The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Friday January 24, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

The volcano has remained in a quiet state over the last 24 hours with very few rockfall signals, however there has been four major volcano - tectonic earthquake swarms in the reporting period.

There have been well over 100 earthquakes in these swarms with the latest one happening between 3 and 5 am this morning. These VT's usually show that magma is trying to reach the surface from shallow depths below the surface of the crater. In addition there was a flash flood in the Fort Ghaut area this morning.

The results of the COSPEC measurement (to show how much gas is in the atmosphere) made early in the week were made available yesterday (Thursday) and showed a value of 1260 tonnes per day. This is higher than normal but is expected after a collapse of the dome as we had on Monday night.

Both yesterday and this morning (Friday) the dome has been covered in cloud making the observations difficult. However from the seismic records it shows that the dome is still growing and that further collapses will occur in the near future.

The alert remains at ORANGE and all residents are urged to remain vigilant at all times and listen to ZJB Radio.
