Mount Eldfell, 200 meters high, formed a volcanic eruption on the 23rd January 1973, just outside the town of Heimaey. Submarine activity also occurred just offshore at the northern and southern ends of the fissure. 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 tremors continued at a reduced rate until 11:00 on 22 January, after which they stopped until 23:00 that evening.

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 lava which came from the volcanoes on the plate borders formed the island. 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. There was some underwater volcanic activity during the ongoing eruptions, which caused the water pipeline to Heimaey to break. The eruption caused a major crisis for the island and nearly led to its permanent evacuation. 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).

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. Rough tracks were made onto the flow by bulldozing tephra, but these tracks quickly became very uneven and moved several metres a day. 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. 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. by. The trail is … 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. 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. Nearly all of the island’s 5,300 residents were evacuated by fishing boats to the mainland, and they temporarily could not return. The volume of lava being emitted during the eruption fell steadily after the first few days. These defences were only partially effective, as they relied on the assumption that the gases were produced at the vent, and flowed into the town from there.

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. 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. 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. 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. There is no protection from the sun. After these pumps began to cool the flow advancing towards the town, its movement slowed dramatically and soon stopped. The efforts of the islanders to halt the lava flows received particular attention, with coverage in publications such as National Geographic (e.g. Once the fireworks finished, heat from the volcano provided Heimaey with geothermal energy from 1976 to 1985.

This type of volcano is generally a steep sided, symmetrical cone of large dimensions. 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. 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. 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. Professor Sigurgeirsson provided advice to the pumping crews on where to direct their efforts to most efficiently slow the flows. 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.

The threat of lava flows cutting off the harbour was the most significant facing the town. Following the end of the eruption, scientists began to assess the feasibility of extracting geothermal heat from the gradually cooling flows. A few people remained to carry out essential functions and to salvage belongings from threatened houses. The onset of the eruption was therefore almost entirely unexpected. 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. 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. 32 pumps were brought in from the USA, which had a capacity of up to 1000 l/s.

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. Following the end of the eruption, the islanders used the heat from the slowly cooling lava flows to provide hot water and generate electricity. Apart from falling ash, some houses were also burned down by fires caused by lava bombs, or overridden by advancing lava flows. Because of severe storms in the days before the eruption, almost the entire fishing fleet was in the harbour, a stroke of luck which greatly assisted the organisation of the rapid evacuation. The resourceful local people pumped seawater onto the lava which diverted the … The work involved in laying pipes over an active lava was highly dangerous, with low visibility due to the extensive emission of steam.

The fissure rapidly extended to a length of 2 km (1.25 miles), crossing the island from one shore to the other. 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. Although several men sustained minor burns, no serious injuries were received. 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 eruption started next to Vestmannaeyjabær town, on Heimaey island, and all the inhabitants of the island had to flee to the mainland of Iceland. The ensuing lava-cooling operations were the most ambitious that had ever been undertaken. By mid-1974, about half the pre-eruption population had returned to the island, and by March 1975, about 80% had returned. As Heimaey was responsible for some 25% of Iceland's total annual catch, the effect on the whole country's economy would be significant.

Spectacular lava fountaining occurred along the whole fissure, which reached a maximum length of about 3 km (2 miles) during the first few hours of the eruption, but activity soon became concentrated on one vent, about 0.8 km (0.5 miles) north of the old volcanic cone of Helgafell and just outside the eastern edge of the town. By the end of the eruption, Eldfell stood about 220 m (720 ft) above sea level. The water cooling of the lava was slow, but achieved a maximum efficiency, with almost all the water being converted to steam. Apart fr… The decline was slower after that, but by the middle of April the flow rate had fallen to about 5 m³/s. 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.

First an eruption fissure, about 1,500 m long, opened seawards only about 200 – 300 meters from the easternmost part of the town. Eldfell: Eldfell is a very small volcano, only around 650 feet high, on the Icelandic island of Heimaey. The explosive activity is now intermittent and the estimated lava production is less than 5 m 3 per second. Scientists have speculated that volcanic activity in the archipelago may be increasing due to the southward propagation of the rift zone which crosses Iceland. Eruptions are a big part of Westman Islands history and on the islands there are 2 Volcanoes. Up to three acres of lava flow could be cooled at one time, with internal barriers then being created within the flow, which thickened and piled up upon itself. The Heimaey Eruption: Iceland 1973 documented the battle to save the town from the volcano, Eldfell. The area of the lava flow is 2.1 km 2, and the average thickness is about 70 m.
