6. Iceland is truly an island of
extremes and contrasts,
where large glaciers dwell in
the vicinity of some of the
most active volcanoes in the
world, creating an unusual
harmony of fire and ice.
The most famous and active
volcano in Iceland is mount
Hekla, which has erupted 18
times since 1104, the last
time in the year 2000.
7. There are over hundred volcanoes on Iceland’s central
plateau, most of which have not erupted in the past
thousand years.
However, between 30 and 40 are still active,
meaning that they have erupted within last
few centuries. 18 volcanoes have erupted
since the settlement of Iceland.
8. Surtsey is an volcanic island
and is called a stratovolcano.
It is made from many layers
of ash, lava, and other
particles. It is interesting that
it just popped out of the ocean
in 1963.
10. In two years the eruptions stopped but near its shores
a new island appeared – Sirtlingur.
11. Askja is a very complex volcano made up of three calderas. The volcano has mostly erupted
basaltic material over its recent history. The calderas are formed by passive sinking of the
land surface, much like we see in Hawai’i. However, at Askja, it appears that the calderas
are formed more violently due to explosive eruptions out of the ring fractures bounding the
calderas. The most recent activity at Askja was in 1961. That caldera-forming eruption in
1875 was large enough that ash and tephra fell as far away as Norway and Sweden.
14. Iceland is a geological "hot spot", causing the huge number of hot springs and
spouting geysers around the country. Iceland is packed with warm springs, pools,
fumaroles, mud pots, colourful soil and, of course, spouting geysers. The Geysir
area in Haukadalur valley is Iceland's most famous geothermal area, with the
world famous Geysir and Strokkur springs spouting regularly.
Historically, geothermal power has been limited to areas near tectonic plate
boundaries. Iceland, which lies on the mid-Atlantic Ridge, was basically formed
by the drifting apart of the American and Eurasian tectonic plates and therefore
creating the perfect settings for the usability of geothermal heat.
17. Solfatara –
a jet of sulfur dioxide
and hydrogen sulfide
with an admixture of
water vapors, carbon
dioxide, and other
gases. Solfataras are
emitted from lava and
other pyroclastic flows
and through vents and
fissures in the walls
and bottoms of craters
and on the slopes of
volcanoes. Their
temperature ranges
from 100° to 300°C.
20. A geyser is a hot spring that periodically erupts,
throwing water into the air. The word geyser comes
from the Icelandic verb geysa, "to gush".
21. Iceland uses geothermal
energy for a diverse area
of services, including
electricity production,
spas, home heating, fish
farming, and industrial
process heat. More than
95% of Iceland’s urban
population heat their
homes and buildings
with geothermal energy.
22. It’s possible to swim
in some rivers even in
the cold weather. The
water temperature is
about 37 C.
48. The lake is situated in the
crater of the volcano Askja in
the north-east of the glacier
Vatnajökull. Its name simply
means the lake of Askja. It
was created by an enormous
volcanic eruption in 1875.
On July 10, 1907, two German
scientists, Walter von Knebel
and Max Rudloff disappeared
while exploring the lake in a
small boat.
49. Vatnajokull is the biggest glacier in Europe. It covers about 8%
of the country and the average thickness is 400m.
61. Nootka Lupin and Lyme grasses are seemed to be the only species that prevent
the slope erosion.
62. Atlantic Puffin – is the
symbol of Iceland.
These birds have
bright- coloured beaks
and legs, very often
they are called “North
Parrots”. The Atlantic
Puffin likes to eat fish,
squid, and
crustaceans.
63. Iceland is one of the
main breeding
grounds for
waterfowl in Europe.
There are no fewer
than 16 species of
duck known to nest
in Iceland, including
two American
species; Barrow's
Goldeneye and the
Harlequin Duck.
64. The severe nature of the
island attracts by its beauty
and extravagance.
The tourists travel around
Iceland alone and in groups.

churches on the island
(XVIII century).
