One of the cauldrons in the ice cap of Vatnajökull above the monster volcano Bárðarbunga.
A sharp earthquake swarm was detected in the Bárðarbunga caldera early morning today, Monday. A 3.0 magnitude quake, with an epicenter 7.6 km (4.7 mi) east of Bárðarbunga peak, on the eastern edge of the caldera of the central volcano, at a depth of 3.4 km (2.1 miles) was detected at 6:09 in the morning. Half a dozen smaller aftershocks were detected.

The Bárðarbunga system has been showing increasing levels of activity for the past year or so, following the 2014-15 Holuhraun eruption at the northern edge of the system.

Hot spots at Barren Island volcano suggesting lava flows from the crater on the northern flank of the cone
A new eruption seems to be going on at the remote island (the only active volcano of India): since around 25 Sep, a strong thermal signal has been visible on satellite data and suggests lava flows on the north flank of the active cone, probably reaching the NW coast.

Anak Krakatau erupted 44 times
With the 45+ eruptions at Krakatoa in Indonesia over the weekend and the Minbu Mud Volcanoes in Myanmar starting to uptick, makes you wonder what is happening under the plate and if it is on regular cycles that can be mapped because volcanic eruptions are one event that occurs during Grand Solar Minimums.

Krakatoa volcano stirs to life

The volcanic island of Krakatau (previously called Krakatoa) is situated in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The name is also used for the surrounding island group comprising the remnants of a much larger island of three volcanic peaks which was obliterated in a cataclysmic 1883 eruption.

In 1927, a new island, Anak Krakatau, or "Child of Krakatoa", emerged from the caldera formed in 1883 and is the current location of eruptive activity.

In the NASA photos below, you can see some stunning images of the volcano as it's been stirring to life again

Popocatepetl volcano
Popocatépetl volcano has erupted, with smoke visible across the state of Puebla.

Residents have been warned not to travel within seven-and-a-half miles of the active volcano.

Witnesses reported an "explosion" at around 5pm BST before smoke and ash began billowing out of the volcano.

Shock photos show the smoke visible from miles around - even from built up nearby towns.

Fake News: Volcanologist blasts The Sunday Times for Katla volcano fearmongering

Scientists decried the current media alarmism invoking the Eyjafjallajokull eruption in 2010.
A Russian-Icelandic volcanologist has exploded on Twitter, berating the news media for exaggerating her research into Iceland's Katla volcano by claiming that it was due to erupt soon, dwarfing previous major eruptions.

"Incredibly disappointing to see that The Sunday Times have gone down the route of trashy tabloids," the Russian-born, Iceland-raised and Cambridge-educated volcanologist Evgenia Ilyinskaya wrote in a lengthy Twitter tirade, excoriating the news media's coverage, following the publication of an interview she gave about her recently published research.

"This article misinforms their readers and undermines me as a scientist and a specialist in my field," Ilyinskaya added.

Deadly 'Child of Krakatau' volcano erupts 56 times in one day in Indonesia

An Indonesian volcano called Anak Krakatau, known as the ‘child’ of the legendary Krakatoa, erupted on July 19, 2018, spewing a plume of ash high into the sky as molten lava streamed down from its summit.
A volcano in Indonesia known as the "Child of Krakatoa" erupted over 50 times in a single day, according to meteorologists and geophysics experts.

Staff at MAGMA Indonesia (Multiplatform Application for Geohazard Mitigation and Assessment in Indonesia) noted in a Sept. 23 statement that Mount Anak Krakatau, or "Child of Krakatoa," erupted 56 times on Sept. 22, spewing lava and ejecting dark smoke.

"Crater smoke is thin white to gray, with a thin to thick intensity, reaching a height of 1000 meters (3280 ft). A total of 56 eruptions with a height of 200-300 m (656-985 ft) have been observed, along with black smoke. Night-time footage from CCTV showed lava flares and incandescent flow."

Thunderous sounds and weak tremors accompanied the eruption, MAGMA Indonesia stated, adding that tourists and other people were prohibited from approaching the crater within a 2 km (1.2 miles) radius.

Iceland's Katla volcano charging up for eruption

The Katla volcano, hidden beneath the ice cap of Mýrdalsjökull glacier in Iceland, has historically erupted violently once every 40-80 years. In-as-much as it's last such eruption took place one hundred years ago, in 1918, Katla's next eruption is long overdue.

AN ICE CAULDRON IN MÝRDALSJÖKULL Geothermal activity in the volcano’s caldera melts the glacier, creating cauldrons in the ice.
An eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption, scientists have warned.

Scientists observe ice thickening above 'inactive' volcano in Antarctica

Unusual iceberg

Unusual iceberg at Rothera Research Station, Antarctic Peninsula.
A region of West Antarctica is behaving differently from most of the rest of the continent: A large patch of ice there is thickening, unlike other parts of West Antarctica that are losing ice. Whether this thickening trend will continue affects the overall amount that melting or collapsing glaciers could raise the level of the world's oceans.

The track hidden in the middle of the ice sheet suggests that the current thickening is just a short-term feature that may not affect the glacier over the long term, the new study indicates. It also suggests that similar clues to the past may be hiding deep inside the ice sheet itself.

SHUTTING IT DOWN

"What's exciting about this study is that we show how the structure of the ice sheet acts as a powerful record of what has happened in the past," says first author Nicholas Holschuh, a postdoctoral researcher in Earth and space sciences at the University of Washington.

The data come from the ice above Mount Resnik, a 1.6-kilometer (mile-high) inactive volcano that currently sits under 300 meters (0.19 miles) of ice. The volcano lies just upstream of the thickening Kamb Ice Stream, part of a dynamic coastal region of ice that drains into Antarctica's Ross Sea.

Reunion Volcano is erupting

Reunion Volcano
The 'Piton de la Fournaise' of Reunion Island, a French Indian Ocean Territory erupted at 4:25 am on Saturday, September 15, 2018.

The lava gushed on the south flank of the volcano in the 'Rivals' crater area. According to the volcanological observatory the seismic crisis began at 1:45am.

The volcano had given signs of awakening since the beginning of September. The eruption is visible from Piton Bert.

According to the information provided by the volcanological observatory, "the volcanic eruption is boxed in and limited to the 'Fouqué' enclosure, where the eruptive fissures have opened on the southern flank of the volcano in the region of the crater Rivals".

At least one crack of about 500 meters opened just below the site of the April 27, 2018 eruption.
