M 7.3 Earthquake Strikes Near Puerto Madero, Mexico — Operations Footprint at Risk

A magnitude 7.3 earthquake struck approximately 58 km WSW of Puerto Madero, Mexico, registering a maximum sentinel severity of 10.0. While the epicenter is in southern Chiapas near the Guatemalan border — distant from primary hub cities — earthquakes of this magnitude in Mexico can trigger cascading impacts including infrastructure damage, transportation disruption, and aftershock sequences that may affect worker mobility and site safety across the country. Operations leaders with Mexico-based contact-center, back-office, or knowledge-worker staff should verify site status, activate BCP check-ins for Chiapas and southern Mexico locations, and monitor for aftershocks or tsunami advisories that could broaden impact.

Why declaredmergeDeterministic
Incident dedup / merge keys (entity, episode, network, region+title)v2
Checked in order against open same-domain incidents (never an aggregate-titled bucket): (1) ENTITY key, region-independent, incident active <14d (updated_at): shared CVE id, OR (cyber) >=2 shared distinctive vendor/product tokens (1 suffices when it carries a digit, i.e. a product model), OR (travel, agents-039) same travel operator/system key (travelSystemKey — airline/ATC/GDS/rail identity with a disruption cue), OR same network/AS key (agents-022). (2) EPISODE key (weather/environmental/disaster + travel per agents-039), incident active <7d: same hazard family (weather: heat/tornado/flood/cyclone/winter/wildfire/storm; travel: strike/ground_stop/airspace/it_outage/transit) AND same macro-region (eu | us/<census region> | country code) — a multi-day strike series or rolling ground stop refreshes ONE incident, not dailies. (3) Legacy region-overlap + title-word dedup, active <24h (v5 unchanged). Merge unions affected_regions + related_signal_ids + material_event_keys, bumps event_count, advances the material clock, renders the merged regions into the description ("Affected regions:" trailer), logs stage=declare decision=merge (engine deterministic), and unions the evidence projection’s signal sources.

Why SEV3SEV3score 3Deterministic
Incident severity level (SEV1–SEV4) at declarationv2
Base: SEV2 if sev>=9 AND news>=2 AND bpo>=1; else SEV3 if sev>=8 AND (news>=1 OR bpo>=1); else SEV4. Acute severe-weather (agents-028): if sev>=9 floor to SEV3 (SEV2→SEV3); minor/transient watches+advisories drop SEV2/SEV3→SEV4. Single-event cap: any SEV2 caps to SEV3 absent sustained multi-day BPO-region corroboration (SEV2 promotion is human-gated via revalidation). Systemic-travel floor (agents-039): a travelSystemicFloor declaration (multi-signal aggregate on member-relevant geography, sev 6-7 by design) floors SEV4→SEV3 — a region-level operational disruption, same honesty argument as the acute-weather SEV3 floor. It never raises anything to SEV2: SEV2 keeps its base intensity+news+human gating. score = numeric SEV (1=most severe … 4); SEV3/SEV4 auto-validate, SEV1/SEV2 require human validation.
