Analysis of a global database on quaternary explosive volcanism (2009)
Presentation / Conference
Ortiz Guerrero, N., Sparks, R., & Hobbs, L. (2009, December). Analysis of a global database on quaternary explosive volcanism. Poster presented at AGU Fall Meeting 2009, San Francisco, USA

Large volcanic eruptions, despite their low frequency of occurrence, have the potential to cause massive loss of life and affect the health of humans and animals and cause major economic losses. The knowledge of the evolution of past volcanic process... Read More about Analysis of a global database on quaternary explosive volcanism.

Partitioning of SO2 between dacitic melt and aqueous fluid phases (2009)
Presentation / Conference
Hobbs, L., & Keppler, H. (2009, June). Partitioning of SO2 between dacitic melt and aqueous fluid phases

Sulphur dioxide has significant effects on global climate. By combining with atmospheric water molecules to form H2SO4 aerosols, which strongly backscatter sunlight, it can cause a potentially global net reduction in temperature following a large exp...

HCl molecules emitted from volcanoes breakdown to form chlorine free radicals via heterogeneous chemical reactions and photolysis, which act as catalysts to the breakdown of ozone in the stratosphere. Ozone depletion of up to 2-7% was estimated follo... Read More about Adsorption of HCl onto volcanic ash.
