We analyzed continuous seismic records from a temporary network of 21 broadband seismograph that we installed in Gorely volcano (Kamchatka, Russia) between August 2013 and August 2014. During the studied period, the activity of Gorely was characterized by a sustained gas emission. We developed a source scanning algorithm based on summation of seismogram envelopes to automatically detect seismic events characterized by emerging signals without clear arrivals of P or S waves. With the help of this method, we detected and located numerous events originated from the vicinity of the main crater and caused by the volcano degassing. We then studied variations in spatio-temporal distribution of this seismic emission to characterize the evolution of the volcanic activity.
