Etna Erupts Again
Sicily's Mount Etna has
erupted again, with another series of strong explosions that broke the silence
of the towns surrounding the mountain.
However, experts monitoring the volcano said the ash pouring out of the crater
was diminishing.
Etna, which springs to life every few months, burst into activity on October 27
with rivers of lava pouring down the mountain near Catania in eastern Sicily and
columns of thick ash and smoke as much as two kilometres high.
During the eruption, Catania's airport was forced to shut down for several days,
but the current volcanic activity did not appear to threaten the airport or
roads in the area.
Several villages, whose residents work in tourism and in agriculture, dot the
slopes, but no town has been threatened by the recent eruption.
Mount Etna, Europe's highest at 2,700 metres, continues to spread ashes and
black smoke into the atmosphere.
Its magma is flowing southwards, again threatening the woods which were already
damaged by recent eruptions.

Magma is flying 100 metres in the air

Water-spraying planes and helicopters attempted to prevent the spread of forest fires and tremors continued to shake the area, following Sunday's eruption.
The airport outside the city of Catania remained closed for a second day.
There were no problems with inhabited areas, said regional president Nello Musumeci, although the tourist industry was in crisis.
The lava has swallowed buildings, including at least one restaurant, knocked down power lines and pushed over ski-lift pylons.

One stream of lava, six metres high, is pouring down the northern side of the volcano while the other is heading south.
Both Linguaglossa and the forest fires are located on the northern slopes.
Schools in Linguaglossa have been shut down, although the church has remained open for local people to pray.

In Catania, residents shielded themselves from falling ash.
The mayor banned motorbikes from the streets, because of the dangerous driving conditions.
Earlier, he moved to reassure Catania's 330,000 residents that they were in no danger, although some hotels have been evacuated.
Tremors galore
Europe's most active volcano has been throwing magma more than 100 metres (330 feet) in the air, in a spectacular display.
More than 200 tremors shook eastern Sicily on Sunday.
On Monday, one right under the volcano registered 3.8 on the Richter scale.
Mount Etna has had four major eruptions in the last 309 years. Vulcanologists have warned that it is gradually becoming more explosive and more dangerous.
Etna is almost constantly rumbling, but had not erupted since July and August last year, which experts described as one of the most erratic and complex displays in 300 years.
Its last major eruption was in 1992.
Satellite sees 200-mile ash, smoke plume from Mt. Etna
NASA-GSFC NEWS
RELEASE - Posted: October 30, 2002
New satellite pictures from NASA show the dark brown smoke and ash plume
originating from Mt. Etna stretching for hundreds of miles over the
Mediterranean Sea. The Moderate Resolution Imaging Spectroradiometer (MODIS)
instrument on NASA's Terra satellite captured a spectacular true-color images of
the eruption. A long, grayish-brown plume of ash and smoke is streaming
southward from the volcano.
Mount Etna - October 2002
Located on the island of Sicily, Etna is one of the most studied volcanoes on Earth. Just last summer, French scientists reported that Etna appeared to be undergoing a gradual shift from being a "hot spot" volcano, in which magma wells up from within the Earth, to an "island arc" volcano, in which magma is produced from the collision of tectonic plates. In keeping with that idea, this most recent eruption occurred after a series of hundreds of small earthquakes affected eastern Sicily. Unfortunately for area residents, the transition from a hot-spot volcano to a island-arc volcano signals the potential for greater danger, as the latter produces explosive, as opposed to oozing, eruptions.
