Recent landslides, escarpments and tension cracks are present. Human initiated effects could be an aggravating factor. High landslide susceptibility Areas usually with steep to very steep slopes and underlain by weak materials. Areas with numerous old/inactive landslides. Moderate landslide susceptibility Areas with moderately steep slopes. Soil creep and other indications of possible landslide occurrence are present. Low landslide susceptibility Gently sloping areas with no identified landslide. Debris flow / Possible accumulation zone Areas that could be affected by landslide debris.

These areas are immediately flooded during heavy rains of several hours; include landforms of topographic lows such as active river channels, abandoned river channels and area along river banks; also prone to flashfloods. High flood susceptibility Areas likely to experience flood heights of greater than 1 up to 2 meters and/or flood duration of more than 3 days. These areas are immediately flooded during heavy rains of several hours; include landforms of topographic lows such as active river channels, abandoned river channels and area along river banks; also prone to flashfloods. Moderate flood susceptibility Areas likely to experience flood heights of greater than 0.5m up to 1 meter and/or flood duration of 1 to 3 days. These areas are subject to widespread inundation during prolonged and extensive heavy rainfall or extreme weather condition. Fluvial terraces, alluvial fans, and infilled valleys are areas moderately subjected to flooding. 8°30'0"N 8°30'0"N 126°3'0"E 126°4'0"E 126°5'0"E 126°6'0"E Low flood susceptibility Areas likely to experience flood heights of 0.5 meter or less and/or flood duration of less than 1 day.
