Indecision Creek
A stream with waterfalls that flows down from Mount Chiginagak volcano. Stream is very acidic, with pH of 1.2, its water has a sulfuric odor.

Volcano with a very active fumarolic activity. The crater contains an intermittent acidic lake and thick sulfur deposits.

Approximately 160 m wide, highly acidic crater lake with pH of its water reaching 1.1.
Devil Mountain Lakes

Possibly the largest maar in the world – two joined round lakes formed by a volcanic eruption some 21 000 years ago. The diameter of lakes reaches 8 km. Several more maar lakes are nearby.

Wondermondo 🢖 Lists and articles 🢖 Lava lakes of the world Publication Lava lakes of the world In short The number of lava lakes in the world changes. Thus, over 2018-2019 disappeared three lava lakes that previously existed for decades. As a result, in October 2019 we have seven existing lava lakes on Earth. Three more existed for a […]
Nabro Volcano

Impressive, 2,218 m tall (before the eruption) stratovolcano that was considered to be extinct until it erupted unexpectedly on 13 June 2011. There might be a lava lake in the northern caldera of the volcano.
Mount Belinda

One of the few active volcanoes under the jurisdiction of the United Kingdom. This volcano rises 1,370 m above sea level. The summit of the volcano rises from a glacier that covers almost the whole island. The eruption in 2002 – 2009 created a 90 m wide, subglacial river from the molten ice, which reached the sea, creating a steam plume. MODIS imagery around 2004 indicated that it is possible that in the crater of the volcano is a persistent lava lake. Most likely now it does not exist as the crater is covered with a thick layer of snow.
Mawson Peak of Big Ben

An active volcano, last eruption took place in 2008, but there have been many more eruptions over the last decades, mostly fixed only by satellites from space. The tallest part – Mawson Peak – is the highest mountain in the territory of Australia (2,745 m). Satellite data shows that there might be located lava lake with a diameter of 100 – 150 m.
Villarrica volcano

Large, 2,860 m tall volcano that has an intermittent lava lake in its 50 m wide craters. Summit of the volcano is permanently covered with snow and glaciers.
Masaya volcano

Very active and unusual volcano (635 m) with several active craters. Santiago crater emits large amounts of sulfur dioxide that created acid rain and eliminated vegetation around the volcano. Masaya crater contains intermittent lava lakes – in 1670 in Nindiri crater it was up to 1 km large, by far the largest known lava lake.
