DESCRIPTION: Determine the source mechanism for Love waves in the seismic wave background. Field data analysis shows evidence that these waves are present, but current theory does not account for their generation. Objective 2: Determine the energy ratio of Love waves to Rayleigh waves for the horizontal components. This step could improve results from previous studies, including the monitoring of volcanic activity and fault systems. Objective 3: Determine the characteristics of the seismic wave background recorded on horizontal components, which could be used to illuminate other portions of the Earth. Love waves travel close to the surface and could be used in the study of subsurface processes, such as those that operate in volcanic systems.
