Another headline screams about a tragic death toll after a magnitude 7.4 earthquake rattles western Colombia. The media plays its favorite tape. Shocking videos of crumbling masonry, breathless anchors talking about the fury of the earth, and an implicit invitation to view the disaster as an act of angry gods.
It is lazy journalism at its finest.
Nature does not kill people in earthquakes. Bad construction does. When a 7.4-magnitude tremor strikes with a depth of over 100 kilometers, pointing the finger entirely at tectonic plates lets municipal planners, corrupt contractors, and outdated building codes off the hook. We need to stop treating structural collapses as unavoidable tragedies and start treating them as preventable failures of engineering.
The Geography of Blame
Let us look at the data instead of the panic. The United States Geological Survey placed the epicenter near San José del Palmar in the Chocó region, hitting at a depth of roughly 107 kilometers. Because of that depth, the energy dispersion over distance should have heavily mitigated localized surface devastation. Yet cities like Pereira, Manizales, and parts of Valle del Cauca saw buildings pancake.
Why? Because structural vulnerability is unevenly distributed by wealth and municipal neglect.
When media outlets compile casualty numbers, they frame the event as a sudden lottery of fate. Imagine a scenario where two buildings face the exact same peak ground acceleration. One stands because it adheres to strict seismic reinforcement standards. The other collapses into rubble because it was built with substandard concrete and zero shear walls.
The earthquake didn't choose which building to destroy. Human choices decades prior made that selection.
The Myth of Unpredictable Destruction
The lazy consensus in disaster reporting is that sudden seismic events override human preparation. Seismology tells a different story. Countries sitting on high-risk subduction zones, such as Japan or Chile, routinely absorb massive tectonic releases with minimal loss of life because their infrastructure is engineered to bend, isolate, and absorb shockwaves.
In contrast, large swaths of Latin America still rely on masonry that crumbles under horizontal shear stress. Municipalities routinely fail to enforce strict building codes, prioritizing short-term construction savings over human lives. When a tremor hits, the resulting catastrophe is treated as an unpredictable act of nature rather than a predictable audit of civil engineering failure.
Every time we accept "natural disaster" as the primary explanation for a collapsed roof, we excuse the regulatory bodies that signed off on substandard permits. We excuse the developers who cut corners on steel reinforcement bars.
What Actually Works
If we want to stop writing these exact same articles every few years, we have to shift the focus from emergency response theater to mandatory structural retrofitting.
- Enforce Seismic Microzonation: Cities must map local soil types precisely. Soft soils amplify seismic waves exponentially, yet builders routinely use standard blueprints across wildly different ground compositions.
- Mandatory Retrofitting Funds: Instead of pouring all capital into post-disaster relief funds, governments must subsidize structural retrofitting for aging brick and unreinforced masonry buildings before the ground moves.
- Prosecute Code Violations: Treat structural failure resulting from corner-cutting criminal negligence, not bad luck.
Stop watching the videos of collapsing facades and asking how nature could be so cruel. Ask why the human beings responsible for the concrete allowed it to fail.
