Montserrat Volcano Observatory

Daily Report
Report for the period 5 p.m. 5 July
to 5 p.m. 8 July 1998

Activity at the volcano during the past 24 hours has continued at about the same level as yesterday. 14 rockfall signals and 24 volcano-tectonic earthquakes were recorded.

The results of COSPEC measurements done yesterday indicated a sulphur dioxide flux of 2,100 tons/day. This figure is quite high compared to previous measurements but would need to be supported by further measurements before any firm conclusions can be drawn. Measurements would again be done tomorrow from the MV Shamrock II.

Ash levels today were low at St Johns, Salem, Old Towne and Woodlands. However roadside conditions remain in the alert level during and after the passage of motor vehicles. Ash masks are therefore strongly recommended when walking and driving in these areas.

Low cloud covered the volcano for the entire day and no views were obtained of the summit.

Residents should continue listening to Radio Montserrat in case there are more sudden developments in the state of the volcano.
