  • Erta Ale Volcano - Ethiopia, Afar. One of the most active volcanos in the world, with constant lava lake (sometimes two lakes) in the crater, known since 1906. None of the other known lava lakes in the world have such a long lifetime.
  • Mount Cameroon - Cameroon, Southwest. Possibly the oldest still-active volcano in the world which has been active for 30 million years at least. This enormous mountain rises 4 040 m from the ocean and is located over one of the largest known reservoirs of magma.
  • Mount Kilimanjaro, symbol of Tanzania

    Mount Kilimanjaro - Tanzania, Kilimanjaro. Largest free standing volcanic mass in the world, highest mountain in Africa, 5,895 m high. Volcano rises 4,877 m above the surrounding plain. Summit has permanent glacier, which is quickly disappearing. Mount Kilimanjaro includes several unique ecosystems, such as the highest cloud forests in Africa at 4,100 m height and stands of Dendrosenecio plants.
  • Mount Nyiragongo - Congo DR, Nord-Kivu. One of the few volcanos in the world with nearly permanent lava lake in it, often the largest lava lake in the world. Height of the mountain - 3,470 m. Depth of lava lake has reached up to 600 m. Volcano is very active, with frequent eruptions. Eruptions produce very fluid lava of rare type. Speed of lava flows here can reach 100 km/h and the volcano is very steep. When the walls of volcano are fractured, lava flows can become very dangerous, as happened in January 1977 and January 2002.
  • Ngorongoro Crater - Tanzania, Arusha. Largest volcanic caldera in the world, up to 610 m deep and 260 km² large. Area of exceptional concentration of wild animals, with 25,000 large animals living in the crater.
  • Nyamuragira Volcano - Congo DR, Nord-Kivu. The most active volcano in Africa which contains an intermittent lava lake which seems to become more stable and permanent.
  • Ol Doinyo Lengai - Tanzania, Arusha. The only known carbonatite volcano in the world (except for the neighboring Kerimasi volcano). Volcano produces natrocarbonatite lava with nearly unique minerals - nyerereite and gregoryite. Lava flows at very low temperature at 500 - 600 °C. Carbonates react with moisture of atmosphere and quickly turn white, creating unique volcanic landscape. Here in steep cone has been observed formation of new, nearly unique lava cave with enormous stalactites made of fragile natrocarbonatite.
  • Formica Leo crater in Piton de la Fournaise, Réunion

    Piton de la Fournaise - Reunion. One of the most active volcanoes in the world, erupted more than 100 times since 1640. Impressive, deep caldera - Enclos Fouqué. Interesting is smaller crater inside - Formica Leo, resembling sand formations by antlions. Flows of basalt lava sometimes reach the ocean.
  • Suswa Volcano - Kenya, Rift Valley Province. Volcano with unique double crater - it resembles a mountain with deep pressed ring around its summit. The isolated inner summit is covered with dry bush - forest. Fumaroles are observed here. Volcano has more than 30 interesting lava tube obsidian caves.
  • Trou au Natron - Chad, Tibesti. Volcano with grandiose caldera - 8 km wide and 1 km deep, with mostly vertical walls. One the base of caldera there is visually interesting, symmetrical ash cone and crater lake. Dark ash cone is contrasting with nearly white carbonate salts around it.

Antarctica

  • Mount Asphyxia (Mount Curry) - South Sandwich Islands, Zavodovski Island. Volcano which rises 550 m tall. Often emits suffocating fumes, what together with penguin guano creates an unbearable stench.
  • Mount Erebus lava lake - Antarctica, Ross Island. One of the few constant glowing lava lakes in the world.
  • McDonald Islands - Heard and McDonald Islands. Active volcano, at least 230 m high. The interesting feature of this volcano is that over the last decades it has turned two of the McDonald Islands into a single island. Through the eruptions the area and height of the main island increased, connecting it with Flat Island.
  • Mount Michael - South Sandwich Islands, Saunders Island. An active volcano on this small, glacier-covered island. Its 0.7 km wide crater in 2002 - 2006, and, possibly, up to this day contains one of the few active lava lakes in the world.

