Lava lakes of the world
The number of lava lakes in the world changes. Thus, over 2018-2019 disappeared three lava lakes that existed for decades.
As a result, in October 2019 we have seven existing lava lakes on Earth. Three more existed for a longer time in the recent past. Besides this, since the year 2000 short-lived lava lakes and lava ponds existed in 11 more places. Wondermondo has listed them all in this article.

What is a lava lake?
Sometimes in the volcanic vent (the opening through which erupt volcanic lava or gases) or in other low areas forms a large mass of molten rock – lava. In most cases, such lava lakes are short-lived because the lava cools down after the end of the eruption and turns into a rock. But in rare cases, lava lakes form in the volcanoes and “live” for decades and even centuries.
Such permanent lava lakes need quite special circumstances – a steady supply of lava and heat and good viscosity and homogeneity of lava. There is needed a constant stirring of the lava so that it does not cool off. This is achieved mostly by gases that leave the lava, creating impressive fountains.
Inaccessible lava lakes
These specific conditions meet only in a few places on Earth. Here an intriguing fact is that some of these lava lakes are in areas that are very hard to access. Sure, Erta Ale and Mount Erebus are in inhospitable areas that are not too inviting for a general tourist. But much, much worse is Mount Michael – here the elusive lava lake is well protected from visitors. Around the summit of this volcano is a thick layer of ice and snow. Walk there if you dare – but this thick layer of snow is half-melted, with countless cracks and caves in it. One extra step towards the crater – and the ground will collapse inevitably. Thus humans have not seen the lava lake of Mount Michael with their eyes – only through the satellite images. It is possible that at least one more such elusive lava lake exists on the Mawson Peak of Big Ben volcano on Heard Island.
Short-lived lava lakes and ponds in the 21st century
Several more lava lakes and lava ponds existed for shorter periods of time since 2000. Such features more often are called “lava ponds” and exist for a short while.
- Karthala in Comoros is quite active volcano. In April 2005 in Chahalé crater formed an impressive lava lake which after some days “froze”. Then, in November was a great, 60-80 m wide lava lake. A few weeks later it was “frozen” again. Similar short-lived episodes repeated on May 2006, January 2007. (9)
- Ol Doinyo Lengai – This unique carbonatite volcano in Tanzania often has had small, short-lived lava lakes, which have been registered in different lava cones in 2000, 2001, 2002, 2004, 2005, 2006, 2009, 2011, 2018. (7) Carbonatite lava melts at comparatively low temperatures and this is not a glowing red lava, but less impressive black liquid.
- Nabro Volcano in Eritrea, Danakil Depression had an unexpected eruption in 2011. Then, something similar to lava lake was noticed in the northern caldera of the volcano. (10)
- Piton de la Fournaise in Réunion often had short-lived lava lakes, which have been observed also in 2000, 2001, 2002, 2008, 2015, 2018, 2019. These were small ponds erupting lava flows and not long-lived lava lakes. (8)
- Pacaya – this Guatemalan volcano had lava lake in August 2000 – June 2001. The glow of the lake was visible from Guatemala City. (3)
- Telica in Nicaragua repeatedly had short-lived lava lakes – in 1971 and in the late 1999-early 2000. (5)
- Turrialba in Costa Rica had small lava lake in June 2017. There is no further information about the existence of it. (6)
Islands of the Pacific Ocean
- Pu’u ‘Ō’ō crater in Hawaii (not shown on the map – on Kilauea volcano close to Halemaumau) repeatedly had a lava pond in March 2002, July 2005, September 2008 – early 2009, March 2011 – early August 2011, August – September 2011, January – December 2013, January-August 2014, January 2017 – May 2018. Sometimes this smaller pond increased to a more significant size. (11)
- Tofua volcano in Tonga had a vent (named Lofia) with glowing lava in May-June 2006. This was a comparatively small pond of lava… but technically – also a lava lake. It has existed earlier as well, e.g. in 1993 and some characteristics of lava lake were observed also later, in 2009 and 2010. (4)
- Mawson Peak of Big Ben is located on the remote Heard Island. The last eruption took place here in 2008. Then satellite data showed that there is a lava lake with a diameter of 100-150 m. It is possible that this lava lake exists here up to this day.
- Mount Belinda is in South Georgia and South Sandwich Islands, Montagu Island. The lava lake was noticed here from the satellite in 2004 and, most likely, now does not exist anymore. The eruption of the volcano in 2002 – 2009 was quite impressive because it created a 90 m wide, subglacial river under the glacier.

