- Abstract
- An assessment of the engineering aspects of the earthquake that occurred on the island of Mindanao in the Philippines on August 17, 1976 was made and was augmented by notes on seismology and social science observations and extracts from a preliminary report. Detailed information from the main shock is drawn from a USGS Earthquake Data Report in which 231 observations are summarized. Foreshocks, aftershocks, acceleration, and macroseismic reports are given in the introduction. Subsequent chapters describe site conditions, soil effects, damage to lifelines, tsunami damage, damage to buildings in Cotabato City, Zamboanga City, and residential and bridge damage. A summary and observations chapter focuses on the damage in Cotabato City, particularly in relation to ground motion characteristics and building and bridge design construction. The final chapter discusses social science observations on the response of Cotabato City.
