Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 18 April
to 07:00 19 April 1997
The current alert level is ORANGE


The volcano has been fairly quiet overnight, with activity restricted to occasional rockfalls and small pyroclastic flows, and a few earthquakes. Most of the earthquakes have been long-period, with a few hybrid earthquakes as well.

Visibility is poor so far because of low cloud over the crater. The wind is from the south-east, and so any ash that is produced today may fall in the safe zone.

Despite the apparent low level of activity, the volcano remains in an unstable state, with further dome growth in the southern region above the Galway's Wall. Another dome collapse with extensive pyroclastic flows in the White River is expected within the next week. Residents of Montserrat should remain alert, and listen to Radio Montserrat for further updates. Ash masks should be worn in ashy environments. Visits to zone C should be restricted to those that are essential. All of Zone A, which includes Long Ground and St Patrick's, is very dangerous and should not be entered under any circumstances.
