Phase 1: Airport Arrivals and Flight Advisory
Following the major earthquake, regional flight operations in southern Mexico may experience temporary delays as ground crews conduct runway inspections. Travelers arriving at Tapachula Airport (TAP) or nearby hubs in southern Mexico should verify flight statuses before heading to the airport. Minor trembles can occur after the main shock, so pay attention to local announcements.
For international visitors entering Mexico, ensure you keep your migration details handy. Make sure to activate a local cellular data plan or backup eSIM to receive immediate push alerts and notifications regarding evacuation zones from local civil protection authorities.
Phase 2: Transiting Safely Through City Commutes
Earthquakes can damage road infrastructure and disrupt traffic light networks in urban areas. If you are traveling through Chiapas or surrounding cities, be alert for cracked road surfaces, falling debris, or blocked lanes. Avoid using underpasses or older bridges until civil engineers have cleared them.
When booking transport, rely on local ride-hailing applications that display real-time road conditions and detours around emergency zones.
Phase 3: Postponing Regional Excursions and Road Warnings
Coastal excursions and marine activities near Puerto Madero should be suspended immediately due to active tsunami waves reaching up to 0.3 meters. The National Seismological Service of Mexico recommends staying away from beaches and coastal roads. Mountainous highway routes in Chiapas are also prone to landslides after major seismic activity; avoid intercity driving where possible.
Verify active highway advisories via the official federal police and civil protection communication channels.
Phase 4: Savoring Local Food and Dining Tipping While Sheltering
Sheltering in your hotel or a designated safe open space is the safest course of action during active aftershocks. If ordering food delivery while sheltering, please be patient as riders navigate traffic restrictions. Tipping delivery riders 10% to 15% is customary and highly appreciated in Mexico, especially during regional emergency operations.
Although mobile payments are common in tourist areas, local grid issues could temporarily disable card readers. Keeping physical Euro or Peso cash is recommended for emergency purchases.
