In 1997 a previously long-dormant volcano on the Caribbean island of Montserrat erupted. In just a few minutes a fast-moving lava flow surged down the mountain covering a great swathe including the capital Plymouth. The lava was followed by mud slides and almost the whole of the south of the island was buried in a choking layer of ash. The residents of the capital and the affected parts of the island had been evacuated prior to the eruption. A great many lives were undoubtedly saved but 19 lives were still lost and everyone knew that life there would never be the same again. Twenty years after the eruption only 4,000 of the original population of 12,000 remain.
