Jan Mayen as an island has, thus, hardly experienced more than the last three Quaternary ice ages.<\/p>\n<p>The island rises from a subsea volcanic mountain chain called the Jan Mayen Ridge, which forms the boundary of the 1500-metre-deep Iceland Plateau in the north-east. North of Jan Mayen, the sea floor slopes fairly steeply down to a depth of more than 2000 metres in the Jan Mayen Rift Zone.<\/p>\n<p>This rift zone is an active transform fault zone, in which the mid-ocean ridge between Europe and America is offset by approximately 200 km. This displacement is still taking place at an average rate of a couple of centimetres a year.<\/p>\n<p>A small segment of the spreading zone probably underlies the north-eastern tip of Jan Mayen. The volcanism and earthquake activity on and around the island are due to this location.<\/p>\n<section class=\"paragraph clearfix\">\n<h3 class=\"heading--section-title\">Volcanic landscape<\/h3>\n<div id=\"attachment_14819\" style=\"width: 310px\" class=\"wp-caption alignright\"><a href=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-14819\" class=\"wp-image-14819 size-medium\" src=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology-300x217.jpg\" alt=\"kart\" width=\"300\" height=\"217\" srcset=\"https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology-300x217.jpg 300w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology-450x326.jpg 450w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology-768x556.jpg 768w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology-1030x746.jpg 1030w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology-705x510.jpg 705w, https:\/\/npolar.no\/wp-content\/uploads\/2018\/09\/map-jan-mayen-quaternary-geology.jpg 1381w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><p id=\"caption-attachment-14819\" class=\"wp-caption-text\">Quaternary geological map of Jan Mayen. Map: Kirsti H\u00f8gvard \/ Norwegian Polar Institute (1996)<\/p><\/div>\n<p>The landscape on Jan Mayen is influenced by the volcanic origin of the island. The northernmost active volcano in the world which rises above sea level is located on the northern part of the island. Beerenberg is a majestic volcano, towering to a height of 2277 metres, and having regular sides which slope at about 30\u00b0 around the Central Crater and continue downwards to the main massif at around 15\u00b0. This break of slope is a result of a young <em>stratovolcano<\/em>, built of an alternation of lava and tephra, having formed on an older <em>shield volcano<\/em>, mainly composed of lava. Numerous parasite craters built of tuff, slag and tephra pockmark the lower slopes.<\/p>\n<p>Beerenberg has more than twenty glaciers, which cover some 30 % of the area of the island. Some of their snouts reach right down to sea level.<\/p>\n<p>The bedrock on the island consists of basalt lava flows alternating with pyroclastic rocks. The latter are rocks of volcanic origin flung out during eruptions and more or less consolidated in the air. The youngest volcanic eruptions in 1970 and 1985 took place on the lower slopes on the north-east side of Beerenberg. The Central Crater and Egg Island, a crater remnant on the south side of the mountain, have permanent fumarole activity (emission of hot steam). There is thought to be an average of one volcanic eruption on Jan Mayen every 100-130 years.<\/p>\n<section class=\"av_textblock_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role='complementary' class='avia_textblock NP-factsheet-enfold alwaysToggle '   itemprop=\"text\" ><p class='title'> The volcanic eruption in 1970 <\/p><div class='hsep'><\/div><div class='NP-factsheet-content'>\n<p>The largest known volcanic eruption occurred in September-October 1970, when a plume of smoke up to 11&nbsp;km high was observed from a passing passenger plane.<\/p>\n<p>The eruption took place from several craters along a 5&nbsp;km-long zone of fissures close to the north-east tip of Jan Mayen. Lava production lasted more than 4 weeks, and about 0.5&nbsp;km<sup>3<\/sup>&nbsp;of lava was produced. Over 4&nbsp;km<sup>2<\/sup>&nbsp;of new land was formed, spread out on the former seabed for up to 300&nbsp;metres.

