Facts about Iceland

Iceland´s Geography
Iceland is an island of 103,000 km2 (39,756 square miles) – 24% larger than Austria or slightly smaller than Kentucky.  Iceland is the second largest island in Europe. The average height of Iceland is 500 meters above sea level and the highest peak is Hvannadalshnjukur, rising 2,111 m above sea level (most maps and books will quote the height 2,119 m but it was re-measured in 2004 to a mere 2,111 m). Over 11% is covered with glaciers, including Vatnajokull which is the largest glacier in Europe and outside the arctic regions. That is more land covered by glaciers than in all of continental Europe. Deserts and lava fields cover 63% of Iceland, lakes around 3% and 23% is vegetated land.

Iceland is located in the North – Atlantic Ocean, east of southern Greenland and northwest of the UK. The southernmost point of Iceland is Kotlutangi (63°23´N), the northernmost is Hraunhafnartangi (66°32´N), the easternmost is Gerpir (13°30´W) and the westernmost point of both Iceland and Europe is Bjargtangar (24°32´W).

Situated on the Mid-Atlantic Ridge, Iceland is a hot spot of volcanic and geothermal activity. In the past two centuries there have been about 30 volcanic eruptions and Hekla alone has erupted over 20 times since Iceland´s settlement. The geothermal heat supplies most of the nation with cheap, pollution-free heating and hot water.  Glacial rivers are harnessed to provide inexpensive hydroelectric power.

The Gulf Stream is what makes Iceland inhabitable, without it the whole country would most likely be covered with a shield of ice. The warm Gulf Stream tempers the winters so Iceland is not as cold as the name indicates.

Icelanders
Out of a population of approximately 320,000 around ¾ live in or around the capital of Reykjavik and its neighbouring towns in the south-west.  The rest live mostly around the coastline although part of the north-west is uninhabited. The central highlands are inhabited. About 20% of the 103,000 km2 are populated. This makes Iceland very attractive for nature enthusiasts; hikers, mountain bikers, nature photographers and bird watchers.

Literacy is among the highest in the world, about 99,9%, and average life expectancy is over 80 years. The National Church of Iceland, to which 88% of the people belong, is Evangelical Lutheran. Icelanders are a fairly homogeneous mixture of descendants of Norse and Celts; population of foreign origin is around 6%.

Iceland´s Economy
The standard of living is high, with income per capita among the best in the world. The economy is highly dependent upon fishing which accounts for 60% merchandise export earnings although less than 10% of the workforce is involved in fishing and fish processing. Like in many other western countries, two thirds of the working population is employed in the service sector, both public and private. Iceland is a member of the European Free Trade Association (EFTA) and the European Economic Area (EEA) but is not part of the European Union.

Icelandic History
Settlement started in the late 800s by Norse Vikings and in 930 the Icelandic settlers founded one of the world's first republican governments during the Old Commonwealth Age, described in the classic Icelandic Sagas. In 1262 Iceland lost its independence and did not become completely independent again until June 17, 1944 when the present Republic was founded. The country is governed by the Althingi (parliament).

Practical Info

The Lighter Side of Life
The most popular riddle to ask tourists: “What do you do if you get lost in an Icelandic forest?” – You stand up! (since there are not so many trees and the birch trees that do grow wild are not very tall).

The first question Icelanders are likely to ask you: “So, how do you like Iceland?”  (Even if you just got off the plane...  It has almost become a national joke).

Glaciers

Iceland is unparalleled as a place to study glaciers and glacial landforms. About 11% of the land area of Iceland is covered by glaciers, or about 11,400 square kilometres (4,400 square miles). By far the largest of the glacier ice caps is Vatnajökull (Vatnajokull) glacier in south-eastern Iceland. Covering an area of 8,300 km2, up to c. 900 m thick, Vatnajökull is equal in size to all the glaciers on the European mainland put together.

Other large glacier caps are Langjökull (Langjokull) (953 km2) and Hofsjökull (Hofsjokull) (925 km2) - both in the Central Highlands; Mýrdalsjökull (Myrdalsjokull) (596 km2), Eyjafjallajökull (Eyjafjallajokull) (78 km2) and the small Tindfjallajökull (Tindfjallajokull) (19 km2) in the South, and Drangajökull (Drangajokull) (160 km2) in the Northwest. On the tip of Snæfellsnes (Snaefellsnes) peninsula, across the bay from Reykjavík (Reykjavik), one of the smaller glaciers, Snæfellsjökull (Snæfellsjokull) (11 km2), can be seen in clear weather - a fascinating sight at sundown. The main reason that most of the glaciers are located in the Southern Highlands of Iceland is the much greater precipitation in the South than in the North. At the time when the country was being settled, the glaciers were small, but they grew fast when it started getting colder during the latter part of the Middle Ages and up to the turn of the 19th century. Travelling across the glaciers was rare in earlier times, but nowadays it’s quite common when the weather is good. However, inexperienced hikers should not undertake glacier trips unless accompanied by professionals. You can join a glacier tour in a super-jeep, or go snowmobiling.

