Eldfell Volcano - Westmann Islands is a 0.8 mile loop trail located near Vestmannaeyjar, Southern, Iceland that offers scenic views and is good for all skill levels. By early February, the heavy tephra fall had abated, but lava flows began to cause serious damage. In Europe, the eruption was one of the biggest news items while it continued, competing for front page space with breakthroughs then being made in the Vietnam War peace talks in Paris. Apart fr… Although plagued by poor water supplies and piracy during much of its history, Heimaey became the most important centre of the Icelandic fishing industry, having one of the few good harbours on the southern side of the country, and being situated in very rich fishing grounds. Volcanic ash fell over most of the island, destroying many houses, and a lava flow threatened to close off the harbour, the island's main income source via its fishing fleet. In total, the volume of lava and tephra emitted during the five-month eruption was estimated to be about 0.25 km³ (0.06 cubic miles). At about 01:55 on 23 January, a fissure opened up on the eastern side of the island, barely a kilometre away from the centre of the town of Heimaey. The islanders have planted grass around the lower slopes of the otherwise bare hill, to stabilise it against further erosion, and eventually it is expected that most of the volcano will be covered by grass, as neighbouring Helgafell is. It is estimated that a third of all the basaltic lava erupted in the world in recorded history has been produced by Icelandic eruptions. Eldfell: Eldfell is a very small volcano, only around 650 feet high, on the Icelandic island of Heimaey. Small tremors are very common at plate boundaries, and nothing here indicated that they heralded a major eruption. By mid-1974, about half the pre-eruption population had returned to the island, and by March 1975, about 80% had returned. Kristjansson L., Simon I., Cohen M.L., Björnsson S. (1975). There were not many severe environmental impacts from the eruption. The fissure extended across the entire island, producing a spectacular curtain of fire. There was some underwater volcanic activity during the ongoing eruptions, which caused the water pipeline to Heimaey to break. The threat of lava flows cutting off the harbour was the most significant facing the town. The line of the 1973 fissure south of Eldfell is clearly seen, 4 Destruction of houses, creation of land, A description of the eruption and evacuation, Eyewitness account of the early days of the eruption, Eruptive history of the Vestmannaeyjar archipelago, https://www.academickids.com:443/encyclopedia/index.php/Eldfell, Centre for Short-Lived Phenomena bulletins 1545, 1547, 1552, 1567, published by the. However, Professor Þorbjörn Sigurgeirsson of the University of Iceland calculated that it should easily be possible to cool the lava flows to the point of solidification by spraying them with sufficient sea water. Its name means Fire Mountain, and it formed in a volcanic eruption which began without warning just outside the town of Heimaey on 23 January 1973. From 23:00 until 01:34 on 23 January, seven tremors were detected, the largest of which measured 2.7 on the Richter scale. This page was last modified 00:27, 6 May 2005. There was great concern that the lava flow would impede access to the harbor, which was vital to this fishing community. By the end of the eruption, Eldfell stood about 220 m (720 ft) above sea level. The lava which came from the volcanoes on the plate borders formed the island. The Heimaey Eruption: Iceland 1973 documented the battle to save the town from the volcano, Eldfell. Since then, its height has dropped by 18-20 m (60-65 ft), due to slumping and compacting of the unconsolidated gravelly tephra as well as wind erosion. Most of the population left the island by boat. Not too much, so you don't need to be top fit to get there. Eruptions are a big part of Westman Islands history and on the islands there are 2 Volcanoes. Although you probably want to do this hike earlier in the day. In 1973, the Eldfell volcano erupted. The insides of lava flows can remain at temperatures of several hundred °C for many years due to the very low thermal conductivity of rock. Volcano, vent in the crust of Earth or another planet or satellite, from which issue eruptions of molten rock, hot rock fragments, and hot gases.A volcanic eruption is an awesome display of Earth’s power. Later on in the eruption, a surge of lava destroyed one fish processing plant and damaged two others, and also demolished the town's power generating plant. The last land addition to Iceland was formed in 1963: This island is called Surtsey and is located 30km/18.6 miles off the main island. One contingency plan devised should the harbour be closed off was to cut through a low sand spit on the north side of the island to provide a new channel into the harbour, but it was hoped that if the lava flow could be slowed, this would not be necessary. Failure of pump shafts became a problem after a few weeks, probably because they were designed for pumping oil rather than water, and new and improved shafts had to be manufactured in Reykjavík and brought in. Sixteen years after it roared to life, the 725-foot Eldfell volcano looks down almost benignly these days on the town it came close to destroying. After