‘Refine quake studies for disaster response’

MANILA, Philippines — Amid recent earthquakes that hit the country, experts can adopt other techniques in studying active faults nationwide, based on a study by the University of the Philippines-Diliman.

Researchers used advanced optical correlation and interferometry techniques to provide precise measurements of surface displacement.

Comparing pre- and post-quake satellite images and studying seismic waves allowed researchers to better analyze temblors and hazards.

“These methods are crucial for assessing earthquake risks and developing effective mitigation strategies,” they noted.

“Future research should consider integrating additional datasets, such as UAV (unmanned aerial vehicle) data, and applying these methods to other surface processes,” researchers said.

“By refining hazard models, improving geological assessments and closely examining slip estimates, we can achieve a deeper understanding of the region’s seismotectonic configuration, ultimately enhancing earthquake preparedness,” they added.

Published in the Natural Hazards and Earth System Sciences journal, the study was conducted by UP Diliman National Institute of Geological Sciences experts Khelly Shan Sta. Rita and Sotiris Valkaniotis, as well as UP Diliman Resilience Institute executive director Mahar Lagmay.