Existing and recent lava lakes
Ethiopia, Afar Region, Danakil Depression
Size of the lake: Diameter – some 50 m
How long does it exist? 1967 – now
Erta Ale is typical shield volcano with gentle slopes, some 50 km wide but rising just for some 700 meters. Sometimes lava spills over the rim of the crater and in the night the glow of lava is seen far away from the volcano.
Nicaragua, near Masaya town
Size of the lake: 40 by 40 meters (early 2016)
How long does it exist? Current lava lake exists since the December 2015. Lava lakes have existed here earlier as well.
This volcano had the largest known lava lake in the world – in 1670 it was approximately 1 km wide! Current lava lake is very dynamic, with enormous bubbles and unusual speed of lava convection.
Antarctica, Ross Island
Size of the lake: Diameter of 40-60 m (there might be two lakes)
How long does it exist? At least since the discovery of volcano in 1841
The only active volcano with phonolitic lava on Earth. In 1984-1985 the glow of the lava lake in the night was seen from the distance of some 70 km.
South Georgia and South Sandwich Islands, Saunders Island
Size of the lake: Fluctuating between 90 and 215 m in diameter
How long does it exist? Known since around 1995
Lava lake has been known here since around 1995. Nevertheless, scientists got a full confidence about it only in the early 2019 and mass media often reported that this is a new discovery. People have seen only satellite images of this lava lake – none has ascended the summit of the volcano.
Democratic Republic of the Congo, Virunga Mountains
Size of the lake: Fluctuating
How long does it exist? Current lava lake appeared in April 2018, but lava lakes have existed here earlier
Nyamuragira is the most active volcano in Africa. It produces major part of sulfur dioxide pollution in the world. This impressive volcano is 3,058 m high.
Democratic Republic of the Congo, Virunga Mountains
Size of the lake: Diameter is fluctuating – around 250 m (currently the largest in the world)
How long does it exist? At least since 1948 but most likely – much longer
3,470 m tall volcano. It has a giant crater which is some 1.5 km wide and 500 m deep. There is a permanent lava lake in the crater which frequently has mighty fountains of lava in it. Sometimes lava lake overflows the rim of the crater and floods into the surrounding areas.
Chile, Araucania Region
Size of the lake: Intermittent lake. Width of the crater is 50 m but the lake is smaller.
How long does it exist? Several decades
Very active volcano with almost continous eruptions. Summit of this spectacular, 2,860 m tall volcano is covered with glaciers and snow.
Vanuatu, Ambrym Island
When the lava lake existed? 1990ies – December 2018
One of the most active volcanoes in the world. In areas which have not been affected by the acid rain from the volcano, grows gorgeous tropical forest. Lava lake here disappeared together with the lava lake in the nearby Mbwelesu Crater.
United States, Hawaii Island
When the lava lake existed? 1823 (or before) – May 2018
This spectacular and comparatively easily available lava lake seemed to be permanent… until it disappeared in 2018. Nevertheless, Kilauea Crater is a very impressive, continuously changing area!
Vanuatu, Ambrym Island
When the lava lake existed? From the 1990ies to December 2018
This spectacular lava lake was well visible from the rim of the crater. From this lake rised constant, up to 30 m high lava fountains. Few places on Earth were that mesmerizing. Lava lake in Mbwelesu Crater disappeared together with the lava lake in the nearby Benbow Crater.
Volcanoes are unquestionably one of the most spectacular and awe-inspiring features of the physical world. Our paradoxical fascination with them stems from their majestic beauty and powerful, sometimes deadly, destructiveness. Notwithstanding the tremendous advances in volcanology since ancient times, some of the mystery surrounding volcanic eruptions remains today. The Encyclopedia of Volcanoes summarizes our present knowledge of volcanoes. It provides a comprehensive source of information on the causes of volcanic eruptions and both the destructive and beneficial effects.
Some 73,000 years ago, the huge dome of Mount Toba, in today’s Sumatra, Indonesia, began to rumble. A deep vibration shook the entire island. Jets of steam and ash emanated from the summit, followed by an explosion louder than any sound heard by Homo sapiens since our species evolved on Earth. The eruption of the Toba supervolcano released the energy of a million tons of explosives. Seven hundred cubic miles of magma spewed outward in an explosion forty times larger than the largest hydrogen bomb and more than a thousand times as powerful as the Krakatau eruption in 1883.
