A 1 cm diameter particle from an eruption of a volcano has been found at Site 1, located 30 km downwind of a volcano. Use the simulations below to determine the most likely combination of plume height and wind speed during the eruption. Place the mouse over the plume height buttons to generate particle trajectories for a suite of different wind speeds.
Record your answers in your field notebook.
Select a plume height to view transport of a 1 cm diameter particle.
Note: wind speeds are given in meters per second (m/s) on the particle trajectories
