Makati is one of the most sought-after addresses in Metro Manila, but a high price tag is not a hazard map. Before you commit, here are the flood, fault, and liquefaction risks worth checking in the BGC neighbor everyone forgets to screen.
Makati carries one of the strongest brand names in Philippine real estate. It is a shorthand for stability, good infrastructure, and high resale demand. But a premium address is not a hazard certificate, and the same national data that flags other Metro Manila cities also covers Makati. Here is what to look at before you sign.
The logic goes: expensive area, well-maintained streets, no shanties near the creek, so no problem. That reasoning misses two things. First, hazards are tied to geography, not property values. A fault does not care what the lot costs. Second, Makati is not a single homogeneous block. It ranges from the Ayala central business district to older residential pockets near the Pasig River corridor and the hills of Guadalupe. The risk profile shifts depending on exactly where the property sits.
The safest-looking address can still carry exposure. Flood maps, fault traces, and liquefaction susceptibility layers are drawn from soil surveys and topographic data, not from the price per square meter. Checking the national data takes five minutes and costs far less than discovering the problem after you have moved in.
Makati is not uniformly flat. Some parts sit at higher elevation and drain reasonably well. Other areas, particularly those near the Pasig River and the tributary creeks that cut through older barangays, show flood susceptibility in national hazard data. During intense or prolonged rain, low-lying sections can accumulate water faster than the drainage network clears it.
What to look for:
The flood return period framework explains what the 5-year, 25-year, and 100-year flood maps actually mean. A property that shows low risk on the 5-year map may still appear on the 25-year map. Both are worth checking before a long-term purchase.
The West Valley Fault is the most consequential active fault in Metro Manila. Its trace runs along the eastern side of the metropolis, but ground shaking from a major rupture would be felt across the entire NCR, including Makati. Distance from the fault trace matters, but it is not the only variable. Soil type affects how shaking amplifies, and soft or alluvial soils can intensify ground motion even at moderate distances.
The West Valley Fault explainer covers how the fault works and what the government modeled for a worst-case rupture. If you are buying a high-rise condo in Makati, the structural engineering of the building and the soil conditions at the foundation matter as much as the fault's distance. A building on dense, stable soil behaves differently from one on softer fill.
Practical step: Check whether the building has undergone seismic retrofitting if it was constructed before the current National Structural Code edition. Ask the developer or HOA for documentation.
Liquefaction happens when saturated, loose soil loses its strength during an earthquake and behaves temporarily like a liquid. It is most likely in areas near rivers, former riverbeds, and reclaimed land. Parts of Makati near the Pasig River corridor, and some older districts built on filled ground, carry elevated liquefaction susceptibility in national screening data.
Liquefaction does not mean a building will necessarily collapse, but it can cause uneven settling, damage to foundations and underground utilities, and long-term structural issues. For a condominium, this risk sits partly with the developer's engineering decisions. For a house and lot, it affects your foundation directly.
Read more about how liquefaction susceptibility is assessed and why it is labeled an estimate in the liquefaction explainer. If a property shows elevated susceptibility, the next step is a site-specific geotechnical study, not avoidance.
Before you sign a reservation agreement or deed of sale, run through this list:
A CheckHazard report draws from national government datasets: PAGASA, PHIVOLCS, and MGB source data compiled at a resolution useful for property-level screening. What it cannot do is replicate a site-specific engineering study. It tells you which hazard layers intersect with an address and at what severity level. It does not model the behavior of a specific building on a specific soil profile under a specific event.
If your report flags meaningful exposure on more than one hazard layer, treat that as a prompt to commission a professional geotechnical or structural evaluation, not as a final answer. The ₱99 report is a starting point, and a fast one. A geotechnical survey is what comes next when the screening warrants it.
CheckHazard does not replace a professional geotechnical or engineering survey.
