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.

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.

"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.

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.
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 eruption in Katla would dwarf the 2010 Eyjafjallajökull eruption, scientists have warned.

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.

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.

THE 1918 ERUPTION: Katla erupts once every 40-80 years. Its last eruption was in 1918, making it 20-40 years overdue for an eruption.
A group of Icelandic and British geologists have recently finished a research mission studying gas emissions from the volcano. The studies showed that Katla is emitting enormous quantities of CO2. The volcano releases at least 20 kilotons of C02 every day. Only two volcanoes worldwide are known to emit more CO2, Evgenia Ilyinskaya a volcanologist wit with the University of Leeds told the Icelandic National Broadcasting Service RÚV.
These enormous CO2 emissions confirm significant activity in the volcano, Evgenia told RÚV: "It is highly unlikely that these emissions could be produced by geothermal activity. There must also be a magma build up to release this quantity of gas."
She points out that more studies are needed to determine if the gas emissions from Katla are stable, or if they are increasing. "It is well known from other volcanoes, for example in Hawaii and Alaska, that CO2 emissions increase weeks or years ahead of eruptions. This is a clear sign we need to keep a close eye on Katla. She isn't just doing nothing, and these findings confirm that there is something going on."
