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
Get to know CVO: Alex and Infrasound
At the Cascades Volcano Observatory, staff use technical skills and creativity to solve complex problems and innovate for the future. Alex Iezzi uses sound waves to monitor volcanoes for eruptions and mass movements.

Get to know CVO: Maciej Obryk and the USGS debris-flow flume
At the Cascades Volcano Observatory, staff use technical skills and creativity to solve complex problems and innovate for the future. Maciej’s experiments are too large for the observatory, so he travels 3 hours southeast of CVO to the HJ Andrews Experimental Forest in Blue River, Oregon to study debris flows. Another important aspect of these flume experiments is that scientists can deploy instruments (like infrasound, laser rangefinders and seismic sensors) to see if they can detect the incoming flows. Next week we will meet two more scientists working to help prepare communities west of Mount Rainier for future lahars by
