Our experiments involved inducing crack propagation in gelatin by injecting a finite volume of air, with a camera capturing the crack shape, trajectory, and velocity. Sixteen high-frequency accelerometers on the gelatin surface recorded the resulting seismic signals. The propagation of the crack produced several events characterized by relatively low frequencies within the crack.
Objectives/Hypothesis:
The source of the seismic signal during magma propagation could stem from fracturing at the crack tip, closing of the tail, or fluid resonance within the fracture.
