Morning Report
Report for the period 6 pm 22 October
to 7 am 23 October 1997

There have been no explosions overnight. At 7,00 am this morning it was 36 hours since the last explosion but despite this long period of quiet residents are warned that more explosions are likely.

The volcano-tectonic earthquake swarm which began at about 8.00pm on 21st October continued until about 2.30am this morning. The swarm was not intense although it did contain some large earthquakes. Seismic activity has been low since the end of the swarm with only one or two small rockfall events triggering the seismic system.

Further explosions may occur with no warning. All residents remaining in Friths, Old Towne and Salem are thus urged to move out as soon as possible.

After an explosion, fallout can occur anywhere on the island. People should shelter in a strong building and wait for the fallout to end. If this is not possible then hard hats or other suitable protection should be worn. Avoid driving during or immediately after ashfall if at all possible. The wearing of ash masks is recommended in ashy conditions. Everyone is advised to keep listening to Radio Montserrat for information on the activity.
