IMAGE 95311
AVO Image

Real-time seismic amplitude (RSAM) time series for Veniaminof seismic station VNWF, located on the lower southwestern flank of the caldera. Plot runs from June 2013 through December 2014 and shows the seismic energy release associated with 2013 eruption and the gradual decline in seismicity beginning in late October 2013. Several episodes of increased low-frequency events and tremor bursts occurred from mid-July to end of the year (e.g. July 15, Oct. 8, and Dec. 18); however, these were not associated with any eruptive activity and may have reflected continued degassing of the system.
