Several infrastructures in the Philippines are located in areas that are highly vulnerable to geohazards. In performing site-specific assessment of the susceptibility of infrastructures to these hazards and in turn, reducing the risk they pose to lives and property, the field of geoinformatics proves to be particularly valuable. Because of advances in geoinformatics, such as Light Detection and Ranging (LiDAR) technology and aerial photography, better data for geohazard assessment have become accessible. With the refinement of available geoinformatics data, previously unrecognized features such as scars of old landslides, gullies, erosion, and quaternary faults, which are indicators of how prone a site is to geohazards, can now be easily detected. This paper presents the usage of geoinformatics tools particularly LiDAR, satellite imagery, and drone photography, for a rapid geohazard assessment of an earthquake-prone area containing critical infrastructure.
