MVO has been constantly monitoring the gas, ash, and acid aerosol emissions from the volcano. These emissions have already impacted severely upon vegetation on the western (downwind) flanks of the volcano. Monitoring of gas at particular levels and compositions as well as rain and groundwater is done to ensure the safety of the habitat of the capital, Plymouth, and surrounding villages to the west of the volcano.

The ash clouds have begun to
bury most of the currently evacuated town of Plymouth.
The emissions of dangerous gases have killed much of the vegetation and livestock in the nearby areas. Hazardous gases are constantly being vented from the Soufriere Hills volcano.
