Dukono (Halmahera): A volcanic ash plume extending 60 km west and at estimated 11,000 ft (3.3 km) altitude was spotted by VAAC Darwin this morning.
Kavachi (Solomon Islands): It is likely that some volcanic activity has continued intermittently at the undersea volcano after a discolored water plume was first spotted on 29 January this year.
Although no further signs of activity were visible on clear days after the first sightings, satellite images from 21 March and 8 May, compiled by Culture Volcan, showed again significant plumes originating from the volcano. This suggests that activity (if any) has been occurring in short-lived pulses rather than continuously.
