Despite strong tremors in the area, much less ash and smoke were rising from the Iceland volcano that crippled European air travel for much of the past week.
As airports across Europe reopened Tuesday and the long process of returning thousands of stranded passengers to their homes began, the ongoing fallout of recent volcanic eruptions in Iceland delayed the delivery of polio vaccine to Africa and caused concern that another, more dangerous eruption could soon occur at another nearby volcano.
The volcanic eruption in Iceland that has crippled European air travel for days is now beginning to produce molten lava, meaning that less ash should be produced and raising hopes that the existing cloud that has forced flights to be grounded could finally start dispersing.
New techniques under development could provide better tracking of volcanic plumes.
As ash caused by a volcanic eruption crippled European air travel for a fourth straight day on Sunday, hope that the travel restrictions could soon be lifted came in the form of a few successful test flights.
In the past, volcanic eruptions have had a cooling effect on the Earthâ€™s climate, but the recent Icelandic eruption is too small to provide any relief from manmade global warming.
Volcanic ash fall could contaminate Icelandâ€™s drinking water in certain areas due to the ongoing Eyjafjallajokull eruption.
Thousands of planes are grounded across Europe due to the spread of volcanic ash following the recent eruption under Iceland's Eyjafjallajoekull glacier.
Irazú Volcano, known as Volcán Irazú in Spanish, is an active stratovolcano that is located in Costa Rica. The origin of the volcano’s name is unknown, but it is thought to be a variant of the word Iztarú, which is the name of a village that was near the volcano, or a mixture of the words ara, meaning point, and tzu, meaning thunder. It is locally known as The Colossus due to large past eruptions. This volcano is located within Irazú Volcano National Park, which holds montane forests...
Rincón de la Vieja is an active complex volcano that is located in northwestern Costa Rica. Its name, meaning The Old Woman's Corner, refers to a legend that says that a woman’s lover was thrown into the volcano by her father, after which she lived on the volcano as a recluse. This volcano reaches 6,286 feet in elevation and is the tallest volcano in Rincón de la Vieja Volcano National Park. Visitors were once permitted to climb up to the crater, but a recent eruption caused this area to...
Mount Hudson, also known as Volcán Hudson, is an active stratovolcano that is located in southern Chile, named after 9th-century Chilean Navy hydrographer Francisco Hudson. Its summit, which is covered in glaciers, holds a caldera that was created from a large eruption that occurred in 4750 BCE or 1890 BCE. Based on evidence found at the Los Toldos archaeological site, it is thought that the early eruption destroyed most settlements in the area at that time. Modern eruptions occurred in...
Nyamuragira is an active shield volcano that is located in the Democratic Republic of the Congo. This volcano, which is part of the Virunga Mountains, reaches an elevation of 10,033 feet and is the most active volcano in Africa. This volcano is shorter than Nyiragongo, which it shares an area with, and has a low shield profile. It holds a large amount of sulfur dioxide and is blamed for much of the volcano related sulfur dioxide content in the atmosphere. Nyamuragira has erupted over forty...
Imbabura Volcano is an inactive stratovolcano that is located in Ecuador and is part of the southern Ring of Fire and one of many volcanoes created along an arc by the subductions of the Coolyo Plate underneath the South American Plate. This volcano was shaped by strombolian eruptions, which are less violent than plinian eruptions and are characterized by the expulsion of lapilli, lava bombs, and cinders as well as the accumulation of tephra around the point of eruption like a vent....
