Copahue () is a stratovolcano in the Andes on the border of Bío Bío Region, Chile and Neuquén Province, Argentina. There are nine volcanic craters along a line, the easternmost of which is historically the most active, and contains a 300 m (1000 ft) wide crater lake with a pH ranging between 0.18 and 0.30. Eruptions from this crater lake have ejected pyroclastic rocks and chilled liquid sulfur fragments. Although the lake emptied during the 2000 eruption, it later returned to its previous levels. Copahue means "sulphur waters" in Mapuche.

The Kelud (, sometimes spelled as Klut, Cloot, Kloet, Kloete, Keloed or Kelut) is a mountain stratovolcano located in Kediri, East Java, Indonesia. Like many Indonesian volcanoes and others on the Pacific Ring of Fire, Kelud is known for large explosive eruptions throughout its history. More than 30 eruptions have occurred since 1000 AD. In 2007, an effusive explosion filled the crater with a lava dome. It last erupted on 13 February 2014, destroying the lava dome and ejecting boulders, stones and ashes up to West Java about from Mount Kelud. The crater filled with water during the rainy seaso

Kanlaon, also known as Mount Kanlaon and Kanlaon Volcano (; ; ), is an active andesitic stratovolcano and the highest mountain on the island of Negros in the Philippines, as well as the highest peak in the Visayas, with an elevation of above sea level. Mount Kanlaon ranks as the 42nd-highest peak of an island in the world.

Quilotoa () is a water-filled crater lake and the most western volcano in the Ecuadorian Andes. The caldera was formed by the collapse of this dacite volcano following a catastrophic VEI-6 eruption about 800 years ago, which produced pyroclastic flows and lahars that reached the Pacific Ocean, and spread an airborne deposit of volcanic ash throughout the northern Andes. This last eruption followed a dormancy period of 14,000 years and is known as the 1280 Plinian eruption. The fourth (of seven) eruptive phase was phreatomagmatic, indicating that a crater lake was already present at that time.
