One (1) volcano-tectonic earthquake was located overnight; this occurred at a depth of approximately 1.5 km, just north of St George's Hill. Nine (9) long-period events occurred which were recorded at most seismic stations. Several periods of low amplitude, broadband tremor were recorded by the Gages seismic station overnight; these were short in duration and not recorded elsewhere.
The level of seimicity continues to be consistent with moderate levels of steam production and very slow dome growth within English's Crater.
