text: Outgassed ash clouds extend up into the upper troposphere and into the lower stratosphere, also known as the UTLS; the height at which the volcanic plume reaches depends on the pressure within the volcanoes conduit tube and, as mentioned previously, depends on the amount of silica and oxygen within the magma (Krotkov, 2010).
