The Irazú Crater Fumaroles are volcanic gas vents located within the summit crater of Irazú, the highest active volcano in Costa Rica. This stratovolcano is historically significant for its major eruption that began on March 19, 1963, coinciding with the arrival of US President John F. Kennedy for a...

Aso Nakadake crater fumaroles are volcanic gas vents within Mount Aso's active central cone in Kumamoto Prefecture, Japan. Mount Aso is situated within one of the world's largest volcanic calderas, and Nakadake is its only currently active peak. The fumaroles release sulfur dioxide and steam, and vo...

Kawah Domas is a secondary volcanic crater situated on the slopes of Mount Tangkuban Perahu in West Java, Indonesia. Unlike the main crater, it can only be accessed via a guided hike through the surrounding forest. The site is characterized by active geothermal features, including boiling mud pools,...

Maly Semyachik is a volcanic massif on the Kamchatka Peninsula in far eastern Russia. The volcano contains a crater lake notable for its extremely acidic waters, with some of the lowest pH levels recorded in any natural lake. Fumarolic fields around the crater continuously emit sulfurous gases, cont...

The Martin Volcano Fumaroles are a collection of vigorous, persistent gas vents located at the summit of Mount Martin, a stratovolcano in Alaska's Katmai National Park. Unlike many volcanoes that vent through craters, Mount Martin's activity is concentrated entirely through these fumarolic openings,...

The Nakadake fumaroles are volcanic gas vents in the active central crater area of Mount Aso on Kyushu, Japan. They release steam and gases containing sulfur compounds, producing visible plumes, mineral deposits, and a strong sulfurous odor around the crater. Because Nakadake remains active, access...

The Lascar crater fumaroles are vents that discharge hot gases and steam from the summit region of Lascar, an active stratovolcano in the Andes of northern Chile. Their activity reflects the volcano's persistent hydrothermal and magmatic systems and can vary with changes inside the volcanic conduit....
