A 1 cm diameter particle from an eruption of a volcano has been found at Site 1 located 30 kms downwind. Use the simulations below to determine the most likely combination of plume height and windspeed during the eruption. Place the mouse over the plume height buttons to generate particle trajectories for a suite of different windspeeds. Note your answer 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
