Cerro Azul stratovolcano in Central Chile is located at the southern end of the Descabezado Grande-Cerro Azul group of volcanoes. Its steep summit cone contains a 500 m wide crater.
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.

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. -> Voir la description complète
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. -> Voir la description complète
