  • Farmland on the south of the island was destroyed
  • Roads blocked
  • 100-150 houses buried by hot pyroclastic surges
  • Destroyed W.H Bramble airport in 1997
  • Thick ash made it impossible to see roads
  • vehicles melted from intense heat
  • Flooding occured and valleys were blocked by ash
  • forest fires caused by pyroclastic flows

  • various organisations became involved in offering aid
  • British government is responsible for the support of £41 million of aid
  • Montserrat volcano observatory supplied a risk management zone map
