Color Image of Mt. Etna taken on July 13, 2001 | With
a thick air of ash, residents of Catania, Sicily, have been forced to use umbrellas
while walking outside thanks to the active Mt. Etna. After two days of relative
calm, most crews are cutting back their presence in the area according to news
reports. In the meantime, the local airport has been closed and a state of emergency
declared. The following images show the area on July 13, the first day of the
eruptions, and July 29, marking what experts hope is close to the end of Etna's
activities.

of Sicily, southwest of mainland Italy. The first image was captured by the Moderate
Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra spacecraft at
250-meter resolution. It dissolves into a true color image of Etna on July 13,
then July 29 as seen by the Landsat spacecraft at 15-meter resolution. CLICK

views in true and false color (Images 1-4), each revealing different features
of Etna's activities. The first image (Images 1 and 3)shows Etna on July 13 in
false then true color; the latter can take away much of the smoke and better show
the lava, etc. The second image (Images 2 and 4) shows Etna on July 29 in both
false and true color. The Landsat 7 spacecraft, a joint mission of NASA and the
United States Geological Survey (USGS) captured both views.