Asia

Lake water changes color over the time from almost white and azure to emerald green. Lake is sacred, it is located in Aso caldera - one of the largest volcanic calderas in the world, 25 by 18 km large.
  • Patomskiy Crater (Kolpakova Cone) - Russia, Irkutsk Oblast. Unusual crater - 40 m tall and 160 m wide mound/ring of limestone with a smaller mound inside. Most likely it was created by gaseous eruption some centuries ago.
  • Shōwa-shinzan - Japan, Hokkaidō. Volcanic lava dome which rised from the wheat fields in 1944 - 1945. Now the mountain is 398 m high and is smoking.
  • Taal Volcano and Taal Lake - Philippines, Batangas. Taal is active volcano, 400 m high. Unusual feature is the fact that there is a lake on island (Luzon), with a summit of volcano as island in this lake and crater lake in the middle of this volcano with small island in it. Picturesque landscape. Since the 1990s there have been observed several geysers and mud geysers which are not permanent but rather are signalling about increased activity of volcano. In Taal Lake lives the only freshwater sardine in the world (Sardinella tawilis) and the only freshwater seasnake (Hydrophis semperi) and many other endemic species.

Europe

  • Benbow lava lakes, Marum lava lakes and Ambrym volcano acid rain - Vanuatu, Malampa, Ambrym island. In these closely located craters very often are observed nearly permanent, violently boiling lava lakes. Benbow crater is spectacular, very deep hole with vertical walls. Acid rain formed by the gases from craters has burned approximately 100 km² large plain in the jungle of Vanuatu. Here live specially adapted organisms - insects, orchids.
  • Curtis Island Volcano - Kermadec Islands, Curtis Island. This small (500 x 800 m, 137 m high) island represents a summit of active volcano with fumaroles. Crater of this volcano is located approximately 10 m above the sea level. Island is quickly rising - it rised 7 m between 1929 and 1964. Almost every day here are earthquakes.
  • Daikoku Sulphur Cauldron - Northern Mariana Islands. Submarine volcano north from Farallon de Pajaros. A unique pool of liquid sulphur, possibly the only one in world.
  • East Diamante Volcano Black Forest - Northern Mariana Islands. Submarine volcano between Anatahan and Saipan. A group of more than 50 sulphide mineral chimneys, emitting a metal rich, hot solution. The tallest chimneys are up to 9 m tall.
  • Home Reef – Tonga, Vava'u. Ephemeral volcanic island, which after eruptions rises above the sea and then is washed away. Last time such event took place in 2006, when the island became 0.5 by 1.5 km large, with hot crater lakes on it. There are several more such ephemeral islands in Tonga.
  • Kavachi - Solomon Islands, Western Province. Unusual, very active submarine volcano. Since the first sighting in 1939 it has rised above the sea level at least eight times and then eroded back.
  • Eruption of Kīlauea volcano, 1954

