Five primary earthquake hazards in the Philippines, with the authoritative source for each. BantayLindol does not redistribute PHIVOLCS / GeoRiskPH hazard rasters — for per-site reports we deep-link to HazardHunterPH so you always get the latest official layer.
Peak ground acceleration (PGA) and intensity contours for scenario earthquakes (e.g. West Valley Fault Big One M7.2). Visualized at the per-barangay level by PHIVOLCS GeoRiskPH.
