Iceland ’s Fagradalsfjall volcano erupted in 2021 after 800 years of dormancy.

Scientists built dams and diversion barriers from locally available materials like soil and volcanic gravel.

The largest dam delayed lava advancement by up to 16 days , while diversion barriers successfully redirected flows away from vulnerable areas.

From Hawaii to Italy , the techniques refined in Iceland could help protect lives, homes, and critical infrastructure from nature’s most powerful forces.

In a world increasingly shaped by climate instability and natural hazards, these simple yet effective barriers remind us that sometimes the most powerful solutions are also the most elemental.