The Dutch established land stations for whaling, which were gradually abandoned after 1634. Research activities date back to 1882-83 and their remains are still to be found in Maria Muschbukta, protected according to preservation regulations. At the beginning of the 1900s, Norwegians started to hunt for Arctic fox on the island. Of the original 13 hunting cabins, five still remain. In 1921 Hagbart Ekerold established the first meteorological station on Jan Mayen, and the following year, the Norwegian Meteorological Institute annexed a part of the island. In 1926 the Institute annexed the whole island, but it was not until 27 February 1930 that Jan Mayen was incorporated in the Kingdom of Norway by law.<\/p>\n<\/div><\/div><\/div><\/section>\n<\/div><\/p><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-l29zmm-ec193c19358e98eb87d74cf10e629482\">\n.flex_column.av-l29zmm-ec193c19358e98eb87d74cf10e629482{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-l29zmm-ec193c19358e98eb87d74cf10e629482 av_two_fifth  avia-builder-el-3  el_after_av_three_fifth  el_before_av_masonry_gallery  avia-builder-el-last  flex_column_div av-zero-column-padding  '     ><p><section  class='av_textblock_section av-jmrj4q5c-6202440d10641b7734005ef11f3d00e5 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><div id=\"attachment_24052\" style=\"width: 410px\" class=\"wp-caption alignright\"><a href=\"https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-24052\" class=\"wp-image-24052\" src=\"https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-1030x1030.png\" alt=\"kart over jan mayen\" width=\"400\" height=\"400\" srcset=\"https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-1030x1030.png 1030w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-450x450.png 450w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-100x100.png 100w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-80x80.png 80w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-300x300.png 300w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-768x768.png 768w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-36x36.png 36w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-180x180.png 180w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen-705x705.png 705w, https:\/\/npolar.no\/wp-content\/uploads\/2019\/05\/janmayen.png 1087w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a><p id=\"caption-attachment-24052\" class=\"wp-caption-text\">Map: Norwegian Polar Institute<\/p><\/div>\n<\/div><\/section><br \/>\n<section class=\"av_textblock_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role='complementary' class='avia_textblock NP-factsheet-enfold no '  style=' '  itemprop=\"text\" ><p class='title'>Related pages<\/p><div class='hsep-relevantlinks' ><\/div><div class='NP-factsheet-content'><div id=\"toggleable-0\" class=\"toggleable content expanded\" aria-hidden=\"false\">\n<ul>\n<li><a href=\"http:\/\/topojanmayen.npolar.no\/?lang=no\" target=\"_blank\" rel=\"noopener\">Interactive map of Jan Mayen<\/a><\/li>\n<li><a href=\"https:\/\/mosj.no\/en\/\">Environmental Monitoring of Svalbard and Jan Mayen (MOSJ)<\/a><\/li>\n<li><a href=\"https:\/\/placenames.npolar.no\/\">Search place names on Jan Mayen<\/a><\/li>\n<\/ul>\n<\/div>\n<\/div><\/div><div tabindex='0' role='button' class=' NP-factToggle' style='text-align:center;'><i class='fas fa-angle-down fa-2x'><\/i><\/div><\/section><br \/>\n<section class=\"av_textblock_section\"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role='complementary' class='avia_textblock NP-factsheet-enfold no '  style=' '  itemprop=\"text\" ><p class='title'>External links<\/p><div class='hsep-relevantlinks' ><\/div><div class='NP-factsheet-content'><ul>\n<li><a href=\"https:\/\/www.statsforvalteren.no\/nb\/Nordland\/Miljo-og-klima\/Verneomrader\/Forvaltningsplan-for-Jan-Mayen-naturreservat\/\">Management plan Jan Mayen Nature Reserve<\/a><\/li>\n<li><a href=\"http:\/\/hdl.handle.net\/11250\/2437047\" target=\"_self\" rel=\"noopener\">Susan Barr (2016).&nbsp;Jan Mayens kulturminner 1980-2016.
