Nord Stream 1 + 2 — Sep 2022

On 26 September 2022, four leaks were detected on the Nord Stream 1 and Nord Stream 2 gas pipelines near Bornholm. Seismic stations recorded two underwater explosions: 00:03 UTC (magnitude 2.3, NS2 in Danish EEZ) and 17:03 UTC (magnitude 2.1, three more leaks across NS1/NS2 in Swedish + Danish EEZs). Investigators later traced the 50-foot sailing yacht Andromeda — chartered from Rostock on 6 September with forged passports — to Wiek and Christiansø within 12 nm of the explosion sites. Russian salvage vessels (SS-750, SB-123, Sibiryakov) had also operated in the area on 21–22 September.

Detector backtest

Live-detector backtest captured: no alerts fired against the replayed track. The pattern in this incident wasn't reachable by the current AIS-based detectors (e.g. yacht below carriage threshold).

The same anomaly detectors that run against live AIS were replayed over a curated reconstruction of this incident. The alerts above are what would have fired in real-time. See About for the methodology.

Sources

Data note: Coordinates of the four leaks are exact, from Wikipedia (DK + SE official statements). Andromeda track is hand-curated from German police investigation reporting. Pre-blast salvage flotilla activity is approximated.
