Iceland experiences frequent volcanic activity, due to its location both on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and being over a hotspot.Nearly thirty volcanoes are known to have erupted in the Holocene epoch; these include Eldgjá, source of the largest lava eruption in human history.
[10] [11] It is dated to about 200 CE, [2] [a] and was also associated with the eruption of viscous lava that covered 30 km 2 (12 sq mi). [1] In all three large, perhaps up to VEI 4 plinian rhyolitic [b] eruptions have occurred during the Holocene producing tephra. [1] [c] These occurred about 1800, 4000 and 8500 years ago. [1] [a]
The Hofsjökull volcanic system is found on the north-eastern edge of the Hreppar microplate, so has the North American Plate to its north and the Eurasian Plate to its east. [ 19 ] [ 9 ] It is classified as being in the Mid-Iceland belt that connects the Western volcanic zone to the intersection of the Northern volcanic zone and the Eastern ...
It covers an area of 830 km 2 (320 sq mi), [2] with the icecap top being 1,782 metres (5,846 ft), [1] and bottom being at about 600 m (2,000 ft). [5] There are other summits relating to the underlying volcano with two being at 1,765 m (5,791 ft). [6] [1] Hofsjökull is the source of several rivers including the Þjórsá, Iceland's longest ...
Another Icelandic volcano erupted in 2011, and in that case only 1 per cent of flights in northern Europe were cancelled – rather than 100 per cent in 2010. Eruption could last ‘for weeks ...
Iceland, which is roughly the size of the U.S. state of Kentucky, boasts more than 30 active volcanoes, making the north European island a prime destination for volcano tourism - a niche segment ...
In addition to the main mountain, the Snæfell volcanic system has a series of fissures and smaller subglacial eruptive features, oriented in a south-west to north-east direction (27°), almost parallel to the active northern volcanic zone, [8] which is 45 km (28 mi) to its west. [6]
