Flood and landslide exposure for every Malaysian locality

7,748 localities scored 0–100 each year since 2020, a modelled flood corridor for a reported locality, and a tracker of the incidents behind the scores. Three products, one index.

Risk index

A physical risk index per locality, from flood and landslide frequency, severity and recency in the incident record. Search any place, compare districts, read the year-on-year change.

The risk map over the Klang Valley with Bukit Travers selected: locality polygons on the water ramp, the score panel reading 28.8, high, computed 2026-09-04, and the nearby incidents list — The risk map, 2026 index, Klang Valley, one locality selected. Every locality is a polygon on the ramp; the panel carries its score, the computed date and the incidents around it.

Flood extent

For a reported flood locality, the terrain corridor water is likeliest to follow — height above nearest drainage, grown from the report inside a 5 km fence. Modelled, not observed: it is a first-report hypothesis of where to look, shown beside an equal-area circle so the terrain has to earn its place.

Model hand-fabdem-v1, computed 2026-09-23

District	Reports modelled	Vs circle	Band	Recall
Bentong	73	1.85×	1.5–2.2	46%
Kota Belud	335	1.38×	1.1–1.8	7%
Penampang	214	1.37×	1.0–1.7	13%

Vs circle: catch rate against an equal-area circle at the same point, first report only. Band: the 5th to 95th percentile when the district's reports are resampled — the figure is only as firm as its band. Recall: share of the later reports the corridor contains. The other 19 districts scored did not meet the bar, so no corridor is drawn there.

The flood corridor page for one Penampang report: the terrain corridor painted in the water ramp beside the equal-area circle drawn as a dashed contour, with the panel reading 281 ha, a hypothesis, not an extent — One Penampang report, 2024-11-29, at 1.0 m assumed depth: the corridor follows the valley where the equal-area circle does not.

Disaster tracker

The incident record the index is scored from — floods, landslides, fires and earthquakes from JPS, JKR, JKM, NADMA and PRABN, plus signed-in field reports — searchable by place and date, with photographs where they exist.

The disaster tracker for 2026: year tabs and a place search over a map of Malaysia with incidents grouped into numbered ink circles, beside a panel of reported incidents by type and the latest reports — The tracker for the current year: incidents grouped on the map, totals by type and the newest reports beside it. Signed-in users add reports with a location, a source link and photographs.

How the index is computed

Sources. PRABN flood forecasting, JPS, JKR and JKM flood reports, NADMA disaster records and the JMG landslide database, mapped to 7,748 locality boundaries.

Score. Frequency, severity and recency of incidents in a rolling window, per hazard, combined into one 0–100 index and five ordinal bands.

Snapshot. Every score carries the date it was computed. A score is what the record showed on that day, not a forecast, and it is re-scored each year as the record grows.
