Abstract
Frames of the fragmentation time window from 0.399 to 0.403 s of experiment N57 synchronized with the traces shown in Figure 9. This video shows details of the fracture development, and the signals generated during the fragmentation process in N57. Shaded areas indicate the time-window of gas ejection; accumulated between the diaphragms (green), and between the lower diaphragm and the sample (blue). The colored and numbered curves splitting into two indicate the fracture aperture. Overlapping the fractures curves are the velocity records registered at S2, S3 and S4. The fractures curves are plotted along the y-axes as they occur, and the signals are plotted as the location of its corresponding sensor along the HPA. The blue line between panels indicates the time phases interval and the red asterisks indicate the aperture time of each diaphragm. For more details see section 7.1.
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.
