Recent Icelandic rifting events have illuminated the roles of centralized crustal magma reservoirs and lateral magma transport, important characteristics of mid-ocean ridge magmatism. A consequence of such shallow crustal processing of magmas is the overprinting of signatures that trace the origin, evolution and transport of melts in the uppermost mantle and lowermost crust. Here we present unique insights into processes occurring in this zone from integrated petrologic and geochemical studies of the 2021 Fagradalsfjall eruption on the Reykjanes Peninsula in Iceland. Geochemical analyses of basalts erupted during the first 50 days of the eruption, combined with associated gas emissions, reveal...

Lava Destroyed the Dike! Huge Lava Eruption in Iceland. Fagradalsfjall Volcano Eruption / May 22, 2021. Lava from Geldingadalir has broken through the dike wall and is pouring down into the valley below. Video here.

New Fissure Erupted at Fagradalsfjall More awesome live cam coverage.

A webcam is broadcasting live from Fagradalsfjall, facing Geldingadalur, where a fissure eruption began Friday night, 19th March. RÚV engineers worked through the night to revive the previously-popular earthquake monitoring webcam and to re-orientate it towards the volcano. It was previously located on Borgarfjall when scientists believed an eruption was most likelt at Nátthagi. Saturday morning (20th March), the camera was moved and is now on Fagradalsfjall, facing Geldingadalur. It is over a month since an earthquake swarm started on the Reykjanes peninsula in late February and a magma dyke started to form below the surface -- first from Keilir...

Below is a live cam covering a possible imminent eruption that scientists predict to make it to the crust in the next few hours. This was announced by the Icelandic Civil Protection Agency March 3rd 16:00 GMT: Update March 3rd 23:00 GMT: The tremor pulse was detected at 14:20 and is measured at most seismic stations in Iceland seems to decreased but many earthquakes are still being measured. No sign of eruption when Icelanders go to sleep.

“Unprecedented,” say experts. Look at the number of earthquakes in the last 48 hours! Southwestern Iceland was rocked by a series of earthquakes Wednesday. According to geological experts, the epicenter of the main quake was located near Mt. Keilir, roughly 30 km (19 miles) south of the capital Reykjavik. Experts say shocks from the quake, which registered 5.7 in magnitude, sparked increased volcanic activity, triggering a number of aftershocks registering over 4.0 for hours after the initial quake hit. “I’ve never experienced or felt so many strong earthquakes in such a short period of time. It’s unusual,” Icelandic Meteorological...

A region of Iceland is erupting for the first time in 800 years, raising concern of disruptions in air travel for centuries to come. The Guardian of London reported that since Jan. 21, the Reykjanes peninsula southwest of Iceland's capital, Reykjavik, has experienced more than 8,000 earthquakes. About 10 centimeters of land has risen due to magma intrusions underground, the paper said. "It seems that after being relatively inactive for many centuries, this region is waking up," Lancaster University volcanologist Dave McGarvie told the Guardian. The area is fed by five volcanic systems, the Guardian said, "which seem to come...

The seismo-volcanic crisis on Reykjanes Peninsula, Iceland continues on March 11, 2021, with more than 35 000 earthquakes detected since February 24, 2021. The probability of an eruption is increasing and the most likely place where it might start is from Keilir to Fagradalsfjall. The Scientific Council for Civil Protection met at a teleconference on March 10, concluding that as the current situation lasts longer, the probability of an eruption increases. Processing of satellite images received on the morning of March 10 and the latest GPS measurements, confirm that magma is still restricted at the southern end of the magma...

A powerful earthquake swarm continues on the Reykjanes Peninsula, Iceland since February 24th. Over 20.000 earthquakes have now been detected since the beginning of the earthquake swarm. As the series of strong earthquakes continues, more signs of magma movement are also being detected. This has prompted the officials monitoring the situation, to raise the alert level from yellow to orange.

Iceland eruption could mark the beginning of a volcanic period lasting a few centuries David Hartley Interesting article in the Iceland Monitor about eruptive phases on Iceland. What caught my eye was the fact it settled round about 1300 which Wiki has as round about the beginnings of the Little Ice Age. “If an eruption occurs, it would likely mark the beginning of such a [volcanic] period – lasting a few centuries (emphasis added), I believe,” states Magnús Á. Sigurgeirsson, geologist at ÍSOR Iceland GeoSurvey – a consulting and research institute in the field of geothermal sciences and utilization. Research...

Scientists in Iceland have said there are now “strong signs” that a volcanic eruption may be under way following several days of near-constant seismic activity near Mount Keilir about 20 miles south of the capital, Reykjavik. “We are not saying we have signs an eruption has begun,” Kristín Jónsdóttir of the Icelandic meteorological office told local media on Wednesday. “But this looks like the type of activity we expect in the run-up to an eruption.” 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...

Grímsvötn volcano on Iceland produced an unusually large and powerful eruption in 2011, sending ash 20 kilometres into the atmosphere, causing the cancellation of about 900 passenger flights. In comparison, the much smaller 2010 eruption of Eyjafjallajökull led to the cancellation of about 100,000 flights. Grímsvötn is a peculiar volcano, as it lies almost wholly beneath ice, and the only permanently visible part is an old ridge on its south side which forms the edge of a large crater (a caldera). And it is along the base of this ridge, under the ice, that most recent eruptions have occurred. Another...

The number of earthquakes detected in Iceland has already increased to 9,000. The series of earthquakes began as scientists in the country reported signs of activity from Iceland’s most active volcano. In its latest report, the Icelandic Meteorological Office (IMO) noted that it had detected a total of 9,000 earthquakes as of June 29. According to the agency, the earthquake swarm began on June 19 in areas northeast of Siglufjörður, which is a fishing town located on the northern coast of Iceland. Three of the earthquakes detected by the agency had magnitudes of over five. “The earthquake swarm began on...

Finally! The eruption comes following more than 40,000 earthquakes in the past four weeks, a huge jump from the more normal 1,000-3,000 earthquakes per year since 2014. The volcanic eruption began in southwestern Iceland near the capital Reykjavik on Friday, the country’s meteorological office said. A red cloud lit up the night sky after the eruption began in Fagradalsfjall, a mountain about 40km (25 miles) south west of Reykjavik. The Icelandic Meteorological Office said all inbound and outbound flights from Keflavik airport in Reykjavik have been halted. It is the area’s first volcanic eruption in nearly 800 years (some say...

A long-dormant volcano in southwest Iceland erupted on Friday 25 milesfrom the capital Reykjavik, the Icelandic Meteorological Office said. Local media reported inbound and outgoing air traffic had been halted from Keflavik International Airport, the country's largest, servicing the capital. The eruption followed thousands of smaller earthquakes in the area in recent weeks, with officials bracing for an eruption as a result. 'Color code red' "We ask people to stay calm and not under any circumstances go close to the eruption site or on Reykjanesbraut. First responders need to be able to drive freely to assess the situation. Scientists are...

A volcano has erupted in Iceland about 40km (25 miles) from the capital Reykjavik, the Icelandic meteorological office has said, as a red cloud lit up the night sky and a no-fly zone was established in the area. “Volcanic eruption has begun in Fagradalsfjall,” it said in a tweet on Friday night, referring to a mountain located about 30km south-west of the capital. Police and coastguard officials raced to the scene late on Friday and the public has been advised to stay away from the area.
