Natural Disaster Risk Profile
Earthquakes
The province lies within the Philippine Fault System. The major fault lines traverse the
municipalities of Sogod, Libagon and San Juan to Panaon Island. According to the Mines
and Geosciences Bureau (MGB), these areas experienced magnitude 6.9 earthquakes in
1907 and 1948 and magnitude 6.4 earthquake in July 1984.
Flood
The province has 18 major rivers. Of these, Subangdaku River in Sogod municipality is the
largest. Subang Daku has a very wide floodplain and becomes hazardous during heavy
rains. In 2001, the river overflowed, inundating low-lying towns of Liloan and San
Vicente and destroying then ongoing flood control project. The province also has an
inland lake, Lake Danao, located in the mountains of San Juan and Anahaw towns.
Natural Hazard Risks:
Southern Leyte is a province of the Philippines located in the Eastern Visayas
Region (Region VIII). Maasin City is the capital of the province. Sothern Leyte
ranks as the second least populated area in the region, but it is one of the
most disaster-prone areas in the country. The province’s geological features
and location render it vulnerable to a range of natural hazards, including
flooding, tsunamis, rain-induced landslides, earthquake hazards and storm
surges.

Density:
Approximate number of people (or percentage of the
total population) highly susceptible to natural hazards:
1. Flooding: 249,941 (or 64% of the total
population of the province)
2. Tsunami: 221,321 (57%)
3. Rain induced landslide: 214,640 (55%)
4. Earthquake hazard: 135,929 (35%)
5. Storm surge: 207,778 (53%)
Population Vulnerability Profile:
Landslide
The MGB has warned that province’s geological features make it susceptible to landslides and flooding.
In December 2003, a landslide in San Francisco municipality killed 200 people and destroyed most of the town.
In February 2006, Barangay Guinsaugon, Saint Bernard Municipality, was almost flattened due to a landslide,
which killed 1,800 of its 1,857 residents.

Vulnerability is the conditions determined by physical and environmental factors or processes, which increase the susceptibility of a community to the impact of
hazards. Risk is the probability of harmful consequences, or expected losses (deaths, injuries, property, economic activity disrupted) resulting from interactions
between natural hazards and vulnerable conditions. (Source: International Strategy for Disaster Reduction)
