Dukono (Halmahera): Ash plumes were detected at the volcano during the past days, suggesting that activity is relatively intense at the moment.
Turrialba (Costa Rica): A new phase of explosive activity occurred at the volcano during the past days. It has calmed down again since yesterday, but new eruptions could (and are likely to) occur any time. Steaming and incandescence are visible from the crater.
Following some weeks of calm, the volcano began again to erupt small plumes of ash again on 3 April, followed by more intense explosions on Easter Sunday, producing dense ash plumes of approx. 500 m height.
Abundant ash fall occurred on the western slope of the volcano and light dusting occurred in up to 35 km distance. Access to the volcano has been closed.
Reventador (Ecuador): A larger explosion seems to have occurred about an hour ago. On the thermal webcam, the upper cone is seen covered with incandescent ejecta.
