Yes, a major event shaking some of my in-laws awake. They are only 100km ( 60 miles) NW of the event.
This quake was a thrust faulting focal mechanism on a fault plane dipping to the WNW

from my seismograph ....

and a low gain sensor where the event phase arrivals can be more easily seen

A lot of activity in that area. Two images show 95 and 99 earthquakes, including the 7.6 Mag. The most recent would be in red.

The aftershocks continue to roll in from offshore eastern Mindanao with multiple M6+
and several high M5 events.
The latest about 3 hours ago ( at the time of writing this), a M 6,9
being the strongest aftershock so far.

My gram shows the tail of the 7.6 which within are buried several M6.2's and a M6.0.

Events M4.5 and up

This is one of the most active aftershock sequences that I can recall from a M7.6 event.
