The address-intelligence read every Filipino buyer deserves before they commit. Floods, faults, landslides, storm surges, translated into the call you'd defend at the bank, in front of family, on the way home.

◢ Precision intelligence
Every report runs your coordinates against these nine independent datasets, each maintained by a Philippine government agency or open-data project. Tap any layer to read its brief.
Will this property flood in the next typhoon, and how deep? Read against 5/25/100-year return periods so you know whether it's a normal-season risk or a once-a-generation event.
How close is the nearest fault to your future bedroom? The 5 m no-build setback isn't optional, and the 1 km advisory band changes the structural design your engineer must specify.
If the lot is on a slope (or near one), we surface what the soil and gradient could do under heavy rainfall. Sendong-type events still happen every year.
For coastal addresses: does the ocean reach the front door in a typical typhoon, or only in a once-in-a-generation super-storm? The SSA1-4 bands tell you which.
Soil that turns to liquid during shaking is the difference between a cracked wall and a tilted house. Flagged on every address when the proxies push past safe.
Creeks and esteros are the second-biggest reason Filipino homes flood. Named, distance-measured, and checked against the Water Code easement that bans construction.
How high above sea level. How steep the lot. Two numbers that quietly drive flood depth, drainage cost, and whether your foundation needs engineering you didn't budget for.
Some lots sit in the path of debris that flowed there during the last super-typhoon. We flag when MGB has mapped the parcel inside one of these zones. It changes the foundation conversation.
Within 10 km is the danger zone. 30 km gets ashfall during eruptions. 100 km affects insurance riders. Mayon, Taal, Pinatubo proximity belongs on every PH report.
◢ Sample report
CheckHazard generates a comprehensive hazard dossier for any Philippine address, accurate to the 10–50m geocoding bounds of Google’s street-level resolution.
Every threshold is named in the report: the 50-meter proximity buffer that catches edge-of-zone properties, the 5/25/100-year flood return periods tagged on each polygon, and the slope and elevation cutoffs behind every Low/Moderate/High verdict.
11 formulasSeven open-licensed PH datasets stitched together: UP NOAH flood, landslide, and storm-surge polygons; PHIVOLCS active faults and volcanoes; MGB-DENR geohazards; PSA NAMRIA admin boundaries; and OpenTopography SRTM 30-meter elevation rasters.
7 datasetsEach section opens with a How to read this intro so you don't need a planner or geologist to interpret the result. A Rating Guide at the back of every report explains the 5-level severity scale and the threshold bands behind each verdict.
10 sectionsBeyond the polygons, every report translates risk into action. Insurance Guidance maps each hazard to flood, earthquake, and volcano premium bands; Legal Constraints flags Water Code easements and PHIVOLCS fault buffers that affect what you can build; Historical Events compares your address to Ondoy 2009, Yolanda 2013, and Ulysses 2020 with measured inundation depths.

Bottom line
Elevated, well-drained ground keeps flood, landslide, and storm-surge exposure off this address. The composite rating is set by ~820 m proximity to the West Valley Fault, inside the PHIVOLCS strong-shaking band. Material disclosure for permits, structural design, and earthquake insurance pricing.

Plain English for the homebuyer reading on the bus home. Methodology disclosure for the LGU planner defending a permit decision at appeal. Tap a card to see how.
Before paying a reservation fee or signing a 20-year mortgage, see how the address compares to Ondoy 2009, Yolanda 2013, and Ulysses 2020, with measured flood depth, fault distance, and the insurance riders the property would trigger.
Cite the same UP NOAH polygons, PHIVOLCS faults, and MGB-DENR geohazards that DOST recognizes. Every threshold and buffer is named inside the report, so a permit clearance or denial holds up to citizen appeal.
◢ Inside a CheckHazard report
Google Places suggests as you type: partial inputs, misspellings, Filipino place names. Every address is geocoded once; revisits hit our cache, so the same lookup never costs you twice.
Floods, faults, landslides, storm surges, volcano proximity, slope, elevation. Cross-checked against the same authoritative datasets a licensed planner or underwriter would consult. Cited line by line in your report so you can defend the read in front of family, the bank, or the building official.
SELECT * FROM get_hazard_score(14.55, 121.05);A structured report with plain-English findings for every hazard layer: the composite rating, the full findings grid, legal constraints, insurance guidance, and methodology notes. Cited line by line. Saved to your dashboard so you can revisit anytime the questions come up later.
Every spatial query runs on our own PostGIS · flood · landslide · surge · fault · slope · elevation · 9 ms median
Read the ground before you sign. We translate every authoritative hazard layer into the plain-English read you'd actually use to decide. Saved to your dashboard so you can refer back when the questions come up later. ₱299 per address when the verdict needs to hold up.
