September 19 in Mexico City: the stadium-safety lesson football has not fully learned

On September 19, 2026, millions of Mexico City residents will leave metro stations, subway cars, Metrobús buses, and Cablebús cable-car cabins under a hypothetical scenario: a magnitude 7.7 earthquake with its epicenter in Tehuacán, Puebla. This is the country's second national drill of the year, and it does not test the rails. It tests something the eye cannot see: human reflexes at the moment the ground beneath them stops standing still.

What caught my attention was not the number 7.7. It was the choice of date. Mexico rehearses on the anniversary of two earthquakes burned deep into its collective memory: 2026 and 2026. There, memory is not nostalgia. It is a component of the safety system.

For someone who tracks how systems operate, a story that seems to sit outside football lands exactly on what interests me most: managing a stream of people in an enclosed space under maximum pressure.

Mexico City is no stranger to the beautiful game. Estadio Azteca — where Pelé lifted the trophy in 2026 and Diego Maradona rewrote history in 2026 — sits only a few kilometers from the stations in the drill scenario. The city is built on a dried lakebed of soft soil, making buildings shake far more violently than on rocky ground. The earthquake of September 19, 2026, magnitude 8.0, killed thousands and flattened countless structures. A year later, Mexico still hosted the 2026 World Cup — a decision still cited today as proof of a nation's endurance.

The Metro, Metrobús, and Cablebús systems carry millions of passengers daily. When the ground shakes, underground stations and elevated cabins become the two most dangerous blind spots. That is why this drill does not teach people how to run. It teaches them how not to run.

Reading the 27 instructions in the scenario, I see a very clear operating philosophy: in a crowded system, the greatest enemy is not the shaking — it is disorganized panic.

The scenario asks passengers to stay calm, not to run, shout, or push. Not to cross the yellow line. To move away from platform edges and glass panels, toward the center or the wall. If you are inside a train car when the shaking begins, stay in the car, hold on, never use the emergency lever, and never force the doors open. Evacuation, if it happens, unfolds only under the coordination of station staff.

That philosophy has a name: move by instruction, not by instinct. On a stadium terrace, as on a platform, the human instinct in danger is to sprint toward the nearest exit. But in an enclosed space with thousands of people, that very instinct is the most dangerous thing there is.

Football history has recorded this in blood. The 2026 Hillsborough disaster in Sheffield — where 97 supporters died — did not begin with fire or smoke. It began with a stream of people compressed into a narrow tunnel with no one directing them. By contrast, many modern stadiums in Japan — where I live and work — can evacuate tens of thousands of spectators in minutes, not because Japanese people have better instincts, but because they are taught the reason behind every step.

This is where I want to stop. The Japanese are not strong because of discipline; they are strong because they understand why discipline is necessary.

I call it soft discipline — discipline that comes not from the whip or the command, but from each individual understanding why they must do the right thing. A Mexico City station can put up as many signs as it likes, and it will still not match a single passenger understanding that staying put inside the train is to protect themselves, not to obey an employee's order.

Applied to a concrete scenario: when a train stops between two stations, the instruction is clear that passengers must remain in the car, hold on, not use the emergency lever, and not open the doors. To an ordinary passenger, this is counterintuitive. Instinct says get out. The system says stay. The system is right — because the most dangerous gap in an earthquake incident is not between two stations. It is between individual will and the crowd around you.

With Cablebús, the cable-car system, the scenario is even more complex. The protocol splits into three tiers: automatic stop when an alert triggers, gradual stop when there is no alert, and finally a vertical rescue protocol to bring people out of elevated cabins. These three tiers show that the operator distinguishes very clearly between having a signal and having none. This is the kind of thinking I call designing for the unforeseeable.

But this is where I want to push back a little. There is a gap no scenario touches: the distance between the discipline of the transit system and the operating culture of the stadium.

The paradox is this: a transit system can reach near-perfect precision in a drill, because subway passengers are an emotionally neutral stream of people. They are rushed, they are tired, but they are not in a state of extreme euphoria.

A stadium is entirely different. When the final whistle blows after a tense derby, the crowd is no longer a stream of people. It is an emotional organism. And emotion — as I keep saying — is a variable inside the system, not something standing outside it. You cannot set emotion aside and tell yourself your system remains intact.

The Mexico City scenario teaches people not to run, not to shout, not to push. But teaching someone commuting at eight in the morning is far easier than teaching a supporter who has just watched their team lose in the 90th minute. That is the gap stadium organizers — not station managers — must answer for themselves.

In the tactical language I am used to, this is a design problem, not a willpower problem. Position is only the starting point; the system decides the destination. How many exits a stadium is built with, how wide the corridors are, how its staff are trained — all of these are variables of the system, not of instinct.

In many countries, crowd control at stadiums is handed to short-term contract staff, while subway station employees are properly trained in disaster response. That asymmetry is worth thinking about. An earthquake does not distinguish between a passenger waiting for a train and a supporter mid-chant. But how they react when the ground shakes is decided by entirely different systems.

The September 19 drill will be over within hours. The rails will run again, the cable cars will operate as usual. But the lesson lasts longer: safety is not a procedure; it is a habit measured by whether you can stay calm when everything around you is not.

For football, the question remains open. If an earthquake struck mid-second-half at Estadio Azteca, with eighty thousand people at their emotional peak — do we have a protocol as good as the one Mexico City has prepared for its subway? I am no prophet. I only read the data before the current changes course. And the data so far shows we have only rehearsed evacuating a happy crowd — never a panicking one.
