Saint Helens reawakens Hawaii's hot spots _______________________________________________ SICILIAN SMOKE A brown plume of smoke and ash streams southward for hundreds of miles from Sicily's Mount Etna on October 28.

Scientists think Europe's largest volcano is in a geologic transition from oozing eruptions to more explosive upheavals.

Eldfell ("fire mountain" in Icelandic) is a volcano on the island of Heimaey in the Vestmannaeyjar archipelago 15 miles (25 km) south of Iceland. In January of 1973, an eruption began along a 1.5 mile (2 km) long fissure not far from the center of the town of Vestmannaeyjar. The fissure extended across the entire island, producing a spectacular curtain of fire. Nearly all of the island's 5,300 residents were evacuated to the mainland.
