Volcanos

Global Volcanic Activity

Shiveluch (Kamchatka): An explosion occurred at the volcano this morning (Kamchatka time). An ash plume rose to approx. 20,000 ft (6 km) altitude (VAAC Tokyo).

Ubinas (Peru): Ash emissions and small explosions originating at the new lava dome in the crater seem to increase in frequency. The resulting ash plumes have all been relatively small (so far).

Nishino-shima (Volcano Islands): 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.
