Activity of the Poas, Turrialba, Copahue, Sakurajima, Nishinoshima, Sinabung, Kilauea and Loihi volcanoes.

In Costa Rica, after the discovery of abnormal thermal manifestations noticed on the ground by the volcanologists G.Avrard and J.Pacheco on June 28th, the Poas showed, during the early hours of June 1, an eruptive activity characterized by ejection of magmatic blocks, of metric size, at several tens of meters; These incandescent blocks have fallen back into the active crater, mainly in the vicinity of the ancient lake. The activity lasted from 1:14 to about 5:00 local time.
