In recent decades, the population exposed to volcanic eruptions has doubled, reaching one billion people. This alarming figure reveals a paradox: despite the history of destruction, humans continue to populate high geological risk areas. Urban planning and emergency management cannot rely solely on traditional maps. This is where 3D technology emerges as a fundamental tool for prevention and informed decision-making, allowing the visualization of danger in a way never before possible.
Modeling and simulation: digital tools to predict disasters 🔬
The core of this preventive revolution lies in the creation of digital twins of the terrain. From LIDAR and photogrammetry data, extremely precise 3D topographic models are generated. On these, volcanologists can run physical simulations of lava flows, pyroclastic clouds, and lahars. These models calculate speed, reach, and impact, accurately defining the highest risk zones. For urban planning, this means being able to assess the risk of a new residential development. For emergency teams, it allows designing optimal evacuation routes and locating shelters in safe areas, all tested virtually before a crisis occurs.
Visualize to raise awareness: the educational power of virtual reality 🥽
3D technology transcends the technical realm to become a powerful communication tool. A static model does not convey the immediacy of danger, but an immersive virtual reality simulation does. Showing authorities and communities how a lava flow would advance down their main street has a profound educational impact. This tangible visualization is key to fostering a culture of risk, justifying land use restrictions and ensuring that the population understands and respects evacuation plans, transforming data into understanding and action.
