Abstract
Frames of experiment N58 synchronized with the traces shown in Figure 6. From left to right, the two panels depict the traces trimmed in the 0.38 s–
0.53 s, 0.425 s–0.5 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 amplitude at S7 and are plotted in the y-axes as the location of its corresponding sensor along the HPA, distinguished in colors. The second panel depicts sustained low amplitude tremor associated with mass flux. See section 6 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 the laboratory. Such processes are correlated with the elasto-acoustic signals generated during the rock fragmentation, fluid-filled cavities formation, and mass-flux dynamics.
