Holocene calderas

Krakatoa (), also transcribed (), is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa archipelago) comprising four islands. Two of them are known as Lang and Verlaten; another, Rakata, is the only remnant of an island, also called Krakatoa, mostly destroyed by an eruption in 1883 which created the caldera.

Novarupta is a volcano located on the Alaska Peninsula on a slope of Trident Volcano in Katmai National Park and Preserve, about southwest of Anchorage. Novarupta was formed in 1912, during the largest volcanic eruption of the 20th century, in which it released 30 times the volume of magma of the 1980 eruption of Mount St. Helens.

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.

Uzon () is a 9 by 12 km volcanic caldera located in the eastern part of Kamchatka Peninsula, Russia. Together with the Geyzernaya caldera it hosts the largest geothermal field in the Kamchatka Peninsula. The calderas were formed in the mid-Pleistocene in several large eruptions that deposited 20–25 km3 of ignimbrite over a wide area. Lake Dalny fills a Holocene maar in the northeast of Uzon Caldera.

thumb|Caldera and bay of Yankicha Ushishir (; Japanese: 宇志知島; Ushishiru-tō; Ainu: ウシシㇼ, lit. "Land of the bay") is a collective name for two uninhabited volcanic islands and several reefs, all being parts of an eponymous partially submerged volcano, located in the centre of the Kuril Islands chain in the Sea of Okhotsk in the northwest Pacific Ocean. Its name is derived from the Ainu language for "hot spring".

Atacazo is a volcano of the Western Cordillera located 25 kilometers southwest of Quito, Ecuador. Atacazo is a stratovolcano formed by the action of a Late-Pleistocene to Holocene caldera. The last eruption of the Atacazo was nearly 2300 years ago.

Ksudach () (also known as Vonyuchy Khrebet Volcano) is a stratovolcano in southern Kamchatka, Russia. The last eruption of Ksudach was in March 1907, on or around 28 March, which was one of the largest ever recorded in Kamchatka with a Volcanic Explosivity Index of 5. The summit area comprises overlapping calderas. Two lakes, Bolshoe and Kraternoe, are located within calderas at the summit of Ksudach. These lakes, along with hot springs and the surrounding wilderness, make the Ksudach Volcano region a popular trekking destination. In the event of renewed volcanic activity, its remote location

Ceboruco is a dacitic stratovolcano located in Nayarit, Mexico, northwest of the Trans-Mexican Volcanic Belt. The largest eruption, the Jala Plinian eruption, was around 930 AD ±200, VEI 6, releasing of tephra. The most recent and best documented eruption from Ceboruco lasted from 1870–1875, with fumarole activity lasting well into the 20th century. The mountain features one large caldera, created during the Jala eruption, with a smaller crater nested inside that formed when the Dos Equis lava dome collapsed during the Coapales eruption around 1100 AD. Within both of these craters,

Calabozos is a Holocene caldera in central Chile's Maule Region (7th Region). Part of the Chilean Andes' volcanic segment, it is considered a member of the Southern Volcanic Zone (SVZ), one of the three distinct volcanic belts of South America. This most active section of the Andes runs along central Chile's western edge, and includes more than 70 of Chile's stratovolcanoes and volcanic fields. Calabozos lies in an extremely remote area of poorly glaciated mountains.

Vulsini, also known as Volsini volcano, Vulsini Volcanic District, Vulsini Volcanic Complex and the Vulsinian District, is a circular region of intrusive igneous rock in Lazio, Italy, about to the north northwest of Rome, containing a cluster of calderas known to have been active in recent geologic times. The Vulsinian region is one of dozens of intrusive circular regions, most smaller than the Vulsinian, arranged in a band from Campania through Lazio, called the Roman Comagmatic Province.
