Two (2) earthquakes were located during the night at depths in the range 4-6 km and just south of St. George's Hill. These were volcano-tectonic events. The Gages seismic station continued to record broadband tremor throughout the night at variable amplitudes, with periods of lower amplitude revealing the continuous presence of repetitive very small long period events. The rate of occurrence of these small events is about 2-3 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 05:50 on December 16 and this would be due to heavy rainfall.
