Postcaldera activity has included the production of the Wizard Island cinder cone volcano in Crater Lake. Since the climactic eruption 7,700 years ago, all eruptive activity at Mazama has occurred within the caldera. [81] After the caldera formed, the original crater was widened by avalanches from the walls.

Quilotoa (Spanish pronunciation:) is a water-filled crater lake and the most western volcano in the Ecuadorian Andes.The 3-kilometre (2 mi)-wide 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 ...
Wizard Island was created after Mount Mazama, a large complex volcano, erupted violently approximately 7,700 years ago, forming its caldera which now contains Crater Lake. Following the cataclysmic caldera-forming eruption, which left a hole about 4,000 feet (1,200 m) deep where the mountain had once stood, a series of smaller eruptions over ...
Crater Lake actually started as a mountain, Mount Mazama. A volcanic eruption roughly 7,700 years ago caused the mountain to collapse inward over time, forming a volcanic crater, the park says.
Between June 6 and 9, 1912, the most spectacular Alaskan eruption in recorded history and the 20th century's largest measured volcanic eruption formed a large summit caldera at Katmai volcano. [3] [4] The eruption happened at a vent about 6 mi (10 km) to the west of Mount Katmai (at the Novarupta Volcano). During over 60 hours, the volcano ...
Lake Pinatubo, the crater lake resulting from the 1991 eruption, pictured here in 2008. Activity at the volcano remained low until July 1992 when a new lava dome started growing in the caldera. Volcanologists suspected that further violent eruptions could be possible, and some areas were evacuated. However, the eruption was only minor.
Trou aux Cerfs (also known as Murr's Volcano) is a dormant, crater lake, cinder cone volcano with a well-defined cone and crater. It is 605 m (1,985 ft) high and located in Curepipe , Mauritius . The crater has been alternately described as 300 [ 1 ] and 350 meters in diameter, [ 2 ] and is 80 meters deep.
