Out of thirty-six (36) rural barangays, 14 are exposed to 3 different types of hazards present in the locality. These hazards are flooding, tsunami and storm surge.
Flood occurs only in the Poblacion wherein households were constructed within the historical riverways along the Naguilian river bank. Also, House Construction was not regulated.
Landslide usually occurs along the Naguilian river and tributary creeks wherein its slope is more than 18% and soil formation is loose. These also happen in areas or mountains where slopesare more than 18% and where the soil is loose. The same was observed along roadsides with undulating slopes.
Flood: The Municipality is not a flood prone Municipality although on the report of the MGB Assessment, the following areas are susceptible to flooding:portions of Barangays Caoayan, Dalacdac, Old Poblacion, and Delles - barangays traversed by the Ribsuan river. Although there is no flooding reported, flashflood occurs in these areas during rainy season.
Landslides and Erosions: Since Burgos is located in a mountainous area, most of the Barangays in the Municipality experience moderate erosions and landslides. These erosions and landslides are concentrated in the mountainous and hilly portions of the municipality with very minimal forest cover.
Two thousand four hundred fifty (2,450.00) hectares of land equivalent to 80% of the total area of the Municipality are subject to severe erosion hence, categorized as protected land area. Since 45% of the area is the clay type the internal drainage is good but the external drainage is excessive. In the cultivated areas of the town excessive erosion is evident however, in the terrace hillside where rice is planted, erosion is minimal.
Flood: The Municipality of Naguilian which comprises 37 barangays is exposed to hydrometeorological hazards such as flooding, rain-induced landslide, and tension cracks triggered by strong typhoons, which bring heavy monsoon rains.

Most of the typhoons making landfall affect not only the Municipality of Naguilian, but also the whole Province of La Union.
For the last three censual years, flooding is the most common hazard that affects almost all barangays with high susceptibility to flooding.
Rain-Induced Landslide: The Municipality of Naguilian and the whole province of La Union is vulnerable to rain-induced landslides which are caused by forest denudation, lack of vegetation covers in steep areas and loose soil along riverbanks and creeks.
Population that is exposed and vulnerable to rain-induced landslide comprises of twenty-three (23) barangays mostly located near mountains and creeks.
