Hi Chris, Often that type of signal is due to wind noise. No sustained volcanic tremor has been detected at Iliamna during this recent episode of unrest. -Janet -------- Chris Browning wrote: I was just curious about the signal on the webicorder today (3/29) where the signal goes from quiet to a very even vibration almost like a constant tremor. Cant find anything on your help page that shows anything similar.
