Ancient Pyramid in Mexico Collapses Due to Extreme Weather and Rising Sea Levels

Extreme Weather and Climate Change Threaten Ancient Mexican Pyramid

On July 29, 2024, a 15-meter high stone pyramid in Ihuatzio, Michoacán, Mexico, collapsed due to extreme weather and relentless rainfall. This pyramid was part of the ancient Purépecha civilization, known for being the only empire that resisted the Aztecs.

The collapse revealed serious damage to at least six structures at the archaeological site, including walls and support systems. The National Institute of Anthropology and History (INAH) attributed the collapse to unprecedented weather conditions. The region faced heavy rain after enduring 30 years of severe drought, which created cracks in the pyramid and allowed water to seep in.

INAH stated that high temperatures and prior drought conditions weakened the structure. As a result, the pyramid’s integrity suffered, leading to its eventual collapse. The archaeological site, home to other significant monuments and tombs, is now a focus for restoration efforts to protect Mexico’s cultural heritage.

Recent climate studies highlight the risk to cultural sites globally due to rising sea levels and extreme weather. Similar effects have been observed with ancient rock paintings in Oceania becoming damaged from rapid climate change. This issue underscores the impact of human activities on historical sites.

Amid these events, a member of the Purépecha community interpreted the pyramid’s failure as a bad omen, reflecting a historical belief that such events signal displeasure from the gods. In the same week as the pyramid’s collapse, Utah’s iconic Double Arch also fell, likely due to erosion and changing water levels.

Heritage sites like these are invaluable. Their loss due to climate change is a poignant reminder of the urgent need for action to preserve cultural history for future generations.
