Daily Report
Report for the period 6pm 10 May
to 6pm 11 May 1998

The level of volcanic activity has remained very low but seismic activity has been slightly elevated over the past 24 hours.

Between 4pm yesterday and 4pm today there were 20 volcano-tectonic earthquakes, one hybrid and 15 rockfall events recorded by the seismograph network. These latest VT's are located in the same place as most of the previous VT's over the past few weeks, that is about 2-3km directly below the dome.

Dust levels were low today. Yesterday evening and night there was a strong smell of sulphur over much of the island. This was caused by the very light winds from the south carrying gases off from the dome in an unusual direction. The dome has been giving off gas and steam continuously since it grew from late December through February, but these gases are usually carried out to sea to the west by normal wind conditions. Today, the wind direction has been from the southeast and sulphur smells in the north were not so widely experienced.

A visit was made to Brodericks today to look for a suitable location for a new seismograph station, and GPS surveying was continued on the island-wide network.

Residents are reminded that the volcano remains in a potentially active state, and that they should continue listening to Radio Montserrat in case the present quiet situation at the volcano changes suddenly.
