The island remains active and continues to grow as lava flows add new land to it. The Japanese Coast Guard made another survey flight on 26 August and observed ongoing effusive and explosive activity in the main crater. ...more [read all]

The currently fastest growing island of the world remains active, with both effusive (lava flows enlarging the island) and explosive activity (strombolian and phreatomagmatic = water-magma explosions). ...more

An explosive event occurred last night at the growing island volcano. VAAC Tokyo reported an ash plume at 10,000 ft (3 km) altitude drifting to the northeast.

Eruptions continue to add land to the remote island volcano. Recent pictures by the Japanese Coast guard on 11 and 13 June show steaming along the shoreline, indicating active lava flow fronts, possibly tube-fed since no surface incandescence was visible. ...more [read all]

The eruption on the remote island continues. The most recent overflight pictures by the Japanese Coast Guard show two active vents, one with a small lava-filled vent likely producing strombolian explosions, the other emitting a steam and gas plume. ...more

A possible explosive eruption occurred this morning; VAAC detected an ash plume at estimated 7,000 ft (2.1 km) altitude drifting east from the volcano. This could have been caused by a stronger phreato-magmatic explosion (sea water coming in contact with magma).

The ongoing eruption continues to add new land to the island with what seems a relatively steady effusion of lava flows. A new overflight by the Japanese Coast Guard shows that at least the second vent that appeared in late January is still active, feeding lava flows that continue to spread and currently have active fronts all along the eastern coast. ...more [read all]

The island continues to grow as lava flows slowly spread into several directions. This is shown nicely by the latest aerial survey pictures the Japanese Coast guard took on 28 Feb. The most active flow fronts are currently at the southern shore while advance on the northern and eastern margins of the flow field has slowed down. ...more [read all]

The island continues to grow by progressing lava flows into several directions, as the latest images by the Japanese Coast Guard from 16 Feb show. Its highest peak, formed by the western of the 2 active vents, was measured at 66 m, i.e. it now reached almost twice the height of the peak of the old island. The new addition has more than doubled the size of the island so far. ...more [read all]
