Volcanoes are some of the most powerful forces on Earth, capable of reshaping entire landscapes in hours. But in rare cases, engineers and scientists have attempted something extraordinary: redirecting molten lava flows to protect towns, infrastructure, and critical land. In this episode of Engineering Insights, we explore how humanity tries to intervene in one of nature’s most extreme environments.

This episode dives into volcanic engineering, geotechnical engineering, fluid dynamics, thermodynamics, heat transfer, geological hazards, emergency response systems, and volcanic monitoring technology. We examine how lava moves like an incredibly slow but unstoppable fluid, why temperature, viscosity, and terrain determine its path, and how barriers, cooling techniques, and earthworks have been used to slow or redirect flows in real-world event ...
