There have been two explosions overnight, at 9:27 yesterday evening and 5:05 this morning. The explosion yesterday evening was followed by pyroclastic flows down the Gages Valley and across the Farrell's Plain. It produced an ash column which reached 18000 feet Due to cloud and darkness the explosion this morning was not observed. Seismic tremor as usual followed both explosions. In the case of the explosion this morning the ash venting that corresponds to this tremor was heard as a jetting noise as far north as the MVO.
Further explosions are anticipated today, although the interval between explosions is quite variable at the moment so it is difficult to know when the next one will be. Explosions could be bigger and thus more dangerous than they have been so far. 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 wearing of ash masks is recommended in ashy conditions. Everyone is advised to keep listening to Radio Montserrat for information on the activity.
