Reykjanes Volcano Update: Magma pooling again at depth, overflight of the eruption's aftermath

mmmm
The 49 hour eruption of Iceland's Reykjanes volcano has come to an end. However, magma is once again pooling at depth, and could be setting the stage for another magmatic intrusion 1 to 2 months from now. This video will show what the lava field from Iceland's newest eruption looks like, via an overflight from a remotely operated drone.

Best of the Web: Iceland volcano erupts! 4km-long, glowing-red fissure opens on same peninsula as capital Reykjavik


Comment: No media reports mention that this thing is located but a few miles from Iceland's capital! Never good to be that confident with what natural disasters will or won't do...

A volcano on the Reykjanes peninsula in south-west Iceland has erupted after weeks of intense earthquake activity, spewing glowing orange jets of lava surrounded by billowing clouds of red smoke.

"Warning: eruption has started north of Grindavík by Hagafell," the meteorological office said on its website on Monday. The eruption started a few kilometres from Grindavík, a fishing town located about 25 miles (40km) south-west of Iceland's capital, Reykjavík. The town with a population of 4,000 was evacuated in November after the area was hit by a "seismic swarm" of more than 1,000 small earthquakes in 24 hours.

The government on Tuesday said the eruption did not present a threat to life, adding that there were no disruptions to flights to and from Iceland, while international flight corridors remained open.

Indonesia's Marapi volcano erupts again, sending toxic ash and smoke 10,000 feet into the air

Indonesia's Marapi volcano erupted and sent more ash and toxic smoke high into the atmosphere on Tuesday, one week after the mountain came to life and exploded, killing at least 23 climbers.

According to the country's Centre for Volcanology and Geological Hazard Mitigation, West Sumatra's Mount Marapi, which stands at 9,251 feet, erupted early Tuesday morning local time and sent ash more than 10,000 feet into the air.

The eruption was relatively minor and nowhere near the intensity that was observed during last week's eruption.

Marapi first erupted on Dec. 3 and sent volcanic ash raining down on communities near the volcano, which "made the atmosphere in Nagari Lasi very thick and dark."

Best of the Web: Long dormant volcanoes can erupt rapidly and explosively, study of Ciomadul reveals

volcano crater
© István FodorCan a volcano erupt after tens of thousands of years of dormancy? If so, how can this be explained and what makes volcanic eruptions more dangerous, i.e., explosive? These are key questions in volcanic hazard assessment and can also draw attention to volcanoes that appear to be inactive. Even in a quiet, dormant phase, a volcano can rapidly become active, and its eruption can pose a previously unknown threat to the surrounding area. New research by Hungarian scientists is helping to reveal the signs before such a volcano erupts.

A team from the ELTE Eötvös Loránd University, Institute of Geography and Earth Sciences, and the HUN-REN-ELTE Volcanology Research Group, in cooperation with other scientists from Europe, studied Ciomadul, the youngest volcano in the Carpathian-Pannonian region.

Mount Marapi: Eleven hikers killed as volcano erupts in Indonesia - death toll increases to 22 (UPDATE)

nnnnnnnn
Eleven hikers have been found dead near the crater of Indonesia's Mount Marapi volcano after it erupted over the weekend, rescuers say.

Twelve others are missing and the search was suspended on Monday after another, smaller eruption.

There were 75 hikers in the area during the main eruption on Sunday but most were safely evacuated.

Marapi spewed a 3km (9,800ft) ash cloud into the air, dimming the sky and blanketing surrounding villages in ash.

It is among the most active of Indonesia's 127 volcanoes and is also popular among hikers. Some trails reopened only last June due to ash eruptions from January to February. Marapi's deadliest eruption occurred in 1979, when 60 people died.

Three people were rescued near the crater on Monday before the search was suspended. They were "weak and had some burns", said Abdul Malik, head of the Padang Search and Rescue Agency.


Comment: Update December 5

The BBC reports:
The death toll from a volcanic eruption in Indonesia has gone up to 22, after rescuers found nine more bodies.

The search for the 10 missing hikers on Mount Marapi resumed on Tuesday after being paused due to safety worries.

Officials said that nine bodies had been recovered by afternoon, with one of them still missing. Twelve other injured hikers are undergoing treatment in hospital.

Frequent volcanic eruptions in Marapi have hampered rescue efforts for days.

Ahmad Rifandi, head of Marapi's monitoring post, told AFP news agency that five eruptions had been recorded on Tuesday alone.

"Marapi is still very much active. We can't see the height of the column because it's covered by the cloud," he said.

Rescuers told BBC News Indonesia they have been taking advantage of windows of relative calm to look for the missing and efforts to look for the last missing hiker would resume on Wednesday.

Etna erupts again, sending hot lava down its snowy slopes

Mount Etna on the Italian island of Sicily erupted at dawn on Friday, creating a festive spectacle of fire and ice.

At 3,3057 metres, it's Europe's tallest volcano and has been constantly active in the past ten years.

But no one has been injured and no one is in danger.

Volcanologists have described the activity on Etna in recent days as a succession of Strombolian eruptions - which are moderately explosive but short eruptions named after the volcano on the nearby island of Stromboli.

Mount Anak Krakatau erupts, sparks panic

mmmmmm
Mount Anak Krakatau, situated in the waters of the Sunda Strait, South Lampung Regency, erupted again this afternoon, Nov. 27, sending a massive ash plume approximately 2,000 meters above the summit or around 2,157 meters above the sea level.

According to the Volcanology and Geological Disaster Mitigation Center (PVMBG), the eruption occurred on Monday at 11.43 a.m. local time and was recorded on a seismogram with a maximum amplitude of 77 millimeters for 116 seconds. The thick gray-black ash column was moving northwest.

The volcano had earlier erupted at 9:32 a.m., spewing ash columns about 1,500 meters above the summit or 1,657 meters above sea level.
