Ubinas (Volcano)

Uinkaret (Volcano)

The Uinkaret volcanic field is located at the north rim of the Grand Canyon in Arizona. It contains cinder cones that have produced lava flows that repeatedly cascaded into the Grand Canyon, forming temporary lava dams up to 200 m high. In one of these lava flows, known as the Little Springs flow, pottery sherds were found that date to between 1050 and 1200 AD giving the age of the lava flow.

Ula (Volcano)

The massive Gunung Awu stratovolcano occupies the northern end of Great Sangihe Island, the largest of the Sangihe arc. Deep valleys that form passageways for lahars dissect the flanks of the 1320-m-high volcano, which was constructed within a 4.5-km-wide caldera.

Una Una (Volcano)

Una Una (also known as Colo) is an isolated volcano in the Gulf of Tomni, offshore central Sulawesi. It is the site of sulfur extraction.

Ungariana (Volcano)

Ungaran volcano is a probably extinct volcano south of Semarang city at the N coast of Java. Highly eroded, the mountain is the remnant of a stratovolcano that underwent repeated flank collapse. At present, there are only fumaroles and warm springs located on the volcano's flanks as signs of activity.
