Description:
Here we present the data records (raw data) from 19 fragmentation experiments. In these runs silicic HVR254 dome rock (retrieved from the submarine Havre volcano) was crushed, remelted and fragmented using two different experimental settings:
1. dry runs (records labelled "D"): melt was fragmented by injection of pressurized Ar gas.
2. induced fuel-coolant interaction runs (records labelled "IFCI"): a water layer was established on top of the melt, before gas was injected from below. This caused fragmentation of the melt plug under IFCI conditions.
Note that the runs D07, D08, D09, IFCI08 and IFCI09 used a reduced melt mass (100g instead of 250g).
Files contain (separated by column) records of: time, trigger signal, force, pressure, microphone, electric field, seismic data.
The units and amplification settings used are provided in the file headers.
In addition, the results of morphometry analysis (t-tests) are provided in a pdf file. The morphometric analyses of natural ash focused exclusively on the curvi-planar grains dominant in Havre ash samples, labelled "Nat1" - "Nat6".
Four types of experimental grains were compared with them:
• “DG”: particles from dry runs, from the lab floor
• “IG”: grains from open IFCI runs, from the lab floor
• “IW”: very small particles from open IFCI runs deposited in water droplets on the walls and ceiling around the experimental area
• “IU”: particles from IFCI runs with U-tube, from the water bowl
