Explosive eruption processes and their deposits

Session ID#: 162727

Session Description:
Explosive volcanic eruptions manifest a variety of behaviors over a range of length- and timescales, from discrete Strombolian explosions to sustained Plinian columns injecting ash, gas, and aerosols into the stratosphere to pyroclastic density currents depositing ash for tens of kilometers while generating co-ignimbrite ash plumes. These eruptions can also pose substantial hazards to proximal and distal life and property. Our understanding of explosive eruption processes is driven by direct observations of active eruptions, study of their deposits, analysis of pyroclasts, and analog and numerical experiments. This session welcomes contributions that broaden our understanding of explosive eruptions, the deposits they leave behind, and the parameters that control eruption style.
