Maar-diatremes - a course module
13 Jun 2016 | Contributor(s): Greg A Valentine, Alison Graettinger
Maar-diatremes are one of the most common volcanic landforms on Earth, and represent an end-member type of volcano whose eruptions are dominated by explosive, subsurface magma-water interaction. Thus they should form an important component of volcanology courses. The recent decade has...

Large Scale Experiments on Volcanic Processes (EOS)
19 Jul 2011 | Contributor(s): Greg A Valentine
Some of the least understood and most hazardous geologic processes involve complex multiphase flows, particularly those related to explosive volcanic eruptions. These phenomena inherently involve a wide range of characteristic length and time scales, as well as processes that are coupled across...

Videos of Test Blasts in preparation for the NSF Volcano Hazards Field-Scale Experiment Workshop, 2018, Buffalo
15 Jun 2018 | *Data Sets/Collections | Contributor(s): Ingo Sonder, Greg A Valentine, Andrew Harp
These test blasts were conducted in 2017, in preparation for the 2018 NSF Workshop on Volcano Hazards Field-Scale Experiments.For one event, six PETN charges (0.44 MJ energy each) were placed into prepared test beds ("pads"), made of unconsolidated crushed rock material. Charges...

Maar Diatreme Experiments - 3D point cloud data of three explosions
14 Aug 2012 | *Data Sets/Collections | Contributor(s): Manoranjan Majji, Greg A Valentine
During the Maar-Diatreme experiments conducted, we were able to extract useful 3D point data after three major explosions.The point set is hereby included for research purposes.In the current form, the data has NOT been aligned with the mean sea level(MSL). However, ROUGH estimates of the datum...
