The separation of volcanic ash and sulfur dioxide (SO 2 ) gas is sometimes observed during volcanic eruptions. The exact conditions under which separation occurs are not fully understood but the phenomenon is of importance because of the effects volcanic emissions have on aviation, on the environmen...
