The area of the volcano contributes to the most serious natural hazard area of Iceland. [41] The most likely large eruption had in 2019 a 89% probability of occurring within 30 years and would likely be associated with tephra production of about 1.5 km 3 (0.36 cu mi) which can be compared with the 0.25 km 3 (0.060 cu mi) that disrupted air ...
Photos show Icelandic volcano erupting for 10th time in 3 years Lava spurts and flows after the eruption of a volcano in the Reykjanes Peninsula near Grindavik, Iceland, in this handout picture ...
[9] [10] The most recent shield volcanoes to form in this particular area of the Reykjanes region were Sandfellshæð [ˈsantˌfɛlsˌhaiːθ] and Þráinsskjöldur [ˈθrauːɪnsˌscœltʏr], which emerged around 14,000 years ago. [11] This volcanic activity was triggered by the retreat of glaciers at the conclusion of the last glacial period.
Hekla (Icelandic pronunciation: ⓘ), or Hecla, [2] [3] is an active stratovolcano in the south of Iceland with a height of 1,491 m (4,892 ft). Hekla is one of Iceland's most active volcanoes; over 20 eruptions have occurred in and around the volcano since the year 1210. [4]
There are about 32 volcanic systems in Iceland. Volcanic system means a volcano-tectonic fissure system and – very often a bigger volcano, a so-called central volcano which in most cases is a stratovolcano and may contain a caldera. [2] [3]
There are too many presumed extinct or now inactive volcanic features to list all of these below, so most monogenetic volcanoes can not be mentioned individually. This list of volcanoes in Iceland only includes major active and dormant volcanic mountains, of which at least 18 vents have erupted since human settlement of Iceland began around 900 AD.

The Hekla 3 eruption (H-3) c. 1000 BC is considered the most severe eruption of Hekla during the Holocene. [2] It threw about 7.3 km 3 of volcanic rock into the atmosphere, placing its Volcanic Explosivity Index (VEI) at 5. This would have caused a volcanic winter, cooling temperatures in the Northern Hemisphere for several years afterwards.
