Abstract
Frames of the experiment N57 synchronized with the traces shown in Figure 10. From left to right, the four panels depict the traces trimmed in the 0.38 s–0.52 s, 0.41 s – 0.5 s, 0.43 s – 0.44 s, 0.494 s – 0.497 s time ranges, respectively. As the video runs, a moving red line points to the time on the traces at its corresponding panel correlating the signals with the video (left panel). The signals are displacement records normalized with respect to the maximum displacement at S6 and are plotted along the yaxes as the location of its corresponding sensor along the HPA, distinguished in colors. The 2nd panel depict the same records, in the time window related to layers jam and block of the mass flux. Panels 3rd and 4th show a zoomed in of 2nd and 5th signals displayed in the 2nd panel, respectively. All signals are normalized with respect the maximum amplitude in S3. See sections 7 for details.
Description
The videos show the physical processes related to rock fragmentation and mass flux dynamics triggered by rapid decompression of volcanic samples in laboratory. Such processes are correlated with the elasto-acoustic signals generated during the rock fragmentation, fluid-filled cavities formation and mass-flux dynamics.
