Unusual Cluster of M6+ Earthquakes in Southern Philippines: What's Causing Them?

[davenn]

TL;DR Summary

Philippine quake

hi gang,

Another large quake in southern, central Mindanao, southern Philippines yesterday evening.
A M 6.8 widely and strongly felt across the island. This is the same area as 3 other M6 + events
in recent months. A screen shot from my seismograph here in Sydney, Australia and a location
map.

The M6.8 is the blue dot, the rest are aftershocks

cheers
Dave
