Roundup of Global Volcanic Activity – New Activity for the week of 22 February-28 February 2017
Etna | Sicily (Italy) : INGV reported that Strombolian activity at Etna’s New Southeast Crater (NSEC) cone that began on 23 January gradually began to intensify at 1700 on 27 February. A lava flow quickly reached the base of the cone and traveled SW towards Monte Frumento Supino. Ash plumes drifted E and caused ashfall in Zafferana and Linguaglossa.
Pacaya | Guatemala : INSIVUMEH reported that during 21-28 February weak Strombolian explosions at Pacaya’s Mackenney cone ejected material as high as 20 m above the crater rim. Lava flows traveled 150 m NW towards Cerro Chino cone, and 75 m W.
Piton de la Fournaise | Reunion Island (France) : OVPF reported that during 25-26 February observers noted ejections of material from the active vent at Piton de la Fournaise. Lava was mainly transported through a lava tube, and a few branches coming from the end of the tube remained active. Late at night on 26 February tremor began to decline, and ceased at 1010 the next morning. Mid-day on 27 February observers confirmed that no material was being ejected from the vent, and that only white plumes were rising; gas emissions ceased at 1930.
