RESUMO
The catastrophic eruption of Mount Pinatubo on June 15, 1991 resulted in the monumental task of immediate damage assessment and monitoring, and the long-term mitigation measures including resettlement and rehabilitation, by the Philippine Government. However, the lack of accurate and timely information on the highly dynamic boundaries of the mudflow that characterized the desert-like "lahar-scape" of Central Luzon hampered such government plans. Aerial photography and satellite-based imagery acquired in the visible-infrared portions of the electromagnetic spectrum have provided basic information for the preparation of lahar-hazard maps. In addition, synthetic aperture radar (SAR) technology, both airborne and spaceborne, has been used to supplement the visible-infrared data for lahar damage assessment and monitoring. This study likewise examines a proposed model for monitoring lahar movement in relation to infraestructure activities
