Piton de la Fournaise (France) - Report for 5 June-11 June 2019 - NEW

Actividad volcánica (SI/USGS) - Mié, 2019/06/12 - 17:52

OVPF reported that a seismic crisis at Piton de la Fournaise began at 0603 on 11 June and was accompanied by rapid deformation. Tremor began at 0635, indicating an eruption, though inclement weather conditions prevented visual confirmation; a gas plume was recorded in webcam images. Scientists observed the eruption during a field visit around 0930, describing at least five active fissures on the SSE flank of Dolomieu Crater. Weather conditions continued to hinder visual observations. Three fissures at relatively lower elevations produced 30-m-high lava fountains and lava flows. Two higher-elevation fissures were no longer active. By 1530 only the lowest-elevation fissure remained active.

Stromboli (Italy) - Report for 5 June-11 June 2019

Actividad volcánica (SI/USGS) - Mié, 2019/06/12 - 17:52

INGV reported that during 3 and 6-9 June activity at Stromboli was characterized by ongoing Strombolian explosions and degassing from multiple vents within the crater terrace. Explosions from two vents (N1 and N2) in Area N (north crater area, NCA) occurred at a rate of 1-4 per hour, ejecting material 80 m high and producing ash plumes. Explosions from two vents (S1 and S2) in Area C-S (South Central crater area) occurred at a rate of 3-8 per hour, ejecting material 80-150 m high. Gas plumes rose from vent C.

Sinabung (Indonesia) - Report for 5 June-11 June 2019 - NEW

Actividad volcánica (SI/USGS) - Mié, 2019/06/12 - 17:52

PVMBG reported that at 1628 on 9 June an eruption at Sinabung produced a dense black-gray ash plume that rose around 7 km above the summit, drifted W and SW, and generated pyroclastic flows that traveled 3.5 km SE and 3 km S. Roaring was heard at the Sinabung observation post. Continuous emissions were visible rising 500 m above the summit for a period on 10 June. The Alert Level remained at 3 (on a scale of 1-4), with a general exclusion zone of 3 km and extensions to 5 km on the SE sector and 4 km in the NE sector.

Etna (Italy) - Report for 5 June-11 June 2019 - NEW

Actividad volcánica (SI/USGS) - Mié, 2019/06/12 - 17:52

INGV reported that explosions at the fissure segment at 2,850 m elevation on the SE base of Etna?s New Southeast Crater (NSEC) declined in frequency and intensity during 3-4 June; explosions ceased on 5 June. The lava flow from the fissure was active only near the vent on 5 June and by the next day had ceased and began cooling. Sporadic ash emissions rose from Northeast Crater (NEC) and quickly dissipated on 6 June. The report noted that the NE edge of the NSEC cone had dropped several meters, likely in conjunction with a period of ash emissions on 30 May. In addition, a hot zone high on the SE flank of the cone that was established prior to the recent eruption was extensively covered with colored fumarolic deposits by 6 June.
