No earthquake was located during the night. The Gages seismic station recorded several episodes of broadband tremor throughout the night at variable but lower amplitude levels than previously. The repetitive very small long period events have also continued to occur throughout the night and their amplitudes have also been variable. The rate of occurrence of these small events has increased to about 6-7 per minute and they are similar to those observed during episodes of dome growth. The broadband tremor is indicative of increased steam emission from the crater region. Several larger long-period events were also recorded. A signal typical of mudflow in Fort Ghaut was also recorded by the Gages seismograph at approximately 20:46 on December 16 and this would be due to heavy rainfall.
