Get to know CVO: David and D-Claw
At the Cascades Volcano Observatory, staff use technical skills and creativity to solve complex problems and innovate for the future. David uses algorithms to model different volcanic hazards to help emergency managers plan and prepare for eruptions. D-Claw is a revolutionary tool for hazard modeling because it creates a more realistic model of how flows behave by including solid-fluid feedbacks that occur during a flow. This enhancement improves previous modeling techniques and creates a more accurate picture of where the flows may go and how fast they will get there. The better the model, the more accurate and detailed information can
