Experimental approach to constrain phreatic eruption processes on White Island, New Zealand (IAVCEI 2013 poster presentation)
06 Aug 2013 | Contributor(s): Klaus Mayer, Betty Scheu, Yan Lavallee, Ben Kennedy, H. Albert Gilg, Michael Heap, Mark Letham, Cristian Montanaro, Laura Jacquemard, Noemie Pernin, Donald D. Dingwell
White Island is New Zealand's most active volcano and primarily characterised by phreatic and phreatomagmatic eruptions. A phreatic eruption on August 2nd, 2012 ended an eleven year quiescence. More than 100 years ofintense hydrothermal activity from magmatic fluids and groundwater has created a...

Experimental constraints on magma mixing: case studies from Phlegrean Fields and Montserrat
30 Apr 2013 | Contributor(s): Daniele Morgavi, Diego Perugini, Bettina Scheu, Cristina P. De Campos, Donald B. Dingwell
The mixing process in nature is observed at different scales in the rock record, evident through variable structural and textural patterns and morphologies such as filament-like structures, enclaves, and mineral phases showing physico-chemical disequilibrium. The type and geometry of these...

Eyjafjallajokull ash cloud height comparisons
03 Sep 2010 | Miscellaneous | Contributor(s): Michael Pavolonis
The ash cloud heights retrieved using the GOES-R methodology (IR method) are compared to CALIPSO cloud boundaries inferred from the total attenuated backscatter. Ash clouds were identified by matching the CALIOP lidar data to SEVIRI infrared measurements. These are cases where the ash cloud was...
