Mt. Pelee eruption 1902
May 8th a few hours after the eruption of St.Vincent, Mt. Pelee erupted on Martinique Island killing about 30,000 people. It was one of the most destuctive volcanic eruptions in history

la soufriere 1979
in a 1971 eruption, an island formed in the middle of a lake which filled a crater, causing la soufriere to erupt. thankfully, due to to advance warning there were no casualties and no fatilities
Why do volcanos erupt?
Convection currents are formed while magma gets pushed up through a weakness in the earths surface and becomes lava. it cools and over time gets pushed down into the mantel to restart the prosess.
The Dangers
La Soufrière is the youngest volcano on the island. it stands at 4,049 ft. The death zone, where almost all persons were killed in the last eruption, was close to entirely Carib. If it were to erupt it would be dangerous and cause masive destruction.
How do we know if it's going to erupt?
Soufriere is actually situated in the caldera of the dormant Qualibou volcano, also known as La Soufriere Volcano. It shows no signs of erupting but might erupt in the future. The signs it would show if it were to erupt would include small earthquakes beneath the volcano increased emission of heat and gas
How can we stay safe?
La Soufiere is a dormant volcano inside of a caldara. Mt.Pelee is an active volcano. Wear a emergancy mask over your face or a damp cloth and long pants and sleeves.