    Kīlauea - United States, Hawai'i. One of the most active volcanoes of the world, contains one of the few lava lakes in the world.
  • Kuwae submarine volcano - Vanuatu, Shefa, sea between Epi and Tongoa islands. One of the most active volcanoes in Vanuatu. It is possible that here was a catastrophic eruption in 1452 - 1452 AD. This eruption possibly created the present day sea between Epi and Tongoa. This was the largest eruption in last 10,000 years, leaving serious impact on climate worldwide. Submarine fumaroles from this volcano stain the sea water yellow, there rise bubbles of hydrogen sulfide as well.
  • Mauna Loa - United States, Hawai'i. Volcano with the largest area in the world (of volcanoes above the sea level).
  • Mauna Kea - United States, Hawai'i. One of the highest mountains in the world if measured from its underwater base - 10,203 m high, 4,207 m above the sea level.
  • Molokini crater - United States, Maui. Partially submerged volcanic crater. Some 600 m long crescent shaped summit rises above the water. Exceptional scuba diving site due to calm water, good visibility and exceptional biological diversity.
  • Mount Yasur - Vanuatu, Tafea, Tanna island. One of the most active volcanos in the world, erupting at least for several centuries. Volcano represents impressive, barren cinder cone contrasting with the usual forested landscape of Vanuatu. Often several times in one hour can be observed spectacular explosions of molten lava. Volcano is 361 m high.
  • Pu'u 'Ō'ō - United States, Hawai'i. One of cinder cones of Kīlauea, erupting continuously since January 1983. Longest lived known rift-zone eruption. Continuous lava flows from this cone constantly change the geography of the island.
  • Saleaula Lava Field - Samoa, Gaga'emauga. A lava stream from Mount Matavanu, which buried 5 villages. Especially impressive are the ruins of church, filled with lava. "Virgins Grave" is a burial place of nuns which miraculously was not covered by lava.

  • Arenal Volcano - Costa Rica, Alajuela. 1,670 m high volcano with perfect conical form. One of the most active volcanos in the world, very often offering a beautiful sight of red-glowing lava flowing down its slopes.
  • Concepción volcano on Ometepe - Nicaragua, Rivas. Perfectly symmetrical volcanic cone, rising almost 1.6 km above the lake, thus turning Ometepe island into the highest lake island in the world.
  • Fort Rock - United States, Oregon. Unusual landmark - tuff ring which rises 105 m above the surrounding plain.
  • Kick-'em-Jenny – Grenada, Saint Patrick. Active submarine volcano north from Grenada. This volcano rises some 1,300 m above the sea floor and is just some 180 m below the sea surface. Crater contains fumaroles which emit bubbles of gas.
  • Masaya volcano and its acid rain - Nicaragua, Masaya. Very active and unusual volcano (635 m) with several active craters. One crater contains molten lava, Santiago crater emits large amounts of sulfur dioxide, which 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.
  • Mount Cleveland - United States, Alaska, Aleutian Islands. Near symmetrical stratovolcano, 1 730 m high. Almost constantly active. Nearby from the sea rise several more symmetrical volcanic cones - such as the beautiful cone of Mount Carlisle and Herbert Island.
  • Mount Douglas crater lake - United States, Alaska, Kenai. Approximately 160 m wide, highly acidic crater lake with pH of its water reaching 1.1.
  • Mount Martin - United States, Alaska, Lake and Peninsula. Volcano with very active fumarolic activity. Crater contains acidic lake and thick sulphur deposits.
  • Mount Shishaldin at sunset, Alaska

    Mount Shishaldin - United States, Alaska, Umnak. Most symmetrical cone-shaped glacier clad mountain in the world, 2857 m high. Volcano is continuously active, emitting a plume of steam.
  • Parícutin – Mexico, Michoacán. Newly born volcano which appeared in cornfield in 1943 and grew 336 m tall in one year time, finally achieving height if 424 m in 1952.
  • Poás volcano - Costa Rica, Alajuela. 2,708 m high, very active and unusual volcano. Contains Laguna Caliente - lake of extreme acidity reaching up to 0.0 of pH, filled with acid-sulphate-chloride brine of light green color. Lake is up to 50 m deep, 300 m wide, temperature: 22 - 94 °C. Frequent phreatic eruptions may eject this acid up to 1 kilometre high. Sometimes this effect is considered to be a kind of geyser activity but the mechanism behind this phenomenon is different than in true geysers. Another unique phenomenon linked to this monument is acid clouds of Poás Volcano. Around the Laguna Caliente and for several kilometres down from it all the vegetation is stunted brown and black by the extremely acid clouds coming from this lake. As a result here exists one of the most weird "elfin forests" of the world, often adorned with beautiful flowers.
  • S P Crater - United States, Arizona. Well defined cinder cone with dark lava flow extending from it. This symmetric cone rises 250 m above surroundings.

South America
