Iceland Volcano : Brennisteinsfjöll volcano

Iceland Volcano : Brennisteinsfjöll volcano

Brennisteinsfjöll volcano Data:

• crater rows 626 m (2,054 ft)
• Iceland, 63.92°N / -21.83°W
• Current status: dormant (1 of 5)
• Typical eruption style: effusive (lava flows).
• Eruptions from Brennisteinsfjöll: 1000(?), 1188(?), 1200(?), 1341. The Brennisteinsfjöll volcanic system, located east of Kleifarvatn lake, consists of a series of NE-SW-trending crater rows and small shield volcanoes.

Brennisteinsfjöll volcano Background:
Postglacial and historical basaltic lavas cover a wide area. An eruption in 1000 AD was dated by its occurrence at the time of a meeting of the Icelandic outdoor parliament at Thingvellier. The most recent eruption at Brennisteinsfjöll took place in the 14th century.

Iceland Volcano: Krísuvík volcano

Iceland Volcano: Krísuvík volcano

Krísuvík volcano Data:

• crater rows 379 m (1,243 ft)
• Iceland, 63.93°N / -22.1°W
• Current status: dormant (1 of 5)
• Typical eruption style: effusive (lava flows).
• Eruptions from Krísuvík: 1075, 1100, 1151, 1188, 1340(?) Krísuvík is a system of eruptive fissures, craters and small basalt shields in SW Iceland west of lake Kleifarvatn. A large eruption occurred from the Ogmundargigar fissure in 1188.

Krísuvík volcano Background:
The Krísuvík volcanic system is a group of NE-SW-trending basaltic crater rows and small shield volcanoes cutting the central Reykjanes Peninsula west of Kleifarvatn lake.
Several eruptions have taken place since the settlement of Iceland, including the eruption of a large lava flow from the Ogmundargigar crater row around the 12th century, probably in 1188. The latest eruption at Krísuvík took place during the 14th century.
Uplift in 2009: Between May and November 2009 the area over Krisuvik Volcano was uplifted by 3 cm.

Iceland Volcano: Ljósufjöll volcano

Iceland Volcano: Ljósufjöll volcano

Ljósufjöll volcano Data :
Fissure vents 988 m (3,241 ft)
Western Iceland, 64.87°N / 22.23°W
Current status: dormant (1 of 5)
Typical eruption style: effusive fissure eruptions (lava flows).
Eruptions from Ljósufjöll volcano: 960 AD +-10 years


Ljósufjöll volcano Background:
The Ljósufjöll volcanic system at the eastern end of the Snaefellsnes Peninsula is a group of basaltic cinder cones and lava flows along short fissures on a roughly 90-km-long WNW-ESE line.

The volcanic field is about 20-km wide at the eastern end and narrows to about 10-km width on the west. Young-looking cinder cones and lava flows with morphologically fresh surfaces testify to numerous eruptions during the past 10,000 years. The latest eruption post-dated the settlement of Iceland, and took place about 1000 years ago.

Iceland Volcano: Lysuhóll volcano

Iceland Volcano: Lysuhóll volcano

Volcano Data :

• Pyroclastic cones 540 m (1,772 ft)
• Iceland, 64.87°N / -23.25°W
• Current status: dormant (1 of 5)
• Typical eruption style: Strombolian eruptions, lava fountains and lava flows.
• Eruptions from Lysuhóll: None during historic times
• Lysuhóll is Iceland's smallest volcanic system.

Lysuhóll Volcano Background:
It consists of a chain of small alkali olivine basaltic cinder cones and vents along a WNW-ESE line cutting across the central Snaefellsnes Peninsula in western Iceland.

The slightly arcuate line of Quaternary vents extends to the northern coast of the peninsula. Lysuhóll is the central of three volcanic systems occupying the peninsula. The latest eruption from Lysuhóll is undated, but the volcanic field has been active during the Holocene.

Iceland Volcano: Snaefellsjökull volcano

Iceland Volcano: Snaefellsjökull volcano

A large ice-covered volcano at the western tip of the Snaefellsnes Peninsula in western Iceland. Its last eruption dates about 1750 years back.

Background of Snaefellsjökull volcano:
Numerous pyroclastic cones dot the flanks of the 1448-m-high stratovolcano, the only large central volcano in this part of Iceland. Lower-flank craters produced basaltic lava flows and upper-flank craters intermediate-to-silicic material. Holocene lava flows extend to the sea over the entire western half of the Snaefellsjökull volcano. Several Holocene silicic eruptions have originated from the summit crater. The latest dated eruption of Snaefellsjökull volcano took place about 1750 years ago; several lava flows may be even younger.

Iceland and its Volcanoes

Iceland and its Volcanoes
Iceland has the land area of Virginia and the population of Virginia Beach (about 260,000 people). The country has the highest literacy rate (100%) of any nation in the world. Its history has always been closely related to volcanoes and knowledge of many volcanic eruptions since the middle ages are preserved in accounts.
Iceland established its own parliament in 930 and recorded its first historical volcanic eruption only a few years later. After a golden age of literature in the 12th and 13th centuries (when the sagas were written), natural history reporting reached a low around the 15th century. In the years 1707-09 a third of the population died from smallpox, and the 1783-84 Laki eruption killed a fifth of the remaining population by famine. Iceland gained sovereignty from Denmark in 1918 and complete independence in 1944.
Iceland is noted for subglacial and regional fissure eruptions related to the rifting process between the separating plates.

ICELAND

ICELAND
Iceland, the land of ice and fire, is a true paradise for volcanologists. In few places on earth, geology and human history are so closely connected to volcanism as on Iceland. The island owns its existence to a large volcanic hot spot sitting on a mid-oceanic ridge, a unique setting. The plate boundary between the American and Eurasian tectonic plates crosses Iceland from south to North and the spreading process can be directly measured and observed on land.