these pumps began to cool the flow advancing towards the town, its movement slowed dramatically and soon stopped. During the early days of the eruption, the rate of lava and tephra emission from the fissure was estimated to be 100 m³/s, and within two days, the lava fountains had built a cinder cone over 100 m high. The scheme was extended to several more houses and the hospital, and in 1979 construction began of four larger plants to extract heat from the flows. Efforts to prevent the loss of the harbour are described further below. The ground on Heimaey started to quake and fissures formed. However, offshore eruptions may have taken place in 1637 and 1896. They were too weak to be felt by the residents of the island, but a seismic station 60 km away recorded over 100 small tremors between 01:00 and 03:00 on 22 January. The volume of lava being emitted during the eruption fell steadily after the first few days. The trail is … The island of Heimay’s fishing port was at risk of being demolished from the eruption. Once the viability of lava cooling had been proven, efforts to halt the flows were increased. The fissure rapidly extended to a length of 2 km (1.25 miles), crossing the island from one shore to the other. The attention focussed on the island as a result of the eruption led to a later upsurge in tourism once the eruption was over [1] (http://www.xtreme.is/net/skraarsafn/vestmannaeyjar_is//1097082947.pdf). The flows were thick and blocky aa flows, and covered the ground to average depths of about 40 m (130 ft), reaching 100 m (330 ft) thick in places. Nearly all of the island’s 5,300 residents were evacuated by fishing boats to the mainland, and they temporarily could not return. The pumping capacity was increased in early March, when a large chunk of the crater wall broke away from the summit of Eldfell and began to be carried along the top of the lava flow towards the harbour. In the early hours of the eruption, the Icelandic State Civil Defence Organisation evacuated the entire population of Heimaey, having previously developed evacuation plans for an emergency such as this. Today the ground is still hot enough in places to bake bread or char wood. Submarine activity also occurred just offshore at the northern and southern ends of the fissure. Consider things such as access and accommodation at the base of Eldfell, as well as the logistics of climbing to the summit. By the end of January, tephra covered most of the island, reaching 5 m (16 ft) deep in places.

Facts About Eyjafjallajökull Volcano Background Prior to 2010, Eyjafjallajökull had erupted in 920, 1612-1613, and 1821-23. The workers dubbed themselves 'The Suicide Squad', and managed to lay pipes up to 130 metres (430 ft) inward from the flow front, directly over the advance. Create your own unique website with customizable templates. The most prominent feature on Heimaey before 1973 was Helgafell, a 200 m (650 ft) high volcanic cone formed in an eruption about 5,000 years ago. Apart from falling ash, some houses were also burned down by fires caused by lava bombs, or overridden by advancing lava flows. First an eruption fissure, about 1,500 m long, opened seawards only about 200 – 300 meters from the easternmost part of the town. Eldfell Volcano, Heimaey, Westmann Isles, Iceland, 1973 Bárðarbunga was one of the most recent eruptions to occur in the country - it erupted over a … Flakkarinn rafted several hundred metres towards the harbour along the top of the lava flow, but came to a halt well away from the water's edge. We did the hike before we visited the museum and it might've been helpful to do it the other way around. The eruption caused a major crisis for the island and nearly led to its permanent evacuation. While the island had been evacuated up to six hours after the first eruption, there was still no clean drinking water supply for the very few people who chose to stay on the island. Eldfell Climbing Notes. It is a wonder how the island risked permanent evacuation from the eruption, yet was prevented manually form destroying major ports, which Iceland greatly rely on for their economy. Volcanic ash fell over most of the island, destroying many houses, and a lava flow threatened to close off the harbour, the island's main income source via its fishing fleet. The Vestmannaeyjar archipelago was settled in about 874 AD, originally by escaped Irish slaves belonging to Norse settlers on the mainland. The efforts of the islanders to halt the lava flows received particular attention, with coverage in publications such as National Geographic (e.g. Eldfell ("fire mountain" in Icelandic) is a volcano on the island of Heimaey in the Vestmannaeyjar archipelago 15 miles (25 km) south of Iceland. These settlers gave the islands their name, Ireland being west of mainland Scandinavia. The trail is primarily used for hiking and nature trips and is best used from June until September. The water cooling of the lava was slow, but achieved a maximum efficiency, with almost all the water being converted to steam. An operation was mounted to cool the advancing lava flow by pumping sea water on it, and this was successful in preventing the loss of the harbour. Yet, while eruptions are spectacular to watch, they can cause disastrous loss of life and property, especially in densely populated regions of the world. Head to Eldfell