Ubehebe Crater in Springtime. Geologists call the resulting large steam explosions hydrovolcanic or phreatic eruption and the pits created are known as maars.Ubehebe was the last and largest in a series of similar eruptions in the immediate area (its eruption exceeded the tensile strength of the bedrock by 10 times).
The Ubehebe Craters are a volcanic field in the northern Death Valley of California, consisting of 14–16 craters in a 3-square-kilometre (1.2 sq mi) area. The largest of the craters is the 800 metres (2,600 ft) wide and 235 metres (771 ft) deep Ubehebe Crater. Many of the craters, though, are partially buried and thus hardly recognizable.

Mount Shasta (/ ˈʃæstə / SHASS-tə; Shasta: Waka-nunee-Tuki-wuki; [5] Karuk: Úytaahkoo) [6] is a potentially active [7] volcano at the southern end of the Cascade Range in Siskiyou County, California. At an elevation of 14,179 ft (4,322 m), it is the second-highest peak in the Cascades and the fifth-highest in the state.
Mount Nyiragongo (/ ˌnɪərəˈɡɒŋɡoʊ, - ˈɡɔːŋ -/ neer-ə-GONG-go) is an active stratovolcano with an elevation of 3,470 m (11,385 ft) [1] in the Virunga Mountains associated with the Albertine Rift.

A central feature of Jeju is Hallasan, the tallest mountain in South Korea and a dormant volcano, which rises 1,950 meters above sea level. The main volcano includes 360 satellite volcanoes. Volcanic activity on Jeju began approximately in the Cretaceous and lasted until the early Tertiary period. The most recent eruptions are estimated to be ...
The Toba eruption (sometimes called the Toba supereruption or the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago during the Late Pleistocene [2] at the site of present-day Lake Toba in Sumatra, Indonesia. It was the last in a series of at least four caldera -forming eruptions at this location, with the ...
Mount Sinabung is a Pleistocene-to-Holocene stratovolcano. [11] It is located in a relatively cool area on a fertile plateau with mountains bounding the north. [12] The summit crater of the volcano has a complex, longer form due to vents migrating on the N-S line. [11]
