add this:
The reason the quakes at the summit are not true quakes is because it is simply an unstable collapse of earth or blast of land mass around the crater as pressure blows out. That is what is shaking. - I think
