Over the past few decades, earthquakes have repeatedly demonstrated their devastating power. From the catastrophic tremors in Haiti (2010) and Nepal (2015) to the more recent disasters in Turkey and Syria (2023), seismic events have caused irreparable loss of life and infrastructure. While earthquakes themselves are natural phenomena beyond human control, the extent of destruction often stems from inadequate engineering and poor preparedness. This raises a crucial question: Why, in an era of space exploration and AI-driven advancements, do we still struggle to make our buildings truly earthquake-resistant?

Why Do Buildings Collapse?
- Poor Structural Integrity– Many urban centers still rely on outdated construction techniques that ignore seismic risks. Some countries lack stringent building codes, while others fail to enforce them effectively.
- Substandard Materials– Low-grade cement, weak steel reinforcement, and improper soil analysis exacerbate vulnerabilities under seismic stress.
- Modern Skyscraper Risks– While innovative, asymmetrical high-rise designs can be hazardous in seismic zones. The distribution of mass and stiffness critically impacts a building’s stability during tremors.
Lessons from Ancient Engineering
Remarkably, many ancient structures—such as the Pyramids of Egypt, the Taj Mahal, and Qutub Minar—have withstood centuries of seismic activity. Their resilience lies in:
- Wide-base designs (Pyramids) for stability.
- Deep-well foundations (Taj Mahal) act as shock absorbers.
- Tapered structures (Qutub Minar) ensure balanced load distribution.
These historical marvels highlight how sustainable, resilient construction techniques—without modern technology—can endure earthquakes. Perhaps we should revisit these time-tested methods in our pursuit of earthquake-resistant buildings today.
