UP-NIGS, through the Leveraging InSAR for Observation and Modeling of Earthquake Generators (LInOG) Project, recently concluded a five-day InSAR training workshop for technical personnel from the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Held from June 1 to 5, 2026, participants learned the theoretical foundations and practical skills of handling and processing synthetic aperture radar (SAR) data, for use in monitoring ground movement related to tectonics and volcanism over time through a technique called interferometry, hence InSAR. They were introduced to SAR imaging principles, interferogram interpretation, time-series analysis, and the generation of analysis-ready products such as ground velocity maps and geocoded outputs.
By the end of the workshop, participants had gained practical experience in using InSAR tools for ground deformation monitoring and interpreting results in the context of Philippine geohazards.
This activity, the first of its kind held in the Philippines, is one of the major outputs of the LInOG Project, a two-year DOST-PCIEERD-funded research project that aims to develop a semi-automated workflow for processing Synthetic Aperture Radar (SAR) data into ground displacement maps. Through InSAR, the project aims to develop on monitoring system for ground deformation along major active fault systems in the Philippines, particularly segments of the Philippine Fault in central Luzon.
