Bogi Adolfsson, director of the Þorbjörn Search and Rescue team in Grindavík says the lava flow is expected to flow over more of the current hiking path and authorities have approved the preparation of a new trail to the eruption which will become the main path. The end of the path is now inaccessible as lava has surrounded what was once the main lookout over the erupting crater. 7:00 AM The Little Icelandic Town That Survived an Epic Lava Flow In 1973, a massive fissure ripped open the earth near the tiny town of Vestmannaeyjar. Authorities have also created temporary parking lots at the site and marked a hiking path. ![]() Since the eruption began, Search and Rescue crews have been monitoring the area to ensure visitor safety.

Then it gushes over and that just adds to the covering,” Þorvaldur Þórðarson, Professor at the University of Iceland’s Institute of Earth Sciences (University of Iceland) told mbl.is. Especially this channel, it’s being covered up bit by bit. “Now the crater is closing little by little. The third period encompasses the past seven weeks, during which the lava flow has been emerging from a single, large crater and has increased from 5-8 cubic metres per second to as much as 13. The blue-tinged volcanic gas emissions are one of the main hazards associated with this eruption. Lava erupts from the fissure on the northern edge of the 2021 eruption flow field (black lava in upper right). The eruption started on Monday in a valley near the Litli-Hrtur. ![]() The second period began in April, and was characterised by new vents opening to the north of the first craters and a flow of 5-8 cubic metres per second. An aerial view of the recent eruption on Reykjanes Peninsula, Iceland, taken during an eruption surveillance flight. Lava is seen flowing following a volcanic eruption near Iceland's capital. ![]() During the first two weeks, the eruption had a steady though slightly diminishing flow that started at around 7-8 cubic metres per second and slowed to 4-5 cubic metres per second. Geologists have identified three distinct periods of activity since magma broke the surface. The Geldingadalir eruption began on Iceland’s Reykjanes peninsula nearly three months ago on March 19, 2021. The eruption has become a popular tourist site and authorities have already approved the preparation of a new hiking path as lava is expected to flow across the one currently used by visitors. The fears that this eruption would flow out of the valley towards the. The eruption seems to be developing into what’s known as a shield volcano, a formation created by lava flowing slowly over a long period. This eruption lasted until the 21st August 2022 and filled the valley with fresh lava. The main active crater is slowly closing up as lava accumulates and cools around the opening. Story by Kathryn Hansen.Most of the lava flowing from the Geldingadalir eruption is below the surface and entirely hidden from view. For the first time in almost 5,000 years, people in Reykjavik can experience lava flows in the heart of the city thanks to a new show that’s proving a massive hit with visitors. NASA Earth Observatory image by Joshua Stevens, using Landsat data from the U.S. ![]() Measurements on May 10 indicated that the lava discharge rate was increasing, reaching 13 cubic meters per second.Īccording to a video by Reykjavík Newscast, the nearby town of Grindavík has voted to name the lava field Fagradalshraun: beautiful valley lava. Making this phenomenon even more exciting was its location. Notice the lava (red) actively pouring from one of the vent systems.Ī volcano activity update from the Icelandic Met Office on May 12 noted that the vents associated with this eruption have spilled nearly 30 million cubic meters of lava since the start of the eruption in late March. For nearly a year within the Geldingadalur valley, gleaming lava spurted and flowed from Fagradalsfjall volcano, and as of July 2023, another one has started close to the mountain Litli-Hrutur. Dark brown areas indicate where cooling lava has piled up and spread across valley floors. The Operational Land Imager (OLI) on Landsat 8 acquired this image around midday on May 9, 2021. This natural-color satellite image shows the volcano by daytime, with a rare clear view of the eruption and the geologic features of the landscape. The eruption at Fagradalsfjall volcano in southwestern Iceland has put on quite a show this year, lighting up the night sky and even appearing to influence the clouds above it.
