The current pool of water at the bottom of the crater is at the same level as the water table and is not caused by rainfall. Once the magma was depleted, the weight of the cone collapsed into the empty magma chamber. It is now believed that Kerið was a cone volcano which erupted and emptied its magma reserve. PT Astra Honda Motor (AHM) meluncurkan produk terbarunya ke Tanah Air. Land owners charge an entrance fee to see the crater of 450 ISK (as of February 2023 ).Īlthough volcanologists originally believed Kerið was formed by a huge volcanic explosion, as is the accepted norm with volcanic craters, more thorough studies of the Grímsnes region failed to find any evidence of such an explosion in Kerið. The lake itself is fairly shallow (7–14 metres, depending on rainfall and other factors), but due to minerals from the soil, is an opaque and strikingly vivid aquamarine. The mountain was formed during the Ice Age, underneath a glacier and is classed as a hyaloclastite mountain, although scientists believe it to actually be the plug. It can be easily visited when travelling between Reykjavk and Keflavk Airport, or the Blue Lagoon. While most of the crater is steep-walled with little vegetation, one wall is sloped more gently and blanketed with a deep moss, and can be descended fairly easily. Mount Keilir is a small volcanic mountain to the southwest of Hafnarfjrur. The other two are Seyðishólar and Kerhóll. Kerið's caldera is one of the three most recognizable volcanic craters because at approximately 6,500 years old, it is only half the age of most of the surrounding volcanic features. The caldera, like the other volcanic rock in the area, is composed of a red (rather than black) volcanic rock. It is one of several crater lakes in the area, known as Iceland's Western Volcanic Zone, which includes the Reykjanes peninsula and the Langjökull Glacier, created as the land moved over a localized hotspot, but it is the one that has the most visually recognizable caldera still intact. There is also a chance that road access to the airport could be cut off by lava flows, prompting authorities to draw up contingency plans to divert flights and passengers to the island’s other airports.Kerið ( Icelandic pronunciation: also Kerith or Kerid) is a volcanic crater lake located in the Grímsnes area in south Iceland, along the Golden Circle. “This will probably be a lava eruption with little explosive activity.”Īny lava flows near Mount Keilir are unlikely to reach populated areas, experts have said, but could interrupt air traffic to and from Keflavík international airport, which is about 12 miles from the main area of seismic activity and is on orange alert. “It is very unlikely that it will disrupt air transport,” he said. Redoubt Volcano Visible from the mouth of the Kenai River. “This event is completely different to Eyjafjallajökull,” Freysteinn said. That means there is unlikely to be a repeat of the chaos in 2010 when the six-day explosive eruption of the more southerly Eyjafjallajökull volcano caused huge disruption to international air travel, affecting as many as 10 million travellers. If magma reaches the surface, Freysteinn said, it is unlikely to be in the form of an explosion of lava and ash shooting into the sky, but rather what is known as a fissure eruption, in which lava emerges more slowly from a crack in the earth’s surface. Freysteinn Sigmundsson, a geophysicist, said that if it came, the eruption could also be delayed by several days. Thousands of tremors measuring up to 5 on the Richter scale have been recorded on the peninsula during the past week. There was no immediate danger, he said, although people should avoid travelling to the area on the Reykjanes peninsula. Víðir Reynisson of the island’s civil defence force told a mid-afternoon news conference it was “more likely than not” that an eruption – the first in the area since the 12th century – was about to begin, and could happen within the next few hours.īut Víðir said there was “no disaster going on and everyone can get on with their daily lives”.
