Main Information

LCI: PHL169151720

At 10:30 on February 17, 2006, a massive rock slide-debris avalanche was triggered by combined earthquakes-rainfalls impacts in the Southern Leyte Province, Philippine. The landslide with its volume about 20 million cubic meters occurred after 10-day period of heavy rainfalls and a minor earthquake (M 2.6). The rapid and long travelling movement mass buried Guinsaugon village in the town of Saint Bernard. As a result, the catastrophic disaster caused widespread damages to socio-economic infrastructures and claimed 1,126 people. This is the worst disaster hit Guinsaugon community. The collapsed slope has geologic features of weathered volcano-clastic rocks. The landslide mass moved from the slope and deposited on the flat area with a length about 4 km.
