Abstract: The sources of ambient seismic noise are extensively studied both to better understand their influence on ambient noise tomography and related techniques, and to infer constraints on their excitation mechanisms. Here we develop a gradient-based… read more here.

Abstract: The Earth's hum is the continuous oscillations of the Earth at frequencies between 2 and 20mHz in the absence of earthquakes. The hum strongest signal consists mainly of surface waves. These seismic waves can be… read more here.
