| Abstract | During this survey a total of 52 earthquakes were recorded in 29 days of operation of a network, which consisted of four I-Hz seismometers. of the events were classified as near events on the basis of their S-P intervals. Earthquakes in this group had a magnitude less than 1.8, and a characteristic frequency spectrum with a peak between 10-20 Hz.Earthquakes occurred in swarms, but showed no relationship between their frequency of occurrence and water level change at Inferno Crater Lake. Despite a positive correlation between acoustic noise and water level being found in previous work, we did not observe any strong acoustic noise. |
