HYDRO-METEOROLOGICAL HAZARDS ASSESSMENT
HAZARD ASSESSMENT EXPLANATION AND RECOMMENDATION
Areas with low susceptibility to floods are likely to experience flood heights of
less than 0.5 meters and/or flood duration of less than 1 day. These include
low hills and gentle slopes that have sparse to moderate drainage density.
Low Susceptibility; less
than 0.5 meters flood The implementation of appropriate mitigation measures as deemed necessary
Flood
height and/or less than 1 by project engineers and LGU building officials is recommended for areas that
day flooding are susceptible to various flood depths. Site-specific studies including the
assessment for other types of hazards should also be conducted to address
potential foundation problems.
Note:
All hazard assessments are based on the available susceptibility maps and the coordinates of the user’s selected location.
The possibility of both rain-induced landslide and flooding occurring is not disregarded. Because of the composite nature
of MGB’s 1:10,000-scale Rain-induced Landslide and Flood Susceptibility Maps, it spatially prioritizes the more frequently
occurring and most damaging hazards in an area. Continuous updating is being done.

HYDRO-METEOROLOGICAL HAZARDS ASSESSMENT
HAZARD ASSESSMENT EXPLANATION AND RECOMMENDATION
A storm surge (“daluyong ng bagyo”) is the abnormal rise in sea level that occurs
during tropical cyclones or “bagyo”. It happens when a very strong tropical cyclone
blows-off excessive amounts of seawater toward low-lying coastal communities.
It is catastrophic and life-threatening because a storm surge can cause massive
Storm Surge Safe inland flooding, sometimes in unimaginable heights. It is even more dangerous
when the storm surge coincides with a high tide.
For storm surge-prone communities, the most important considerations are 1) the
strength of the tropical cyclone, 2) the height of the surge, and 3) if the community
is located in a low-lying areas.
The Regional Severe Wind Hazard Map represents the 3-second peak gust wind
speed measured at 10-meter height (above ground) over open and flat terrain. This
does not take into account the local factors such as topography, terrain roughness
and shielding from neighbouring structures.
The Regional Severe Wind Hazard is expressed in terms of Return Periods (RPs)
of Tropical Cyclone winds. Return period means the repeat interval, or the estimate
of likelihood and severity of severe wind event. Return periods are then translated
into Annual Exceedance Probabilities (AEPs) which are the chance that a given
117.1 - 220 kph (20- severe wind hazard level will be equalled or exceeded in any year.
year return period);
Severe Wind At higher return periods, the wind speeds are stronger but are less frequent.
117.1 - 220 kph (500-
year return period) At lower return periods, the wind speeds are less intense but are more frequent.
The Regional severe wind hazard maps are used to update the wind zoning map of
the Philippines and as reference in designing building structures.
For those areas identified as high risk to wind damage, building codes/regulations
must be strictly implemented to mitigate severe wind risks. For already developed
areas, retrofitting is encouraged – the methods applied in this study can be used to
set out a cost-benefit study for retrofitting older, more vulnerable building types to
increase their resilience to severe winds.
