There has been a partial dome collapse on the west side of the Soufriere
Hills Volcano.



The collapse started at 11:27 pm local time on Monday 28th July 2008
without any precursory activity. Part of the western side of the lava
dome collapsed generating pyroclastic flows that reached Plymouth and
the sea.



There were also a few explosions from the dome during the collapse, with
the largest at approximately 11:32 pm.



The height of the ash column was estimated at 12 kilometres (40,000
feet) above sea level.
