Daily Report
Report for the period 5 p.m. 5 June
to 5 p.m. 6 June 1998

The volcano has remained quiet today. Between 4 p.m. yesterday and 4 p.m. today 2 volcano-tectonic earthquakes and 3 rockfall signals triggered the seismic network.

The temperatures of the pyroclastic flow deposits in Plymouth were measured today. Near where the flows pass Lover's Lane the temperature was 212 degrees Centigrade at 2 meters depth. Near to the port the temperature at 2 meters depth was 163 degrees Centigrade while the temperature at only 20 centimetres depth was 91 degrees.

A record number of GPS stations were deployed last night with eight instruments recording simultaneously. GPS data show that the shortening of the line between Harris and Hermitage, which has been going on since last year, decreased greatly in recent weeks.

Dust levels were low at all sites today. A substantial blue haze of sulphur-dioxide gas was observed over Chances Peak this afternoon.

Residents are reminded that the volcano remains in a potentially active state, and that they should continue listening to Radio Montserrat in case there are sudden changes.