Volcano, located nearby. Visit the Westman Islands … Poisonous gases, mostly carbon dioxide, became concentrated in many buildings partially buried by tephra, and several other people were affected when entering these buildings. Helgafell, the supposedly dormant volcano, seen from the slopes of Eldfell, the volcano created by Helgafell’s eruption. The resourceful local people pumped seawater onto the lava which diverted the … Please submit any useful information about climbing Eldfell that may be useful to other climbers. A few days after the eruption began, the prevailing wind direction moved to the west, resulting in extensive tephra falls over the rest of the island, causing extensive property damage. Submarine activity just north of the fissure severed an electric power cable and a water pipeline which supplied electrical power and water from the Icelandic mainland, and lava began to flow into the harbour, as situation which caused serious concerns - if the harbour was destroyed, the island's fishing industry would be devastated. We walked to the trailhead from the harbor without much difficulty. Scientists have speculated that volcanic activity in the archipelago may be increasing due to the southward propagation of the rift zone which crosses Iceland. The ash and lava left homes and other buildings frozen in time just as people left them. This would mean a significant decrease in Iceland’s importing income. Lava flows also moved into the sea east of the island, creating new land that would eventually add over 2 km² (0.8 square miles) to the island, and into the eastern parts of town, destroying several hundred houses. The small town of Heimaey (hey-my) is encased in a fortress of jagged lava; its port sits at the end of a contorted waterway that carves a path between towering cliffs dotted with bird nests.Although only a few kilometres from the mainland, Heimaey feels light years away, … The area of the lava flow is 2.1 km 2, and the average thickness is about 70 m. The population was alerted to the situation by fire engines sounding their sirens, and gathered by the harbour with just the small amount of possessions they were able to carry. See nearby properties Eldfell & Helgafell If seeing the sights is on your list of things to do, head to Eldfell & Helgafell— just one of the landmarks located 1.2 mi (1.9 km) from central Ofanleiti. On the night in question, Eldfell, a new volcanic cone, was formed. Experimental heating systems were soon devised, and by 1974 the first house was connected. Nonetheless, be prepared with hiking shoes, right clothing in function of the weather (and even in summer I'd suggest to have a cap, windbreaker clothes, gloves) and water. View of Heimaey before the eruption: Town of Vestmannaeyjar with Helgafell in the right back-ground (photo courtesy of Sólarfilma). About 2.5 km² (0.96 square miles) of new land was added to the island, increasing its pre-eruption area by some 20%. The Hotel Vestmannaeyjar and Aska Hostel are located within 2 miles (3 kilometers) of Eldfell Volcano. The abundant tephra produced by the eruption was used to extend the runways at the island's small airport, and also as landfill on which 200 new homes were built. Volcano overwhelms an Icelandic village, 1973). As Heimaey was responsible for some 25% of Iceland's total annual catch, the effect on the whole country's economy would be significant. This unique and famous sight in Iceland was formed by volcanoes, looking like a giant elephant rising out from the sea. At 1.55am on the 23 january a fissure 1800m long opened up from one shore to the other. Shortly before the end of the eruption, a tiltmeter 1.15 km from the crater which had been measuring ground deformation throughout the eruption detected subsidence towards the crater, implying that the shallow magma chamber which had fed the eruption was emptying out. The fissures grew to 1,600 metres (5,200 ft) in length, and lava began to erupt. Efforts to mitigate the hazards presented by the accumulation of poisonous gas included the building of a large tephra wall to divert gases away from the town, and the digging of a trench to channel away the CO2. A few people remained to carry out essential functions and to salvage belongings from threatened houses. by. At 01:00 on 23 January 1973, a volcanic eruption of the mountain Eldfell began on Heimaey. The recovery and reconstruction of Heimaey was paid for by all Icelanders via a hypothecated sales tax, as well as through international aid totalling USD2.1 million, primarily from Denmark but with substantial contributions from the USA and several international organisations. The onset of the eruption was therefore almost entirely unexpected. The eruption finally came to an end in early July, when flowing lava was no longer visible, although subsurface flows may have continued for a few days longer. Causes and Information of the 1973 Eruption: The maroon Eldfell volcano - the Fire Mountain - was created in the volcanic eruption of 1973, in the Westman islands. They also used some of the extensive tephra (airborne volcanic material) fall to extend the runway at the island's small airport, and as landfill on which 200 new houses were built. Be the first to submit your climbing note! Eruption of the newly-formed Eldfell Volcano on the island of Heimaey in the Vestmannaeyjar (Westman