Evidence of VLP volcanic tremor in the band [0.2-0.5] Hz at Stromboli volcano, Italy
We analyze time series of Strombolian volcanic tremor recorded with a network of broadband seismic stations. We evidence the occurrence of a significant component of volcanic tremor in the range [0.2-0.5] Hz by using linear and nonlinear methods. The polarization and ZLCC analysis show that the wave field is characterized by high apparent velocity
