There was an explosion at 6:40 yesterday evening. This was associated with pyroclastic flows down Gages, Tuitt's Ghaut and the Tar River Valley. The ash from this event reached approximately 15,000 feet and drifted north causing prolonged ashfall throughout the north of the island. Seismicity has been at a low level since the explosion.
Further explosions are expected and, although these will probably be similar in size to those experienced already, longer explosions fuelling more vigorous pyroclastic flows are a distinct possibility. There has been little seismic activity before the last few explosions and no warning is expected before further events. All residents remaining in Frith, 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 roads are very ashy this morning and drivers should be very careful. The wearing of ash masks is recommended at all times. Everyone is advised to keep listening to Radio Montserrat for information on the activity.