Islands) south of Iceland, 150 meters from the town of Vestmannaeyjar. The Vestmannaeyjar (Icelandic for Westman islands) archipelago lies off the south coast of Iceland, and consists of several small islands, all formed by eruptions in the Holocene epoch. Wooden supports for the pipes caught fire where the lava was hottest, and even aluminium supports melted, but the pipes themselves were prevented from melting by the cold seawater flowing through them. It is believed that as least some of the CO2 originated deep within the volcanic conduit and percolated through older volcanic rocks, rising directly into the town. The explosive activity is now intermittent and the estimated lava production is less than 5 m 3 per second. The first boats left for Þorlákshöfn at about 02:30, just half an hour after the start of the eruption. Short-lived submarine activity was discovered by a fishing vessel on 26 May, about 4km north-east of Heimaey and 1km off the coast of the mainland. The 1973 Icelandic eruption caused a major crisis for the island and nearly led to its permanent evacuation. Eldfell Volcano Loop is a 3.3 mile moderately trafficked loop trail located near Vestmannaeyjar, Southern, Iceland that offers scenic views and is rated as moderate. Many houses were destroyed by the weight of the ash fall, but crews of volunteers working to clear the ash from roofs and board up windows saved many more. In July 1998 I returned to Heimaey to see the changes on the island over the 25 years and to document the changes with video. Eldfell is a cinder cone volcano just over 200 m high on the Icelandic island of Heimaey. The first attempt to slow the lava flow by spraying the leading edge with sea water began on 7 February, and although the volume of water being pumped on was rather small at 100 litres/s, the flow was noticeably affected. Fortunately, the lava flows and tephra fall did not at first affect the island's airstrip, and a few people who were unable to travel by boat were evacuated by air. When the Eldfell volcano exploded on Heimaey in 1973, people had to flee in an instant. With the harbour improved by the new lava breakwater, the fishing industry regained its former vigour and the island today remains the most important fishing centre in the nation. Eldfell is a cinder cone 200m high on the island of Heimay in the Vestmann islands off the south west cost of Iceland. The eruption caused a major crisis for the island and nearly led to its permanent evacuation.

Vestmannaeyjar: Eldfell volcano (in background) is erupting and fountaining lava. The evacuation was necessary because lava flows were already moving slowly into the eastern side of town, and the whole of the small island was threatened by the likelihood of heavy ash fall. 2. Lava flows had been sprayed with water in attempts to slow them in Hawaii and on Mount Etna, but these had been rather small-scale operations with limited success. Heimaey, the largest island in the group and the only inhabited one, also contains some material from the Pleistocene era. The eruption had made headlines around the world when it began, and was covered constantly by Icelandic news crews throughout. In the end, the harbour entrance was narrowed considerably but not closed off, and the new lava flow acted as a breakwater, actually improving the shelter afforded by the harbour. As usual for a fissure eruption the crater row developed into a single active crater in the middle of the rift. One that erupted around 6000 years ago and then we have Eldfell that erupted in 1973 and all of our inhabitants needed to leave the islands from the mainland. Houses close to the rift were soon destroyed by lava flows and tephra fall. Houses close to the rift were soon destroyed by lava flows and tephra fall. Many houses were destroyed by the weight of the ash fall, but crews of volunteers working to clear the ash from roofs and board up windows saved many more. Once the fireworks finished, heat from the volcano provided Heimaey with geothermal energy from 1976 to 1985. This pre-planned evacuation route resulted in no lives being lost from the eruption; even though the natural disaster came without warning, the community was still prepared. Mount Eldfell, 200 meters high, formed a volcanic eruption on the 23rd January 1973, just outside the town of Heimaey. Eldfell is a volcano in the Westman Islands, off the South Coast of Iceland, which famously erupted in the middle of the town of Heimaey in 1973. Since the settlement, no eruptions had been known to occur on the islands until 1963, when a new member of the archipelago, Surtsey, was formed by a four year eruption which began offshore about 20 km (12.5 miles) south-west of Heimaey. By the end of January, tephra covered most of the island, reaching 5 metres (16 ft) deep in places. Man Against Volcano: The Eruption on Heimaey, Vestmannaeyjar, Iceland. Large expanses of flow became encrusted with extensive white deposits, and it was estimated that up to 220,000 tonnes of salt was deposited in total. The chunk, dubbed Flakkarinn (The Wanderer), would have seriously threatened the viability of the harbour if it had reached it, and the dredging boat Sandey was brought in on 1 March to prevent its advance. The country lies on two tectonic plates along which the volcanoes are located: the Eurasian and North American plates.
