Global chokepoints

Chokepoints are places where local disruption can become global friction. Ports, canals, straits, border crossings, rail corridors, and energy transit routes concentrate movement into narrow physical or administrative paths. TremorWatch tracks these locations because a small operational issue in the wrong place can affect delivery schedules, freight rates, insurance assumptions, and sourcing decisions far beyond the immediate area.

The chokepoint score combines recent events with the strategic role of the location. A weather event near a minor port does not carry the same implication as a closure near a globally significant canal or strait. Likewise, a security incident may matter more when it occurs near a corridor used by energy, grain, containerized goods, or critical minerals.

These pages are intended for practical monitoring. A high-risk chokepoint should prompt readers to check carrier advisories, port authority updates, marine traffic patterns, customs notices, and supplier lead times. TremorWatch provides the context layer: what happened, where it happened, which routes or commodities could be connected, and why the event should or should not be escalated.
