Daily Report
Report for the period 6 pm 28 January
to 6 pm 29 January 1998

Today the volcano was slightly more active than it has been recently, with ash venting and a relatively large number of rockfall signals. Between 16:00 yesterday and 16:00 today there was 1 hybrid earthquake, 4 volcano-tectonic earthquakes and 122 rockfall signals. The rockfalls occurred throughout the day with no definite peaks in activity.

The ash venting continued all day with a plume remaining above the volcano at a height of approximately 2 km. Light ashfall was reported in Salem and Woodlands. Ash was also generated by the many small rockfalls observed going down the Galways side of the dome, but the majority of ash was the result of ash venting that continued whether rockfalls were occurring or not.

The volcano was unusually clear today and observations from the helicopter showed that the dome has grown considerably in the last four days, since it was last seen. The active face of the dome remains in the Galways area

Despite the ashfall dust levels at all monitoring stations remained low today.

People should remain alert and listen to Radio Montserrat for further information.
