This is as close as I could find. Still think Guam?

yup still think its Guam

after about an hour or so it was downgraded to a M 6.7
Its just on 137 km deep so that explains its lack of an extended period of surface waves.

For me here in Sydney, Australia, for quakes down the western side of the Americas ( nth, cntrl, sth) I start seeing them at ~ M 5.8. I can determine (clearly recognise) P and S arrivals at ~ M 6.5

Mount Mayon, on the SE tip of Luzon in the Philippines, is currently erupting. Evacuations are underway should a more catastrophic eruption occur:

yes that's correct, fortunately it was offshore rather than right underneath Guam

My Wife if from the Philippines. We haven't been to Mt Mayon yet ... its on that "to do" list
Travelling in the Philippines isn't much fun. The transport system is diabolical and the roads are even worse and the SE end of Luzon is a long way off our usual beaten path

Have visited the Ta'al volcano (sthrn Luzon) a couple of times and taken a boat out across the crater lake to the central island cone that quietly smokes away

Actually there's a bunch of volcanoes in the western/SW Pacific that are on the to do list to visit
Time and money both lacking
