Good day!

I am a student from Pamantasan ng Lungsod ng Maynila (PLM), taking Bachelor of Science in Civil Engineering. I am currently conducting my thesis as part of the curriculum which focuses on seismic vulnerability of Philippine General Hospital.

As part of the study, I needed to obtain the data regarding the earthquake motion acceleration (time history data) of Moro Gulf 1976 and Casiguran 1968 earthquakes. The ground motion data will be used for obtaining their peak ground accelerations (PGAs).

Thank you very much!
