including National Aeronautics and Space Administration (NASA)’s Tropical Rainfall
Measuring Mission (TRMM), reported that 500 millimeters of heavy rainfall fell on that area in a 10-day
period (Lagmay et al., 2006). The need to develop more effective spatial coverage of landslide
susceptibility and real-time hazard monitoring for vulnerable countries and remote areas remains apparent
and urgent (Sidle and Ochiai, 2006).
