미국 — 녹색 지진(규모 5.6M, 깊이:14.926km) 22/05/2026 12:16 UTC, MMI III로 인해 소수 인명 피해 발생

Summary

Low-confidence signal — single-source seismic detection only, awaiting news corroboration. A magnitude 5.6 earthquake struck the United States on 22 May 2026 at a shallow depth (14.9 km), with intensity mapping to Modified Mercalli III (weak shaking, minor damage potential). Few people were reported in the affected zone, but location specificity is absent from available data.

Supply chain impact

• Cotton, rare earth elements, semiconductors, natural gas, and crude oil supply chains could experience disruption if production or transport infrastructure in the affected region sustains damage; however, the shallow depth and reported limited population exposure suggest localized rather than widespread facility impact.
• No named logistics chokepoints are mapped to this event, limiting ability to assess port, pipeline, or corridor-level consequences without geographic precision on epicenter location.
• Supply chain materiality depends on confirmation of whether affected infrastructure (refineries, processing plants, transport hubs) lies within the seismic zone; MMI III-level shaking typically causes minor structural stress rather than failure.

Watch points

• Confirmation of epicenter location and affected U.S. state(s) — this will clarify exposure to energy and semiconductor clusters.
• Damage reports from facility operators in cotton-growing, rare-earth processing, or natural gas/crude oil infrastructure zones, if any are nearby.
