Exlosion at Nakadake volcano (Aso volcano) this morning
Ash plume from Sakurajima this morning
Glow from Calbuco this morning
Aso (Kyushu): Mild to moderate strombolian explosions from the Nakadake crater have become continuous.
Ash emission from Calbuco this evening
Sakurajima (Kyushu, Japan): (25 Apr) Strong vulcanian explosions have been occurring at the volcano, which remains in a state of elevated activity.
During the past 48 hours, at least 17 explosions with ash plumes up to 16,000 ft (5 km) altitude occurred. This approaches the record levels of activity observed during the summer 2013.
Suwanose-jima (Ryukyu Islands): (25 Apr) Several ash plumes were reported by VAAC Tokyo during the past days.
The volcano is having intermittent moderate strombolian type eruptions from the On-take crater.
Ngauruhoe (North Island): (24 Apr) The alert level was lowered back to the lowest level green, after signs of unrest at the volcano gradually had declined during the past weeks.

Calbuco (Southern Chile and Argentina): (25 Apr) Mild to moderate emissions of ash and incandescent material (probably as strombolian explosions) continue at the summit vent(s). A small ash plume rises approx. 1 km and is currently drifting east.
Alert level remains red. A new intensification of activity cannot be ruled out as it is not known how much of eruptible magma in the volcano's storage system has been evacuated during the strong eruptions on 22-23 April.
Starting from 23:30 local time last night (23 April), activity at the volcano has again increased. The volcano started to produce more or less continuous small to moderate ash emissions, that have been reaching up to 2 km height and drifted mainly northeast.
This increase in activity has also been accompanied by volcanic tremor in the seismic signals, Sernageomin reported.
