How old is the currently active shield volcano located in the Kaʻ ū Desert?
Kīlauea Kīlauea ( , ; ] ) is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻ i. Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago. It is the second youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa, Kīlauea was once thought to be a satellite of its much larger neighbor. Structurally, Kīlauea has a large, fairly recently formed caldera at its summit and two active rift zones, one extending 125 km east and the other 35 km west, as an active fault of unknown depth moving vertically an average of 2 to per year.
Albuquerque volcanic field Albuquerque volcanic field is a monogenetic volcanic field in the Albuquerque Basin in New Mexico, United States. The Albuquerque volcanic field is made of monogenetic volcanoes that produced lava flows, cinder cones, and spatter cones. It is located about 11 km west-northwest of the city of Albuquerque, and is contained within the borders of Petroglyph National Monument. The oldest lava flows cover about 60 square km. The cones are aligned and possibly formed above two roughly north-south trending fissures. J cone (also called Vulcan) is the highest feature. Its base is made of cinder, but the crater contains a lava dome that was cut by an explosive eruption. The Albuquerque volcanic field was active from 170,000 to 70,000 years ago.
