The Montserrat Volcano Observatory reports that 16 October saw high levels of activity at Soufrière Hills volcano, with several large pyroclastic flows descending to the south and further moderate-sized pyroclastic flows taking place towards the north-east. These flows are clearly products of instability and collapses associated with the growth of a new dome. Activity declined at around 17:00 local time on 16 October, and the MVO reports that things have been quieter today, although rockfalls and pyroclastic flow signals have been occurring cyclically every 2.5-3 hours.
Yesterday’s activity produced ash plumes that rose to a maximum height of 20000 feet or 6000 metres, as reported by Washington VAAC (advisory 20091016/1905Z). Today ash has been reported between 10000 and 16000 feet, 3000-4800 metres. The ash cloud has resulted in flight cancellations and diversions between Luis Muñoz Marín airport on Puerto Rico and various destinations in the United States and the Caribbean.
