About
Oscar Alegria is a pioneering volcanologist and unmanned aerial systems (UAS) specialist whose research bridges volcanology, atmospheric science, and robotics. His primary contributions center on the in situ observation and sampling of volcanic emissions using custom-designed unmanned aircraft, a field where he has been a trailblazer. Alegria’s landmark 2013 study, detailing NASA and UCR drone deployments at Turrialba Volcano in Costa Rica, remains a cornerstone of airborne volcanology, with 36 citations. This work demonstrated that UAS can safely and repeatedly sample hazardous, transient plumes—offering unprecedented, high-resolution data on gas composition and particle behavior that remote sensing alone cannot provide. By enabling direct measurements of sulfur dioxide, carbon dioxide, and ash, Alegria’s research has fundamentally improved eruption forecasting and our understanding of volcanic impacts on climate. His achievements include pioneering the use of lightweight, low-cost drones for extreme-environment research, a methodology now adopted globally. With a career defined by technical innovation and field courage, Alegria continues to shape how scientists study Earth’s most inaccessible volcanic processes.
