Volcano Eruption in Japan on Monday, 07 April, 2014 at 05:25 (05:25 AM) UTC.

Description 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. The first original vent (cone 1, right in the picture) that build the new island and grew to a nice, symmetrical cone, seems to be inactive at present. The other vent is still active and has grown a bit since the previous overflight, with a crater that emits an ash and steam plume, presumably from mild explosive activity caused by infiltrating sea water that becomes in contact with the magma. Bluish gas on the pictures shows areas where active lava flows near their vents. Landsat 8 infrared images from 30 March show that there are active flow fronts all along the eastern coast, while only 2 lobes are active towards the west.

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.
