20/02/2018, volcano Sinabung, Sumatra Sinabung is a typical stratovolcano in northern Sumatra next to the town of Berastagi. There are no confirmed historic eruptions before the re-awakening in August 2010, but possibly it has had activity in around 1600 and 1881.
It is evident that Sinabung volcano has frequently erupted on its flanks producing lava flows. Sinabung has four overlapping summit craters, where fumaroles have been active, particularly in 1912, but no eruption followed the increase of fumarolic activity then. The 4 summit craters are aligned along a N-S direction. The youngest crater of this andesitic-to-dacitic volcano is at the southern end of the four overlapping summit craters. Authorities extended a danger zone around a rumbling volcano in western Indonesia after it spewed blistering gas farther than expected, sending panicked residents streaming down the sides of the mountain.

24/06/2016, Sjiveloetsj Kraj Kamtsjatka, Russia This 100 m image of 16 February 2017 shows us the volcano Sjiveloetsj, the northernmost active volcano in Kamchatka Krai, Russia. It and Karymsky are Kamchatka's largest and most active volcanoes. Shiveluch began forming about 60,000 to 70,000 years ago, and it has had at least 60 large eruptions.
The current active period started around 900 BC. Since then, the large and moderate eruptions has been following each other in 50 to 400 year-long intervals. Catastrophic eruptions took place in 1854 and 1956, when a large part of the lava dome collapsed and created a devastating debris avalanche.
06/07/2016, Mount Taranaki & Mount Ngarahoe, New Zealand The 100 m image of 11 September 2016 shows us Mount Taranaki & Mount Ngarahoe in New Zealand.
Mount Taranaki, or Mount Egmont, is an active but quiescent stratovolcano in the Taranaki region on the west coast of New Zealand's North Island. Although the mountain is more commonly referred to as Taranaki, it has two official names under the alternative names policy of the New Zealand Geographic Board. The 2,518 metres mountain is one of the most symmetrical volcanic cones in the world. There is a secondary cone, Fanthams Peak , 1,966 metres on the south side.
Mount Ngauruhoe is an active stratovolcano or composite cone in New Zealand, made from layers of lava and tephra.
01/01/2017, Kilimanjaro, Tanzania The right part of the 100 m image of 11 September 2016 shows us mount Kilimanjaro in Tanzania which is the highest mountain in Africa. The mountain is part of the Kilimanjaro National Park and is a major climbing destination, but also subject of many scientific studies because of its shrinking glaciers and disappearing ice fields.
Kilimanjaro is a large stratovolcano and is composed of three distinct volcanic cones: Kibo, the highest; Mawenzi at 5,149 metres and Shira, the shortest at 4,005 metres. Mawenzi and Shira are extinct, while Kibo is dormant and could erupt again.
11/09/2016, Cascade Range, USA The 100 m false-colour image of 11 September 2016 shows us the Cascade Range, a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains.
The Cascades are part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes.
The Cascade volcanoes define the Pacific Northwest section of the Ring of Fire, an array of volcanoes that rim the Pacific Ocean. The Ring of Fire is also known for its frequent earthquakes. The volcanoes and earthquakes arise from a common source: subduction.

18/05/2016, Mount Etna, Sicily On this 300 m PROBA-V image we can see the eruption of Mount Etna on 18 May 2016. Mount Etna is Europe’s tallest and one of the most active volcanoes in the world. It is the volcano’s first eruption this year.
24/04/2015, Calbuco volcano, Chile Above we show a 300 m image taken at April 24th, 2015, two days after the eruption of the Calbuco volcano (2,015 m altitude) in southern Chile. The eruption caused lava flows into a nearby lake, as well as an ash plume - clearly visible in the centre of the image - that rose to an altitude of ~10 kilometres.
26/10/2013, Mount Etna, Sicily This 300 m image shows an ash plume from the Mount Etna volcano (Sicily, Italy) on 26 October 2013. At this day, the volcano had its first major eruption since December 2002. Mount Etna (altitude 3329 m) is located at the edge of the Eurasian and African tectonic plates, being Europe’s tallest and one of the most active volcanoes in the world.
16/08/2014, Taranaki, New Zealand Mount Taranaki, or Mount Egmont, is an active but quiescent stratovolcano in the Taranaki region on the west coast of New Zealand's North Island. The 2518 m high mountain is one of the most symmetrical volcanic cones in the world. There is a secondary cone, Fanthams Peak (1,966 m) on the south side. This 100 m image of 16 August 2014 shows the almost perfect symmetry of the Taranaki volcano.
31/05/2014, Sangeang Api, Indonesia Due to elevated seismic activity, the Volcanological Survey of Indonesia issued an alert for Sangeang Api—an island volcano in the Flores Sea—on May 21, 2014. Sangeang erupted explosively on May 30, sending a thick column of ash and sulfur dioxide billowing into the atmosphere, as can be seen on this 300 m image of 31 May 2014.
29/12/2013, San Miguel, El Salvador San Miguel is one of El Salvador’s most active volcanoes. The December 2013 eruption sent a plume of ash about 9 kilometers into the atmosphere, see the brown plume in the middle of the 300 m image of 29 December 2013. The ash settled both on the slope of the volcano and on nearby towns, forcing 5,000 people to be evacuated.
