Lava domes are common features on volcanoes around the world. Lava domes are known to exist on plate margins as well as in intra-arc hotspots, and on heights above 6000 m and in the sea floor. [ 1 ] Individual lava domes and volcanoes featuring lava domes are listed below.
The world's largest known dacite flow is the Chao dacite dome complex, a huge coulée flow-dome between two volcanoes in northern Chile. This flow is over 14 kilometres (8.7 mi) long, has obvious flow features like pressure ridges, and a flow front 400 metres (1,300 ft) tall (the dark scalloped line at lower left). [ 15 ]
Mount Gareloi, or Gareloi Volcano, is a stratovolcano in the Aleutian Islands of Alaska, United States, about 1,259 miles (2,026 km) from Anchorage. Gareloi is located on Gareloi Island , and comprises most of its land mass.

Augustine Volcano (Sugpiaq: Utakineq; [3] Dena'ina: Chu Nula) is a stratovolcano in Alaska consisting of a central complex of summit lava domes and flows surrounded by an apron of pyroclastic, lahar, avalanche, and ash deposits. The volcano is frequently active, with major eruptions recorded in 1883, 1935, 1963–64, 1976, 1986, and 2006.
Red Island (or Red Hill) is a lava dome volcano in the Salton Trough, and part of the Salton Buttes, the only active volcanoes in Southern California. It is located in Imperial County, California. It contains two lava domes, Prospect Dome and Alamo Dome. [1] The domes have been dormant for 2,000 to 8,000 years.
Its relatively high summit is a consequence of its location atop a high ridge, but its volcanic portion extends only 1,600–3,200 feet (500–1,000 m) above the underlying ridge. [13] Another Cascade Arc volcano with similar geomorphology is the Mount Meager massif in southwestern British Columbia , Canada, which is situated on a 1,300 ft (400 ...
The Mazama vicinity formed gradually, its earliest deposits consisting of dacite from up to 1.28 million years ago. Between 725,000 and 500,000 years ago, rhyodacite was erupted, eventually forming a lava dome field with a volume of 4.8 cubic miles (20 km 3) and dimensions of 9.9 by 14.9 miles (16 by 24 km). This featured up to 40 rhyodacitic ...
