Inside the magma chamber

Þríhnúkagígur (Icelandic pronunciation:  [ˈθr̥iːˈn̥uːkaˈciːɣʏr̥] , anglicized as Thrihnukagigur, literally translated as Three Peaks Crater) is a dormant volcano in the volcanic system of Brennisteinsfjöll near Reykjavík, Iceland. [1] Covering a 3,270 square metres (35,200 sq ft) area and a depth of 213 meters (699 ft), [2] it has not erupted in the past 4000 years. [3] It was discovered in 1974 by cave explorer Árni B Stefánsson, and opened for tourism in 2012. It is the only volcano in the world where visitors can take an elevator and safely descend into the magma chamber. The magma that would normally fill the chamber and become sealed is believed to have drained away, to the bewilderment of most scientists, revealing the rift beneath the surface. [4]

In August 2015, the members of the Icelandic band Kaleo and fourteen support staff descended into the volcano's magma chamber and recorded a live rendition of the band's song "Way Down We Go". [5] [6]

In 2016, the Secret Solstice music festival announced that alternative rock musician Chino Moreno of Deftones will perform the first ever public concert inside the magma chamber of a volcano. [7]

A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber/reservoir in a volcanic eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. The ground surface then collapses downward into the emptied or partially emptied magma chamber, leaving a massive depression at the surface. Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Only seven caldera-forming collapses are known to have occurred since 1900, most recently at Bárðarbunga volcano, Iceland in 2014.

Deftones American alternative metal band

Deftones is an American alternative metal band formed in Sacramento, California in 1988. It was formed by Chino Moreno, Stephen Carpenter, Abe Cunningham (drums) and Dominic Garcia (bass). During their first five years, the band's lineup changed several times, but stabilized in 1993 when Cunningham rejoined after his departure in 1990; by this time, Chi Cheng was bassist. The lineup remained stable for fifteen years, with the exception of keyboardist and turntablist Frank Delgado being added in 1999. The band is known as one of the most experimental groups to have come from the alternative metal scene, and are sometimes dubbed by critics as "the Radiohead of metal".

White Pony was also the first album to feature Frank Delgado as a full-time member of the band on turntables and synthesizer; Delgado had previously worked with the band as a featured guest on Around the Fur (1997) and Adrenaline (1995), producing sound effects on some songs. It was also the first Deftones record which Chino Moreno began to contribute rhythm guitar parts.

Eros is the working title of an unreleased album by American alternative metal band Deftones, with tentative release dates in 2008 and 2009. The November 2008 car accident of bassist Chi Cheng forced the band to initially hold off on releasing the album, and later shelve the album indefinitely in a creative decision to move forward. With Cheng in a coma, Deftones recruited former Quicksand bassist Sergio Vega and released Diamond Eyes instead in 2010. In the years that followed, the band has had mixed feelings about finishing and officially releasing Eros at some point down the road. The recording sessions of this album marked the first time in five years, since their self-titled fourth album, that Deftones had worked with Terry Date.

Lava cave Cave formed in volcanic rock, especially one formed via volcanic processes

A lava cave is any cave formed in volcanic rock, though it typically means caves formed by volcanic processes, which are more properly termed volcanic caves. Sea caves, and other sorts of erosional and crevice caves, may be formed in volcanic rocks, but through non-volcanic processes and usually long after the volcanic rock was emplaced.

2010 eruptions of Eyjafjallajökull Volcanic events in Iceland

The 2010 eruptions of Eyjafjallajökull were volcanic events at Eyjafjallajökull in Iceland which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010. Additional localised disruption continued into May 2010. The eruption was declared officially over in October 2010, when snow on the glacier did not melt. From 14–20 April, ash from the volcanic eruption covered large areas of Northern Europe. About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travellers.
