This Friday at noon, Jalisco will join Mexico’s Second National drill. Along the coast, loudspeakers will sound, and Puerto Vallarta will run a tsunami evacuation to test timing, routes, and coordination. South Coast towns will hear a preventive alert only. Phones will also buzz as the country trials cell-broadcast messages. The goal is simple and profound: practice now so we react faster later. If you live, work, or vacation near the beach, here’s what to expect and why it matters.
On Friday, September 19 at 12:00 p.m., loudspeakers along Jalisco’s coast will sound as part of the Second National Macro-Drill. In Puerto Vallarta and the North Coast, authorities will activate a tsunami alert and carry out a preventive evacuation to test routes and timing. In the South Coast, officials will run a preventive alert only, with no evacuations planned. The state’s Civil Protection agency frames the exercise as a way to strengthen self-protection and measure how well agencies and residents respond together.
The national drill runs at the same time across the country and invites public and private sites to register and participate. Organizers set the start for noon Central Time and ask participants to follow local guidance. The point is to practice the plan you would use in a real emergency, not to improvise one in the moment.
Along Jalisco’s shoreline, the Tsunami and Tropical Cyclone Warning System will broadcast pre-recorded messages through coastal loudspeakers positioned in key beach areas. The network has been used and maintained for years to warn beach communities of coastal risks. Friday’s activation is a drill. If you hear the message at noon, follow instructions calmly and look for staff and signage guiding you uphill and inland.
Puerto Vallarta earthquake drill
This year’s national drill adds something new: a test of cell-broadcast alerts that send a distinct tone and message to compatible phones, without needing data or credit. Traditional sirens and media will still carry alerts, but many residents may notice their phones buzzing too. It’s a step meant to reach more people, faster, when time counts. The drill is scheduled for noon, and registration for participating sites was set to close one day prior.
Jalisco’s working scenario assumes a powerful offshore quake near Chamela, driven by the Rivera plate. In that hypothesis, a tsunami pushes ashore in minutes, which is why coastal towns practice quick, orderly evacuations to mapped high-ground points. Puerto Vallarta, Cabo Corrientes, Tomatlán, La Huerta, and Cihuatlán are among the municipalities that would face the brunt of a real event. Drills like this measure how fast people move, how well routes work, and where communication breaks down.
What coastal residents will experience
If you’re in Puerto Vallarta or the North Coast at noon, you’ll hear the sirens and an evacuation order. Staff will direct people along marked routes to safe meeting points above the inundation line. Businesses and schools are part of the exercise. Expect traffic control near beach corridors and patient, steady movement uphill. If you’re on the South Coast, you’ll hear only a preventive alert as part of the protocol; no evacuations are planned there.
Treat the drill like game day. Keep your phone on, follow the audio instructions, and move calmly. Know at least one route to higher ground if you spend time near the beach. If you manage a business, ensure that visitors are aware of the designated areas and who to contact. The state will collect participation reports and evidence after the exercise to issue certificates and refine plans. That review process is as vital as the siren itself.
The drill takes place in a season when coastal alerts are no longer hypothetical. Jalisco’s authorities recently maintained a preventive tsunami posture after a distant major quake prompted federal monitoring. It’s a reminder that the system is active year-round and that clear instructions can arrive with little notice. Friday’s practice aims to make those minutes count.
In plain terms, Jalisco macro drill 2025 is not about alarm for its own sake. It’s about muscle memory. If a real quake or storm threatens, the goal is simple: hear the alert, move fast, help your neighbor, and meet where it’s safe. Practice gets us there.
