A second home spends most of the year empty. That changes the hazard calculation: nobody moves the furniture, nobody clears the drain, and nobody notices for weeks. Here is what to screen before you buy one.
Island provinces in the middle of the country sit directly in the path of storms crossing from the Pacific toward the west. Here is what to screen for a Marinduque or Romblon address, including the parts a hazard map cannot cover.
The southwest monsoon soaks the west side of the country. The northeast monsoon does the same to the east side, months later, and it rarely gets discussed when people buy property. Here is what that means for an address.
Butuan sits near the mouth of the Agusan River, at the end of one of the largest river basins in the country. For a buyer there, the flood conversation is about what happens upstream. Here is what to screen.
Inherited property comes with decisions: keep it, build on it, rent it, or sell it. Each one is easier with a clear picture of the hazards, and family memory of the land is usually incomplete. Here is where to start.
Outside Baguio, Benguet is steep country where the hazard conversation is about slope, cut-and-fill, and access. Here is what a hazard screening checks for a Benguet address and what you have to verify on site.
PHIVOLCS raised a lahar advisory for Pinatubo on 29 August 2026 as the enhanced habagat kept pouring on Zambales, Tarlac, and Pampanga. Here is what continued rain actually changes on the ground, which river systems carry the risk, and how to read your own address against it.
A hazard report tells you what the maps say. A site visit during heavy rain tells you what the ground does. Here is the list of things worth looking at while it is actually raining, and the questions to ask after.
Catanduanes sits alone off the Bicol coast, facing the open Pacific. Storms arrive there before they reach anywhere else in Luzon. Here is what a hazard screening checks for a Catanduanes address, and what it cannot tell you.
Two lots on the same street, 40 meters apart, can come back with different flood levels or elevations. That is usually the data working correctly, not a glitch. Here is what actually changes between two nearby points.
Sorsogon sits at the tip of Luzon with water on three sides and Bulusan Volcano in the middle. That gives a buyer three separate hazard conversations instead of one. Here is what to screen before you commit.
Repairs are the one moment you can change how the house sits on the land. Before you rebuild the same floor at the same level, here is what the hazard layers can tell you about whether this was a rare event or a recurring one.
