Sukaria is a poorly known caldera in central Flores Island, NE of Iya volcano. The caldera measures 8 km in diameter and has 750-m-high northern walls, rising above the village of Sukaria, which lies in the center of the caldera.
The southern caldera walls are irregular. Fumaroles and small geysers occur on the western flank.
Sumaco is an active stratovolcano east of Antisana, ca. 100 km east of Quito. It is an isolated mountain about 50 km east of the main volcanic range and rises 2800 m above the western Amazon basin. The volcano contains a 300 x 400 m wide summit crater with a central cone inside. There are 3 reports of eruptions in historic times, but only one eruption around 1895 is believed to actually have taken place. -> Voir la description complète
The large Sumbing volcano in Central Java west of Merapi dominates the landscape between Yogyakarta and the Dieng plateau. It is not certain wether the volcano has erupted in historic times, but it is considered one of Indonesia's active volcanoes. The summit of Sumbing contains an 800 m wide crater breached to NE where a geologically young lava dome was built feeding a lava flow down to 2400 m elevation.
Note: another volcano called Sumbing is found on Sumatra. -> Voir la description complète
Sumiyoshi-ike volcano refers to 2 maars 2 km apart located in the coastal lowland north of the Aira caldera: Sumiyoshi-ike (500 m diameter) and Yonemaru (1.2 km).
The maars erupted when sea level was rising about 8,000 years ago (Sumiyoshi-ike) and 6500 years ago (Yonemaru). The larger of the two, Yonemaru, produced pyroclastic surges that traveled 4 km from the crater.
Sunset Crater in northern Arizona is one of the youngest volcanoes in the USA. It is named for its brilliantly colored scoria deposits on the cone and only one of more than 550 vents of the vast San Francisco volcanic field.
The last eruption took place sometime between about 1080 and 1150 AD.
In the late 1920s, a Hollywood filmmaker planned to use Sunset Crater as movie set and use dynamite to simulate an eruption, but local resistance stopped these plans. -> Voir la description complète
Suwanose-jima (諏訪之瀬島) volcano is Japan's and one of the world's most active volcanoes. It has been in a state of near-continuous strombolian-type eruption since 1949.
The volcano forms the 8 km long spindle-shaped island of the same name in northern Ryuku Islands, Japan. The remote island is home to about 50 residents only.
Suwanose-jima consists of an andesitic stratovolcano with 2 historically active summit craters. Intermittent to continuous strombolian activity began from On-take (Otake), the NE summit crater, in 1949 and has been going on since. After 1996, occasional periods of inactivity have become more frequent. -> Voir la description complète
