Zao volcano is the most active volcano of northern Honshu and consists of a group of stratovolcanoes forming the crest of the divide between the Pacific Ocean and the Japan Sea.
The older parts of the complex are Ryuzan volcano in the west and Byobu and Fubo volcanoes forming the southern group. Zao volcano proper (Chuo-Zao) is the youngest edifice and forms the central part of the group. One of its youngest summit lava domes is Goshiki-dake, which contains the active Okama crater, the source of most of the frequent historical eruptions recorded since the 8th century AD.
Okama crater contains a colorful, strongly acidic crater lake (pH 1.3). -> See whole entry
Zapatera volcano is a low shield volcano forming a 7 x 10 km wide densely forested island on the western part of Lake Nicaragua. The island is located opposite Mombacho volcano and separated by a narrow strait from the mainland.
Zapatera volcano is believed to be still active, but the age of its last activity is unknown.
Zapatera island contains some of the most important archaeological sites in Nicaragua and is part of Zapatera Archipelago National Park, one of 78 protected areas of Nicaragua. -> See whole entry
Zavaritzki (Zavaritzky) volcano is a large caldera volcano in central Simushir Island, Kuriles. It is a complex of 3 nested calderas with a central lake (Lake Biryuzovoe). 2 eruptions have occurred at Zavaritzki during the 20th century: a recent lava dome was formed between 1916-1931 and created a small island in the northern part of the lake. The second eruption in 1957 formed a new, 350 m wide and 40 m high lava dome also in the northern part of the lake, which decreased a lot in size. The lava dome extrusion was preceded by explosions.
Note: A volcano with the same name is located in Kamchatka. -> See whole entry
Zitácuaro-Valle de Bravo volcano is a volcanic field in the central part of the Mexican Volcanic Belt 80 km SW of Mexico City. It consists of the Zitácuaro complex which formed above the giant, 30 km wide Las Tres Chicas caldera near city of Heroica de Zitácuaro, and the Valle de Bravo field to the south.
The field contains andesitic lava shields, lava domes, and more than 100 cinder cones. The last activity was west of the Valle de Bravo lake. -> See whole entry
Zukur (Zugar) volcano forms the northernmost large island of the Zukur-Hanish island group in the southern Red Sea between Eritrea and Yemen.
It consists of young basaltic pahoehoe lava flows and cinder cones, but there are no known historic eruptions.
Zukur and the other islands of Greater Hanish archipelago in the Red Sea were disputed with fighting between Eritrea and Yemen in December 1995. In 1998 the Permanent Court of Arbitration determined that the most of archipelago, including Zukur Island, belonged to Yemen. -> See whole entry
The Zuni-Bandera volcanic field in New Mexico, is an elongated, 90 km long and 1-35 km wide arrea of 2460 km2 along the Jemez lineament west of the Rio Grande Rift.
The field contains cinder cones and extensive lava flows with various types of basalt lava. The youngest lava flow, the McCartys flow, traveled 60 km to the NE, fed by lava tubes up to 29 km long. Its activity is also found in Indian legends, which is why it was believed to be only 1000 years old, but radiocarbon dating suggests an older age, about 3000 years ago. -> See whole entry
