Title: Iceland land of fire

Iceland
land of fire ice

Modern Iceland
  • todays modern vikings are laying the fondation,
    iceland has evolved from fishing straight to
    national indepandance.
  • statisticly Iceland is the highest in hospital
    beds, doctors degrees ice land is already working
    on ways of making cars have less pollutionby
    using hydrogen it also supports future
    investments.
  • Iceland also supports investments in other
    cuontrys, making it second richest in scandanavia

Famous people
  • Halldore kiljan laxness using the people of
    Iceland as his subject halldore kiljan laxness
    became one of the most important Iceland authors,
    for works such as sjalfstoett (independent
    people) he was awarded the nobel prize for
    literature in 1995
  • Ingolfer anaarson ingolfer was the first person
    to settle in iceland in 1874. belived to be a
    norwegion chiefton, ingolfer, upon arriving in
    iceland established a farm located within the
    boundaries of reykjavik the present capitol.
  • Vigdis fimbagdo vigdis served 4 terms as
    president in 1980-96

did you know
  • Ice land is the land of fire and ice
  • Population is 298,737
  • Life expectancy 79(male) 83(female)
  • Infant mortality rate 3 per 1000

Iceland flag
the iceland flag was supposedly deprived from the
british flag
the red stands for fire
the white stands for ice
the blue stands for icelands mountains

The guysers
  • The geyser basin here takes on the name of the
    largest geyser here, Geyser. In fact that leads
    to some confusion on many web sites and on the
    part of some visitors. The Basin is Geyser but
    until recently Geyser itself was dormant and even
    now has relatively small eruptions. The large
    active geyser in the Basin is Strokkur. The name
    confusion does lead some to believe, as was the
    case of a geologist, that they have seen a 60 to
    90 foot  eruption of Geyser when instead they
    have seen the mighty Strokkur.

economy
  • Aluminum
  • Alcan's aluminum plant in Straumsvík, Iceland
  • Aluminum smelting is the most important
    power-intensive industry in Iceland. There are
    currently two plants in operation, with one under
    construction and two in the planning stage.
  • Alcan owns a plant in Straumsvík near the town of
    Hafnarfjörður which has been in operation since
    1969. Its initial capacity was 33,000 metric tons
    per year but has since been expanded several
    times and now has a capacity of 180,000 mtpy.
    Alcan is studying the feasibility of expanding
    the plant to a capacity of 460,000 mtpy
    negotiations are already underway with the power
    companies Landsvirkjun (the national power
    company) and Orkuveita Reykjavíkur, although it
    is yet unclear if the municipality of
    Hafnarfjörður will allow such an expansion, but
    the inhibitants of Hafnafjörður are going to vote
    whether they want to expand the aluminum smelting
    or not.

Icelands volcano
  • Laki (Icelandic Lakagígar) is a volcanic
    fissure situated in the south of Iceland
  • In AD 934, the Laki system produced a very large
    volcanic eruption, as a flood basalt in the
    Eldgjá eruption, which released 19.6 km³ (4.7
    mi³) of lava. In 1783-1784, the system erupted
    again, from the Laki fissure and the adjoining
    Grímsvötn volcano, spewing 15 km³ (3.6 mi³) of
    basalt lava and clouds of poisonous
    fluorine/sulfur-dioxide compounds that killed
    over 50 of livestock, leading to famine killing
    25-33 of the population.
  • On 8 June 1783, a fissure with 130 craters opened
    explosively at first because of the groundwater
    interacting with the rising basalt magma. Over
    time, the eruptions became less explosive, with
    the style changing from Plinian to Strombolian,
    and later to Hawaiian with high rates of lava
    effusion. This event is rated as VEI 4 on the
    Volcanic Explosivity Index, but the eight month
    emission of sulphuric aerosols resulted in one of
    the most important climatic and socially
    repercussive events of the last millennium

Icelands lakes
  • The Grímsvötn (Icelandic vatn, or "lake") are
    lakes in Iceland. They lie in the highlands of
    Iceland at the northwestern side of the
    Vatnajökull glacier and are covered by its ice
    cap. Beneath them is a large magma chamber of a
    powerful volcano. The location of the lakes is
    6425'N 1720'W, at an elevation of 1,725 m
    (5,659 ft).
  • Grímsvötn has a southwest-northeast-trending
    fissure system, and the massive, climatic
    impacting, Laki fissure eruption of 1783-1784 was
    a part of the same fissure system. In fact,
    Grímsvötn was erupting at the same time as Laki
    during 1783, but continued to erupt until 1785.
    Because most of the volcano lies underneath
    Vatnajökull, most eruptions have been subglacial
    in nature.
