Precisely, this earthquake evokes the last ones engraved in the collective memory of Mexicans, not only because of the level of damage generated but also because, by a terrible coincidence, all three occurred on 19 September, in 1985, 2017, and 2022. All three caused the loss of lives and extensive damage to property, buildings, and infrastructure. All three had a magnitude greater than 7.0. Fortunately, none of the three occurred during the night. Therefore, all of us, absolutely all of us who lived through them, remember precisely what we were doing in each of those three earthquakes. In my case, in 2017, I was in Guadalajara preparing to participate in the SMIS Seismic Engineering Congress; how ironic. In 2022, working from home in Mexico City, a Monday that looked like the beginning of a quiet week turned into several weeks of building assessments.

As a civil engineer focused on structures, living in a country where at least one earthquake with a magnitude greater than 6.0 [1] occurs every year means constantly thinking about the impact of my profession on my daily environment and my family and friends. In this context, anything with a roof over represents a higher risk of collapse just because it is located in CDMX, compared to other cities. However, this risk can be reduced by applying engineering provisions that allow the structural elements supporting the roof to withstand the forces generated by an earthquake.

Despite knowing all this, it is inevitable not to feel anguish in those few seconds when determining if the abnormal movement is a simple dizziness or if it really is an earthquake. Once it is known that it is an earthquake, we Mexicans are trained to activate the reflex to move from under the roof above us because consciously -or unconsciously, most of the time- we think it will come down on us. The reality is that fewer and fewer buildings collapse. In Mexico, in 1985 there were around 400; in 2017, there were 38, and none in 2022. In the same way, fewer and fewer people are dying: 3192 officially in 1985 [2] (although 20 thousand are estimated), 369 in 2017 [3] , and 1 in 2022 [4]. These figures imply a journey in the right direction, although it is also acknowledged that the goal has not been reached.

Although it is practically impossible for a structure not to suffer any type of damage during its useful life, today, there is technology that allows buildings to be less damaged and the contents and users to be less affected. For example, elements such as base isolators can reduce the movement transmitted from the ground to the structure. The application of these devices is becoming more and more common, and it will soon be that someone inside one of these buildings will definitely feel safer inside than outside.

In any case, the deficiencies evident in the recent earthquakes in Turkey and Syria reminded me of a phrase often used by a professor: “No one has ever seen the strongest earthquake”. Not only in Mexico we do know that another earthquake will come at any moment, but as users, taking out property insurance is an option that allows us to mitigate the financial risk of damage to our property.

Without giving it too much thought, I studied engineering with the intent to design bridges, and life has led me to apply my knowledge today to the forensic evaluation of structures once an incident has occurred. I have had the opportunity to assess several buildings affected by earthquakes. In some cases, the damage was superficial, such as cracks in the cladding materials, while in other cases, a comprehensive restructuring was essential. I find it exciting to develop in this sector, and it is also satisfying to participate in projects whose objective is the reinstatement of damage to people’s property.

From CDMX, I am at your disposal to attend to any claim associated with damage to structures and supported by DAC’s international team, we can cover any region in the world.
