CLUSTER FLOOD-REPORT-COASTAL · 7 ENTRIES · EARLIEST ENTRY 2026-08-20

Flood reporting and risk apps

This cluster consists of crowdsourced flood reporting, monitoring, and risk-alert apps serving regions such as Brazil and Pakistan. The dated history is too thin to read a shape from, as only four entries predate the index start. Traction leaders are Abhaya, floodsense-demo, and halsquad, each with zero stars but the highest activity signals in the cluster.

Entry timeline

ENTRY TIMELINE

AUG 2026: 1SEP 2026: 6
AUG 2026SEP 2026

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 7 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
