Longest continuously erupting volcano
Mt Stromboli
Italy (Tyrrhenian Sea)

Mt Stromboli, in the Tyrrhenian Sea off the coast of Italy, has been undergoing continuous volcanic eruptions since at least the 7th century BC, when its activity was recorded by Greek colonists. Its regular mild explosions of gas and lava - usually several each hour, have led it to be known as the 'Lighthouse of the Mediterranean'.
