| Mt. Etna -- Mt Etna is a transitional shield-to-stratovolcano in northeastern Sicily. As viewed from this false-colored LandSat image, grey to black lava flows emanate from the volcano's summit area across vegetated regions at lower elevations, which show up in red. Note that the flanks of Mt. Etna are littered with parasitic scoria cones. Mt. Etna has exhibited several eruptive styles from effusive to explosive; strombolian eruptions are particularly common. It has erupted lava flows more than 150 times in recorded history (since 1500 B.C.). In 1979 small-to-moderate explosive eruptions killed nine people. It's most recent eruption was in January 2003. |
