Summary: | Distributed Acoustic Sensing (DAS) has been an emerging technology on assessing
seismic wave for the past two decades. The high-resolution representation of the
wavefield in both space and time will be exploited to further study the ambient noise
that is distributed around the Stromboli volcano. Approximately 1 ???????? of fiber-optic
cable was deployed on the Northeastern flank at September 2020. The dispersion
curve of group and phase velocity obtained by the time-frequency stack of the cross
correlation of the ambient noise will be inverted to obtain the shallow structure of
the volcano. In this study, two distinguished area around the fiber optic cable are
characterized showing different phase velocities. Shallow subsurface structure on
the two area is obtained from the inversion and shows a high accordance with the
previous study. This result inferred new insights of DAS potential on recording
seismic signals and volcano monitoring |