Types of glaciers in Iceland
Glaciers are classified based on their size and their relationship to topography. Almost all types of glaciers are found in Iceland, ranging from the small cirque glaciers (named for the bowl-like hollows they occupy, called cirques) to extensive dome-shaped glacier ice caps reminding one of the inland ice of Greenland. Most glaciers in Iceland classify as ice caps. Ice caps are miniature ice sheets, covering less than 50,000 km2, which form primarily in polar and sub-polar regions that are relatively flat and high in elevation. Ice caps may cover an entire mountain range or a volcano. Iceland´s Vatnajökull glacier (8,300 km2) is the largest ice cap in Europe; the area it covers is bigger than the state of Rhode Island, USA, and, hidden beneath its ice cap are no less than seven volcanoes, most of them active. The ice caps are drained by broad lobe-shaped outlets or by valley glaciers of the alpine type. Glacier tongues that drain an ice cap or ice sheet and outlet glaciers are also found in Iceland. Breiðamerkurjökull (Breidamerkurjokull), Skeiðarárjökull (Skeidararjokull), Skaftafellsjökull (Skaftafellsjokull), and Svínafellsjökull (Svinafellsjokull) are some of the larger outlet glaciers that drain the ice cap Vatnajökull.

Formation of Glaciers
During the last Ice Age almost all of the country was covered by permanent snow and glacier ice. Glaciers form simply because more snow falls in the winter than can melt in the following summer. A glacier is a thick mass of ice that forms from the compaction and recrystallization of snow. When temperatures remain below freezing following a snowfall, a fluffy accumulation of new snow soon begins to change. Evaporation and recondensation of water causes recrystallization to form smaller, thicker and more spherical grains of ice. This recrystallized snow is called firn. As more snow is deposited and becomes firn, the pressure on underlying grains increases. When the thickness of the snow and ice exceeds tens of metres, the weight is sufficient to cause the firn to grow into even larger ice crystals. In glaciers where melting occurs in the zone of snow accumulation, snow may be transformed into ice very quickly by melting and refreezing (over several years).

Glacier features
The size and extent of glaciers are determined by the climate of a region. The balance between what accumulates high up on the upper part of the glacier, and what melts near the glacier's foot (terminus) is called the glacier mass balance. Accumulation occurs high up on the glacier (accumulation zone) where snow doesn't melt even during summer. The ice in a glacier is moving under the force of gravity and, as this material moves down the glacier, it eventually reaches the end of the glacier and melts in the ablation zone. The line that separates these two zones is called the equilibrium line. The elevation of this line varies each year depending on the temperatures that year and the amount of snowfall. If a glacier has more accumulation than ablation for several years, the glacier may advance. If more ablation occurs than accumulation, the glacier will retreat. At all times ice is continually moving down the glacier, even when the terminus is stable for several years. No matter what the size of the glacier, these basic principles determine glacier behaviour. The Icelandic ice caps, with their numerous outlet glaciers, are wet-based and temperate. This means that they are at the pressure melting point throughout the ice mass and during the whole year (except for the surface layers in winter).

The yearly average temperature in Iceland is around 5°C, so there would not have to be a great temperature drop for the glaciers to start growing and advancing again. The Icelandic glaciers are the so-called thaw-glaciers with temperatures around 0°C. Another characteristic of Icelandic glaciers is the great number of constantly moving glacier tongues. Sometimes they advance fast and then retreat gradually again, until the balance between the advance and the melting has been reached. The glaciers are an important source of water for the electrical production in the country. For that reason, they are being constantly monitored and comprehensively researched.

Volcanoes

Iceland contains some fascinating volcanoes. The volcanism in Iceland is attributed to the combination of Mid-Atlantic Ridge activity and hot spot activity. Eruptions occur about every 5-10 years. The Mid-Atlantic Ridge is visible on land in Iceland and gives an indication of volcanic activity not normally observed.

Almost 60% of the world's regional fissure eruptions have been in Iceland.

Iceland is one of the most active volcanic regions on Earth. It is estimated that 1/3 of the lava erupted since 1500 A.D. was produced in Iceland. Iceland has 35 volcanoes that have erupted in the last 10,000 years. Eleven volcanoes have erupted between 1900 and 1998: Krafla, Askja, Grímsvötn (Grimsvotn), Laki-Fögrufjöll (Laki-Fogrufjoll), Bárðarbunga (Bardarbunga), Kverkfjöll (Kverkfjoll), Esjufjöll (Esjufjoll), Hekla, Katla, Surtsey, and Heimaey. Most of the eruptions were from fissures or shield volcanoes and involve the effusion of basaltic lava.

The 1783 eruption at Laki was the largest single historic eruption of basaltic lava (12-15 cubic km). Recent eruptions include the 1974 -1984 eruption at Krafla, a brief eruption at Hekla in 1991 and again on 26 February 2000, four eruptions at Grimsvotn: in 1996, 1998, 2004, 2011 and the eruption at Eyjafjallajökull (Eyjafjallajokull) in 2010.
