Bristol Island update 17/7/16

Since my last post (dated 18th June 2016) an ash plume or a plume with ash content originating from Bristol Island was visible in satellite images from various days, the most recent being on the 16th July 2016. During other days, sometimes the plume was white in colour and sometimes cloud cover prevented observations.

In my view:
a) The eruption which began during late April 2016 continues.
b) The volcano is going through a different eruptive phase consisting of continuous explosive eruptions.
c) A new eruption might be occurring although I think it's most likely one of the above two scenarios.
