Masbate island, Ticao and Burias sit in the middle of the archipelago with sea on every side. Here is what to screen at an exact address.
Masbate is three main islands, Masbate proper, Ticao, and Burias, sitting between Bicol, Samar, and the Visayas. There is open water on every side and nothing much sheltering any of it.
The province is often described as quieter than its neighbours in terms of direct hits. That is a statement about frequency, not about exposure, and the coastline here is long relative to the land area.
Masbate City, Mobo, Milagros, Aroroy, Cataingan, Placer, San Jacinto, Claveria and most other population centres are at or near the shore.
Read together:
Ticao and Burias are narrow islands with water on both sides, which means very little of either is far from a shoreline.
Masbate has rolling to hilly interior with short watercourses. Screen flood susceptibility and the distance to the nearest mapped waterway together.
As on other smaller islands, cross-check a blank or implausible waterway result against what you can see. Community-mapped data is thinner away from the main urban centres, and a coverage gap is not a clearance. The reasoning is in a layer came back blank on your report.
Aroroy and parts of the northwest have a long mining history. Disturbed ground, spoil, and old workings change how a slope drains and what material is available to move.
For any address on or below slope, read slope with mapped landslide susceptibility, and ask locally whether there is mining or quarrying history on or above the property. That is not a mapped layer and it is a real question. See quarrying, clearing, and the flooding downstream.
Central Philippine islands are not seismically quiet, and Masbate has experienced damaging earthquakes. Read the distance from your coordinates to the nearest mapped active fault as an input for a licensed structural engineer, alongside the liquefaction estimate for low, sandy coastal ground.
The reasoning on how to use a fault distance is in magnitude and intensity are two different numbers.
On island provinces, supply is the practical constraint. Ask where water comes from, what happens in the dry months, whether coastal wells go brackish, and how long power outages typically last after a storm.
Ferry connections matter for the same reason. Ask how often crossings are suspended and what happens during a medical emergency when they are.
A hazard screening reads public national datasets at a point and reports mapped susceptibility, elevation, slope, and distances. On smaller islands some community-mapped layers are thinner, and disturbed ground from mining is not mapped at all. Weight local knowledge, the MGB regional office, and a licensed geotechnical engineer accordingly.
CheckHazard does not replace a professional geotechnical or engineering survey.
