Morning Report
Report for the period 16:00 07 April
to 07:00 08 April 1997
The current alert level is ORANGE


Volcanic activity has remained at a low level overnight. There have been a few small to moderate rockfalls and four small volcano-tectonic earthquakes detected by the seismic network. Two small pyroclastic flow signals were recorded at 03.58 am and 04.25 am.

The dome is crystal clear again this morning. There is a marked steam plume, with minor amounts of ash, being blown to the west.

Although the level of volcanic activity is low, recent observations of the dome show that a major collapse of the southern part of the dome could happen with little warning. The alert level remains at orange, and so there should be no visits to zones A and B and only limited, short visits to zone C. Daytime occupation only is permitted in zone D. People should listen for further updates of the situation from the MVO. For the time being people are advised to remain vigilant and to always wear an ash mask in dusty conditions. The Tar River and White River valleys are extremely dangerous, and should not be entered at any time.
