Eyafjallajökull volcano (its name meaning Island-Mountain under a glacier) under the small homonymous glacier in southern Iceland erupted spectacularly on 20 March 2010, after having been dormant for almost 200 years. During its most violent phase, the subglacial eruption produced large ash plumes that drifted over Europe and forced an unprecedented closure of airspace over most of Europe for several days in mid April 2010. -> See whole entry
Falso Azufre volcano is a volcanic complex on the Chile/ Argentina border. The 15 km long complex contains overlapping craters and lava domes. The western part contains the highest peak, Cerro Falso Azufre.
Fantale (also spelled Fantalle or Fantala) is a large stratovolcano in the Ethiopian Rift Valley west of Lake Awash. It contains a large spectacular summit caldera.
Fantale's historic eruptions produced lava flows that descended to the east side into the valley and lake Awash. An eruption during the 13th century destroyed a town and church located south of the volcano. In 1820, a 4 km long fissure eruption occured on the east flank and sent basaltic lava flows both into the caldera and outside, reaching the bottom of the Rift valley. -> See whole entry
Fort Selkirk is a volcanic field near the junction of the Yukon and Pelly rivers in central Yukon. It is the northernmost young volcanic field in Canada.
The volcano consists of large valley-filling lava flows and 3 cinder cones.
The volcanic field developed at the intersection of two prominent fault lines, one running east-west, marked by the Pelly River and the lower Yukon River, and the other one NW-SE, defined by the upper Yukon River.
The first activity of the volcanic field were effusive, valley-filling eruptions of fluid basalt lava, followed by the construction of 3 cinder cones during strombolian-type eruptions and related emplacement of viscous aa lava flows. -> See whole entry
