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...

Volume calculations for Maar- Diatreme Experimental data
15 Aug 2012 | Contributor(s): Manoranjan Majji, Greg A Valentine
Using the partial point clouds obtained from stereoscopic images (point clouds are uploaded as a separate resource), we estimate the volume of the three main explosions using judicious approximations on the geometry of the Maar emulation in each case. University at Buffalo

Maar Diatreme Experiments - 3D point cloud data of three explosions
14 Aug 2012 | 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...

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...
