See verified sinkholes before the next response gap.

SinkAlert is Bangkok’s multi-hazard ops shell: verified news incidents, open hazard feeds, GISTDA flood overlay, and LINE/web citizen reporting — without fabricated predictive risk scores.

Built on free & open Thai data — Sentinel-1, DMR, TMD, OpenStreetMap.

The problem

Underground risk is discovered too late

Road collapse can't be judged from the surface alone. Voids form silently under soft Bangkok clay — and today, inspection usually starts only after visible damage.

Hidden voids

Underground cavities are hard to detect and early warning is limited. By the time cracks appear, failure may be imminent.

Reactive inspection

Agencies inspect after collapse, not before. With thousands of km of road, they need to know where to look first.

Costly disruption

Emergency repairs shut roads and utilities, hurting businesses and communities — at many times the cost of prevention.

The solution

Open signals, verified incidents, agency playbooks

SinkAlert fuses open hazard feeds, a verified news incident catalog, citizen reports (VPS), and MHEWS SOPs — without inventing predictive risk scores until a published model ships.
