ROME - A volcano on the Italian island of Stromboli erupted Wednesday, releasing hot trapped magma in a powerful explosion, killing one person and enveloping the popular tourist destination in ash, witnesses and local officials said.
The one fatality, believed to be a tourist, was killed by falling stones during a hike, a rescue service official said. A second person was injured.
Italian news agency ANSA says the blast sent about 30 tourists jumping into the sea for safety.
The unexpected eruption started fires on the western side of the small Mediterranean island, which lies north of Sicily, off the toe of Italy. Fire crews were being called in from nearby locations and a Canadair plane was already in action.

"We saw the explosion from the hotel. There was a loud roar," said Michela Favorito, who works in a hotel near Fico Grande, on the east side of the island.
"We plugged our ears and after this a cloud of ash swept over us. The whole sky is full of ash, a fairly large cloud," she told Reuters.
Fiona Carter, a British tourist on the island of Panarea, some 17 miles from Stromboli, heard the blast.
"We turned around to see a mushroom cloud coming from Stromboli. Everyone was in shock. Then red hot lava started running down the mountain towards the little village of Ginostra," she told Reuters.
"The cloud got bigger, white and gray. It enveloped Ginostra and now the cloud has covered Stromboli entirely. Several boats set off for Stromboli," she added.
Stefano Branca, an expert with the National Institute of Geophysics and Vulcanology (INGV), said there had been a "paroxysmal eruption" on the island, when high-pressure magma explodes from a shallow, underground reservoir.
"These are events of great intensity and quite rare," he told Reuters.
Tourists often climb to the 3,000-foot summit of the volcano and peer into its crater, with small puffs of molten rock regularly blasted into the sky. It was not clear if anyone was on the crater at the time of the blast.
