Italy, from the Alps to Mount Etna – March 30th, 2012

Italy - March 29th, 2012

Snow rests atop the peaks of the Alps, arching across northern Italy and its border with Switzerland, Germany and Austria. South of the mountains lies the valley of the River Po, home to important cities such as Milan (visible as a grey area in the full image), west of Lake Garda. Although the Apennines, the mountain chain that forms the backbone of the peninsula, are snow-free, some snow can be seen at the summit of Mount Etna, in Sicily.

Ash and Steam Released from Puyehue-Cordón Caulle Volcano

Chile and Argentina - March 7th, 2012

Chile’s Puyehue-Cordón Caulle volcano could be seen releasing ash and steam at the end of the first week of March, 2012. The Chilean National Service of Geology and Mining reported that the plume was 1.2 kilometers (3,900 feet) high, and extended 30 kilometers (19 miles) from the active vent.

Other effects of the eruption can also be observed. Immediately to the east of the volcanic complex is a dark brown area, thick with fallen ash fall that has killed much of the vegetation. Further east are several bright turquoise lakes whose milky color is caused by fine ash suspended in the water. Some lakes show evidence of floating ash and pumice.

Haze Over Northern Italy and Sediments Around Gargano Promontory

Italy - March 3rd, 2012

Sediments line the Adriatic coast of Italy, particularly around the Gargano Promontory. Gargano is a historical and geographical Italian sub-region situated in Apulia, consisting of a wide isolated mountain massif made of highland and several peaks and forming the backbone of the Gargano Promontory projecting into the Adriatic Sea.

Moving northwards, haze can be seen over the Po Valley in the upper left quadrant. The valley is a plain around the River Po that extends approximately 650 km (400 mi) in an east-west direction, with an area of 46,000 km² (17,756 mi²); it runs from the Western Alps to the Adriatic Sea.

Visible in the lower part of the image, on the island of Sicily, is Mount Etna, its peak capped with white snow. In the full image, some faint ash can be seen spreading eastward from the volcano’s caldera, as Etna recently erupted for the third time in 2012 (click here for an article on the recent eruption).

Mount Etna Erupts for Third Time in 2012, Italy – March 5th, 2012

Mount Etna - March 4th, 2012

Visible by the left edge of this image is Mount Etna, in Sicily, Italy. A white cloud of ash and steam can be seen spewing forth from the volcano, which is already erupting for the third time in 2012. Mount Etna is one of the most active volcanoes in the world and is in an almost constant state of activity.

Mount Etna is an active stratovolcano on the east coast of Sicily, close to Messina and Catania. It is the tallest active volcano in Europe, currently standing 3,329 m (10,922 ft) high, though this varies with summit eruptions; the mountain is 21 m (69 ft) higher than it was in 1981. Etna covers an area of 1,190 km² (460 sq mi) with a basal circumference of 140 km, making it by far the largest of the three active volcanoes in Italy.

Mounts Sumbing and Gede and the Dieng Volcanic Complex, Indonesia – February 29th, 2012

Indonesia - January 4th, 2012

This APM image shows several volcanoes on the island of Java, Indonesia. Visible near the bottom edge is Mount Sumbing or Gunung Sumbing, an active stratovolcano in Central Java, Indonesia, symmetrical with Sundoro. The only report of historical eruptions is from 1730. It has created a small phreatic crater at the summit.

Moving to the northwest of Mount Sumbing one comes to  Mount Gede, followed by the Dieng Volcanic Complex. The complex of volcanoes is located on the Dieng Plateau in the Central Java, Indonesia. The volcanic complex consists of two or more of stratovolcanoes, more than 20 small craters and Pleistocene-to-Holocene age volcanic cones.The Prahu stratovolcano was truncated by a large Pleistocene caldera and then filled by parasitic cones, lava domes and craters.
