Bubble Bursting in Mud Volcanoes
We are conducting laboratory experiments to study bubble dynamics in natural mud sampled from mud volcanoes near the Salton Sea in Southern California. Gas bubbles bursting at the muds free surface exhibit unusual behavior: bubble films first rupture away from the bubble apex, and often rupture at multiple locations simultaneously. I will use a high-speed video camera to measure features of multiple bubble bursts, and a cone-plate rheometer to characterize the muds rheology. Based on the experimental observations, I will formulate a simple physical model that can be used to numerically replicate observed bursting behavior. A successful model may be extended to other mud volcanoes, as well as magmatic volcanoes such as Stromboli, Italy.
