Video showing six hours of seismic data from seismic station TANO on Tanaga Volcano. The top panel shows the spectrogram, and below is the seismic data. The audio is the subaudible seismic signal mapped to the range of human hearing. Earthquakes are heard as "pops" and occur frequently during this time period. A lower frequency event is heard around 13:51 UTC (04:51 AK). Video created by David Fee and Liam Toney, UAFGI/AVO. To view video, click the "full res" link below to download the file.
