Sakurajima, also romanized as Sakurashima or Sakura-jima, is an active composite volcano (stratovolcano) and a former island (now connected to the mainland) of the same name in Kagoshima Prefecture in Kyūshū, Japan.
Sakurajima is a composite mountain. Its summit is split into three peaks, Kitadake (northern peak), Nakadake (central peak) and Minamidake (southern peak) which is active now.
Sakurajima is located in the Aira caldera, formed in an enormous eruption 22,000 years ago. Several hundred cubic kilometres of ash and pumice were ejected, causing the magma chamber underneath the erupting vents to collapse.
1914 eruption was the most powerful in twentieth-century Japan. Lava flows filled the narrow strait between the island and the mainland, turning it into a peninsula.

The 1914 eruption began on January 11. Almost all residents had left the island in the previous days, in response to several large earthquakes that warned them that an eruption was imminent. Initially, the eruption was very explosive, generating eruption columns and pyroclastic flows, but after a very large earthquake on January 13, 1914 which killed 35 people, it became effusive, generating a large lava flow. Lava flows are rare in Japan—the high silica content of the magmas there mean that explosive eruptions are far more common —but the lava flows at Sakurajima continued for months.
Sakurajima’s activity became more prominent in 1955, and the volcano has been erupting almost constantly ever since. The Sakurajima Volcano Observatory was set up in 1960 to monitor these eruptions.
After watching Sakurajima Volcano erupt daily for months on end, we noticed last week (October 11, 2011 a NEW spot erupting smoke/steam on the back side of the mountain… this has now progressed into a full blown large venting — possibly the formation of a new caldera, or a second smaller cone.
After being offline for 2 days… Sakurajima is back on line … we see a large eruption of lava on October 15, 2011, literally covering the entire mountainside… the second plume appears to still be steaming.
Besides the continuous activity of Sakurajima Volcano, UFOs / Orbs are often spotted on the site. The unexplained activities are recorded by the live web cams. Three videos of assumed UFOs/Orbs
Is there an explanation for the UFO sightings above Sakurajima Volcano and what can we expect from this volcano since the eruptions rapidly persist.
