Where is it?Mount Nyamuragira and Mount Nyiragongo , Congo [ -1.46079851 , 29.22711414 ]
What ’s in the photo?Infrared images of lava lakes that emerge during simultaneous volcanic eruptions
The lava lakes of Nyamuragira (top) and Nyiragongo (bottom) glow red in this 2014 satellite image captured using infrared radiation.
Which satellite bring the photo?Landsat 8
When was it taken?June 30 , 2014
This salient , false - color satellite picture shows the intense heat come from a yoke of lava lake that emerged on simultaneously erupting volcano in Congo . The neighboring peaks are among Africa ’s most participating — and lethal — volcanoes .
The lava lake at the summit of Mount Nyiragongo has been the largest on Earth at several points during its ongoing eruption. This photo was taken in March 2018.
Mount Nyamuragira(top of image ) andMount Nyiragongo(bottom of figure of speech ) are rough 6 miles ( 10 klick ) aside and are settle just north of the city of Goma , which is nursing home to more than 1 million people .
Nyamuragira is a noodle - influence shield vent that stands up to 10,033 feet ( 3,058 cadence ) tall , while Nyiragongo is a stratovolcano , with a steep strobilus that predominate up to 11,385 fundament ( 3,470 molar concentration ) above ground level .
The orbiter exposure was taken a few week after Nyamuragira began erupting for the first metre since March 2012 . This bang cease in May 2016 , but the volcano has since had two more eruptions : from November 2016 to May 2017 , and again in April 2018 , which is still ongoing . Meanwhile , Nyiragongo has been ceaselessly erupting since May 2002 .
Nyamuragira (left) and Nyiragongo (right) are closely linked to one another. This graphic shows the differences in their respective topographies.

Sizeable lava lakes were spot at the summit of both volcanoes during the coincident eruptions . The lava lake at Nyiragongo is specially interesting because stratovolcanoes do not normally support these features . At various item over the last two decade , this fiery pool has been the biggest lava lake on Earth , according to a2021 study .
The image was seize in infrared , which makes the lava lake appear to glow red and give the surrounding flora a bright green colouration , according toNASA ’s Earth Observatory .
Double trouble
Nyamuragira and Nyiragongo both formed around 12,000 years ago during a period of increased activity along the Kameronze fault line , which lies directly between the two volcanoes , consort to the 2021 sketch . As a result , their bodily process is partially linked , despite being separate entities .
The volcano are highly fighting and have together with belch around 60 multiplication since 1900 . Together , the pair is believed to be responsible for around 40 % of Africa ’s recorded volcanic eruptions . And some of their most late outbursts have been particularly intense .
Nyamuragira is the more alive of the two volcano and has frequently spawn littler , irregular volcanoes on its flank . The most late was " Murara , " a clinker cone that emerged between 1976 and 1977 . The stack is also surround by old lava flows that spilled down its incline ( and are seeable in the satellite photo ) .
In November 2011 , a 1,300 - base - grandiloquent ( 400 m ) fountain of lava shot out of the erupt vent , according tolocal report . This is believe to have been the large individual tumultuous disturbance there for at least a century .
However , Nyiragongo is the closest to Goma and , therefore , the more dangerous of the duo . When lava flows spill down the volcano ’s exorbitant slopes , they can reach mellow fastness , giving locals small warning .

In January 1977 , the vent unleash the fastest lava flow in register chronicle , reaching speeds of up to 62 miles per hour ( 100 km / h ) , which wipe out around 2,000 people in Goma and the ring areas , according toGuinness World Records .
In January 2002 , a like eruption killed around 250 people and get extensive legal injury to place , leaving more than 100,000 people homeless and spark off a refugee crisis , concord toBritannica . The most recent incident occurred in May 2021 , when at least 31 people die , accord toCNN . However , in this case , several deaths resulted from traffic collisions as the great unwashed attempt to evacuate the area .
