Cerro Azul is the site of one of the largest explosive eruptions in the 20th centuries. It erupted from the Quizapu vent on April 10-11 1932, producing a Plinian eruption column of 27-30 km (ca. 95,000 ft) height. The eruption formed a 600-700 m wide 150-m-deep crater and blanketed the region with ash. Quizapu is one of Azul's major vents and located on the northern flank of Cerro Azul. It formed in 1846 during the first historical eruption at Cerro Azul, which was accompanied by voluminous dacitic lava flows that traveled both east into the Estero Barroso valley and west into the Río Blanquillo valley. Quizapu was also the site of the massive 1932 eruption. La Resoloma Craters are 3 basaltic-andesite cinder cones on the W flank. They erupted Los Hornitos are cinder cones on the lower SW flank. Note: there are 2 volcanoes with similar names: Volcan Azul in Nicaragua, and Cerro Azul in the Galapagos Islands.

- The Chao lava dome in northern Chile near Calama town is one of the largest known lava domes in the world. It measures 14.5 km in length and 350-400 m in height.
- Chikurachki stratovolcano forms highest peak on Paramushir Island in the northern Kurile island arc just south of Kamchatka Peninsula. It is one of the region's most active volcanoes. The volcano itself is a relatively small cone, compared to other volcanoes of the Kurile Islands, but it is built on top of the high-lying remnants of an older and now extinct predecessor volcano. The dominantlyc basaltic one has steep slopes with little erosion and a shallow summit crater of approximately 450 m in diameter. The upper part of Chikurachki's cone is red, caused by oxidized basaltic-to-andesitic scoria deposits. Eruptions of Chikurachki volcano: There are 2 principal types of eruptions from Chikurachki: 1) frequent strombolian (mildly explosive) eruptions, such as in 1958, 1961, 1964, 1973, 2002, 2003, and 2) (sub-)plinian (extremely violent and dangerous) explosive eruptions such as in 1853 and 1986. The strombolian-type eruptions usually last between several days to few weeks, and produce ejections of incandescent lava reaching 100-500 m height above the crater, but can occasionally produce ash plumes of up to 3 km height. Many eruptions from Chikurachki are accompanied by lava flows. Some have reached the sea and form capes on the NW coast, and there are young lava flows on the upper eastern flank.Basaltic plinian eruptions are a globally rare phenomenon, but common at Chikurachki volcano, and it is estimated that they have occurred every 100–200 years. Such eruptions - similar to the Icelandic Grimsvötn's eruption in June 2011 - are capable of producing tall ash plumes reaching 10-20 km and pose a significant hazard to aviation in an area densely populated by flight routes from N-America to Asia. -> See whole entry
- Volcán Chiliques is a stratovolcano in northern Chile immediately south of Laguna Lejía. The volcano consists of a symmetrical cone rising 1000 m from the surrounding terrain and contains a 500 m wide crater. Several young lava flows are seen on its flanks and some might be younger than 10,000 years. The largest flow extends 5 km to the NW, but older flows have reached 10 km distance on the north flank towards Laguna Lejía. In April 2002, first signs of a possible reawakening of the volcano were detected as new hot spots inside the crater.
- Chimborazo volcano is Ecuador's highest active volcano and the highest in the Northern Andean Volcanic Zone. The massive, ice-capped stratovolcano lies at the southwest end of the main Ecuadorian volcanic arc, the so-called "Avenida de los Volcanes" ("Avenue of Volcanoes") and is located ca. 150 km SSW of Quito and 28 km NW of the town of Riobamba. Chimborazo had been thought to be extinct, but new studies have shown that it still is an active volcano. Although there are no historical eruptions, Chimborazo erupted at least 7 times during the past 10,000 years. These eruptions produced pyroclastic surges that reached down to 3800 m elevation. The average time interval between single eruptions is about 1000 years and the last eruption occurred about 1400 years ago, which means that statistically, it is due for another one. Due to its great height and its geologic history of explosive eruptions, and closeness to populated areas in Ambato and Riobamba basins, it should be considered a dangerous volcano. -> See whole entry

Clear Lake (Volcano)
- Clear Lake volcanic field lies in the northern Coast Ranges, California, ca. 135 km north of San Francisco. The volcanic field consists of lava dome complexes, cinder cones, and maars of basaltic-to-rhyolitic composition. Mount Konocti, a dacitic lava dome on the south shore of Clear Lake, is the largest volcanic feature. The area has intense gethermal activity, caused by a large, still hot silicic magma chamber about 14 km wide and 7 km beneath the surface. It provides the heat source for the Geysers, the world's largest producing geothermal field on the SW side of the volcanic field. Its geothermal power plants can generate approximately 2000 megawatts, enough to power two cities the size of San Francisco. The latest volcanic activity happened about 10,000 years ago and formed maars and cinder cones along the shores of Clear Lake, the larges natural freshwater lake in California. Volcanism around Clear Lake is related to the complex San Andreas transform fault system. -> See whole entry

Comondu-La Purisima (Volcano)
- Comondú-La Purísima volcano is a volcanic field of about 9000 sq km in southern Baja California, west of the Sierra de la Giganta. Volcanic activity of La Purısima dates back about 10 million years ago, but might have continued into the Holocene (i.e. less than 10,000 years ago), as some of the cinder cones and blocky lava flows, in the area between Comondú and the La Purísima river, have preserved a very fresh morphology. -> See whole entry
- Concepción volcano is a steep symmetrical stratovolcano with a perfect shape and one of the most active volcanoes of Nicaragua. During the past 100 years, it has been in a near-constant state of small to medium ash explosions at irregular intervals. Together with its neighbor Madera volcano Concepción forms the NW half of the dumbbell-shaped island of Ometepe in Lake Nicaragua. Both volcanoes are connected by a narrow isthmus. Frequent explosive eruptions during the past decades have increased the height of its summit significantly (more than 100 m) and outdated the existing topographic maps. Because of the frequent ash eruptions, the upper half of the summit cone lacks vegetation. The basaltic-to-dacitic Concepción volcano contains a steep-walled 250 m summit crater with a higher western rim. Flank vents are aligned on N-S-trending fractures and contain chains of spatter cones, cinder cones, lava domes, and maars on the NW, NE, SE, and southern sides. Some of these vents are found down to Lake Nicaragua. -> See whole entry

- Mount Ediziza in NW British Columbia, Canada is a large, complex stratovolcano about 1 million years old forming the most recently active of a group of overlapping basaltic shields, lava domes, flows, and central stratovolcanoes. Mount Edziza contains a 2-km-wide, ice-filled summit caldera with a central summit crater and several flank vents. The volcano's lavas range from basalt to rhyolite. Frequent volcanic activity of the complex has been going on for about 8 million years, but the last eruptions occurred only about 1000 years ago. After the Level Mountain Range to the north, Edziza is Canada's second largest young volcano. Volcanic activity of the Edziza complex is caused by extension structures in the underlying basement and the volcano lies along a zone of north-south normal faults east of the Coast Crystalline Complex. Active or recently active warm springs are found in several areas along the western flank of the volcanic plateau, including Elwyn springs (36°C), Taweh springs (46°C), and inactive springs near Mess Lake. All 3 hydrothermal areas are near the youngest lava fields on the plateau and are probably associated with the most recent volcanic activity at Mount Edziza. The vast plateau has also been an important cultural resource. The Tahltan people, who now live largely near Telegraph Creek, British Columbia, used volcanic glass (obsidian) from Mount Edziza to make tools and for trading material. More recently, most of the plateau has been made into a provincial park to preserve the volcanic and culture treasures unique to the northern British Columbia area. -> See whole entry
