Fig. 6From: Transport of ballistic projectiles during the 2015 Aso Strombolian eruptionsEstimated gas flow velocities. The drag coefficient values range from 0.62 to 1.01 and represent the measured drag coefficient based on experiments that were conducted with the ballistic projectiles of Popocatépetl volcano (Alatorre-Ibargüengoitia and DelgadoGranados 2006)Back to article page
