The Manila Observatory put a seismogram of the 6.7 shock online at
http://www.observatory.ph/cgi-bin/publications/pub_details.py?p=136
(note: all fields are optional in the fill-in field). It also caught
an earlier M5.2 earthquake in the Cotabato Trench.
This seismogram was taken before the major quake's aftershocks. It is
a very sensitive instrument, so of course the 6.7 sent it off the
scale, but it picked up the smaller waves - it's amazing how long they
go on afterwards in both quakes. Also, the seismogram is a good
visual demonstration of just how much difference there is energy
release during roughly 1 point on a logarithmic magnitude scale.
Also, Dr. Wikipedia notes that PAGASA will be deploying 10 of the
University of the Philippines' landslide early warning systems in five
susceptible areas this year. Would that help much for a sudden shock
like an earthquake, I wonder.

"It seems to me that every phenomenon, every fact, itself is the
really interesting object. Whoever explains it, or connects it with
other events, usually only amuses himself or makes sport of us, as,
for instance, the naturalist or historian. But a single action or
event is interesting, not because it is explainable, but because it is
true."
