From November 1995 to December 1997 a total volume of 246×106 (DRE) m3 of andesite magma erupted, partitioned into 93×106m3 of the dome, 125×106m3 of pyroelastic flow deposits and 28×106m3 of explosive ejecta. In the first 11 weeks magma discharge rate was low (0.5 m3/s). From February 1996 to May 1997 discharge rates have averaged 2.1 m3/s, but have fluctuated significantly and have increased with time. Three pulses lasting a few months can be recognised with discharge rates reaching 3 to 8 m3/s. Short term pulsations in growth lasting a few days reach discharge rates of over 10 m3/s and there are periods of days to a few weeks when dome growth is <0.5 m3/s. Discharge rate increased from May 1997 with an average rate of 7.5 m3/s to December 1997. The observations indicate an open magmatic system.
