Wai Sano (Volcano)
- Wai Sano is a 3.5x2.5 km wide caldera at the western end of Flores Island. It contains a crater lake 260 m below the highest peak of the rim, Mt Umpu Rua peak, and the SE caldera wall is truncated by the slopes of 1632-m-high Gunung Cerak. Although no historic activity is known from Wai Sano, it is believed to have erupted in the past 10,000 years. Two mildy active fumarole areas are located on SE shore of the lake.
- Waiowa volcano (also known as Goropu) is an isolated cinder cone on the mainland of New Guinea 19 km inland from Collingwood Bay in Oro Province. The cone formed in 1943-44 through a series of explosive eruptions in an area without previous volcanic activity. -> See whole entry
- Walo volcano is not actually a volcano, but a geothermal field 5.5 km from Walo village, Bangula Bay on the north coast of New Britain. There are no exposed volcanic rocks, but it contains fumaraoles and hot springs. The Walo thermal area is connected to the nearby Sulu Range volcanoes (Karai volcano). The Smithsonian Institution counts Walo as a subfeature of the Sulu Range volcano. The Walo fumaroles have been used by locals for cooking food.
Wapi Lava Field (Volcano)
- The Wapi lava field, SE of the Craters of the Moon, Idaho, is a low shield volcano that formed during an eruption about 2250 years ago, which produced about 6 cubic km of fluid pahoehoe lava flows. It covers about 325 km2, and consists of a low shield volcano, which partly overlaps the nearby Craters of the Moon lavas. -> See whole entry
- Washiba-Kumonotaira volcano in the Northern Japan Alps is a group of small shield volcanoes and possible lava domes. The volcanoes are located in a remote part of the Chubu Sangaku National Park. The last activity was from Washiba-ike volcano less than 12,000 years ago. -> See whole entry
- Wayang-Windu is a large old lava dome with two peaks located immediately west of Kamojang volcano about 40 km S of Bandung. -> See whole entry
Wells Gray-Clearwater (Volcano)
- The Wells Gray-Clearwater volcanic field is located in the Quesnel Highland of east-central British Columbia, Canada. The volcanoes are basaltic cinder cones and their lava flows. The latest eruption took place from Kostal cone about 400 years ago, thus being one of the most recent volcanic eruptions in Canda. -> See whole entry
West Crater (Volcano)
- West Crater volcano is a small andesitic lava dome with lava flows in southern Washington, belonging to a volcanic field extending from Marble Mountain, north of Swift Reservoir, to south of Trout Creek Hill. The field consists mainly of small basaltic and basaltic andesite cinder cones and small shield volcanoes, oriented along a NW-SE zone SE of Mount St. Helens. The most recent activity occurred about 8,000 years ago and formed the West Crater lava dome, a small cone at Hackamore Creek, and a phreatic crater at the summit of Bare Mountain. The older, basaltic Trout Creek Hill shield volcano erupted a lava flow about 340,000 years ago that traveled 20 km SE and temporarily dammed the Columbia River.
- Whangarei volcano (named after the nearby town of Whangarei) is a group of cinder cones and lava flows. Their age is not well known, and could be as between less than 10,000 and up to about 30,000 years ago. -> See whole entry
White Island (Volcano)
- White Island in the Bay of Plenty ca. 50 km off the North Island's east coast is one of New Zealands most active volcanoes, well known for its spectacular crater with strong hydrothermal activity and sulphur deposits. It is part of the active Taupo volcanic zone and last erupted in 2001 (phreatic explosion). -> See whole entry
- Wilis volcano in the eastern end of Central Java is an isolated volcano with no known historic eruption, although there is a report of an eruption in 1641 AD, but most likely this was an eruption from nearby Kelut volcano. Increased fumarolic activity was reported in 1885. -> See whole entry
- Wudalianchi volcano is one of the youngest volcanic fields on the mainland of Asia. It covers an area of about 500 sq km located at the junction between Xiaohinggan Mountains and Song-Nen depression in NE China. The last eruption was in 1719-1721 and erupted about 1 cu km of mostly pahoehoe lava. The volcano's name Wudalianchi means "Five Connected Pools" because of 5 scenic lava-dammed lakes. The area has been declared a UNESCO World Heritage Location. The volcanic field contains 14 steep sided cinder cones surrounded by lava flows. -> See whole entry
- Wurlali volcano (also called Damar, Daam, Dammer) on Damar Island, Indonesia, 375 km NE of Dili, East Timor, is an andestici stratovolcano and the SW-most historically active volcano in the Banda arc. It has a 5 km diameter caldera and 2 craters at the active northern end of the caldera. Hot springs occur southwest of the volcano near the beach. Fumaroles are present on the south flank and at the summit vents, where large sulphur deposits are found and being exploited. In places, liquid sulfur can be observed boiling in some of the vents.
