Ruapehu - IGNS - Science Alert Bulletin V95/52

Sunday 22 October 1995
1600 hours NZDT (UT +13)
Ruapehu Volcanic Activity

Situation Summary

As of 1600 hours, the following information is available.

*     Seismic activity has remained at relatively low levels for the past
24 hours.  Activity at the Dome seismograph picked up at 1660 hrs
yesterday and has shown continuous but low activity since.  This
seismicity is not strong enough to affect either the Chateau or Ngauruhoe
stations, both of which have been very quiet.

*     Weather conditions have precluded observations for much of the day.
At c. 0900 hours there was reported a weak steam emission plume visible
from Whakapapa, but this plume did not appear to be carrying any
significant amounts of ash.  No other reports of activity have been
received, and no field parties have been operating due to the weather
conditions.

Conclusions and Alert Status

The present eruption episode is continuing at a reduced level, with
significant gas emissions.  We advise that the Alert Level remains at 3.
