Seismic survey — refraction, reflection, MASW, and Passive.
P-wave and S-wave seismic refraction and reflection, multi-channel analysis of surface waves (MASW), downhole, and passive seismic surveys for geohazard assessment, environmental monitoring and research.
MEGA Philippines provides seismic refraction, seismic reflection, multichannel analysis of surface waves (MASW), downhole, and passive seismic survey services for site investigation, foundation design, fault characterization, and geohazard assessment across the Philippines. We measure both P-wave (compressional) and S-wave (shear) velocities using multiple survey methods — giving structural engineers and geotechnical professionals the complete subsurface parameters they need for NSCP seismic design requirements.
The Philippines sits on the Pacific Ring of Fire, with active faults crossing major urban and industrial zones. Seismic surveys are essential for high-rise buildings, industrial facilities, dam foundations, and any structure where site-specific ground motion parameters are required for safe design. Our multi-method approach ensures the right technique is selected for your project’s specific depth targets, site conditions, and budget — whether a quick MASW for Vs30 determination or a full passive seismic program for deep fault characterization.
