What the record says
NCEI’s account, from the sources it cites.
The occurrence of sea level disturbance was confirmed by records of the Sarangani sea level monitoring station showing a drop of approximately 30cm and a maximum rise of approximately 10cm wave height relative to normal sea level. (reference #11790)
A 6.8-magnitude earthquake struck off the Philippines early Saturday, officials said, damaging several buildings and injuring two people as panicked residents fled the coast following a tsunami warning. Morallas said two people were injured during the evacuations in the Mindanao coastal towns of Glan and Malapatan. One person was hit by a falling rock while a pregnant woman hurt herself when she fell. (reference #11789)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
