I dived in Montserrat in
October 2005. The diving had to be arranged way ahead of
time with a private boat owner. It was very unique diving
there in face of the volcano eruption of 1995 that
killed 23 people and buried the capital city of Plymouth, the
old airport and the only hospital in the island. Underwater
visibility was around 15 meters and water temperature was 29°C. Diving
there is still not very safe, as after several months of quiet, a major
collapse of the lava dome of Soufrière Hills took place on 28 July
2008; part of the lava dome collapsed generating pyroclastic flows that
reached Plymouth and the sea, with the height of the ash
column estimated at 12 km above sea level.
