Stromboli (Eolian Islands, Italy): A major explosion occurred yesterday morning that at 05:12 GMT / 07:12 local time, the volcano observatory reported. The explosion occurred in the northern crater area. Lava bombs fell mainly on the upper part of the Sciara del Fuoco. Seismic activity at 05:12 UTC recorded a signal with a higher-than-normal amplitude associated with the major explosion, followed by a phase of moderate increase in amplitude in the first 8 minutes. … [read more] … [show less] The average amplitude of the signal showed a rapid increase, reaching high values during the explosive event, and a subsequent sudden decrease towards medium values, where it remains. No significant changes have been reported in the rate of occurrence of explosive events. Analysis of data from the high-frequency GNSS network shows no significant ground deformation. The overall activity of the volcano (s. att. image) had been set back to medium on 3 June, after it has been at high level for most of May; this is based on a summary of various monitoring data analyzed by volcanologists of the University of Firenze. At the same time, the seismic activity in the southern Tyrrhenian sea has been elevated during the past weeks.
Etna (Sicily, Italy): Near-continuous, but comparably mild ash emissions continue to occur from the Voragine summit crater as our correspondent reports. While no official comment on the activity has been posted (yet) from the volcano observatory, it is obvious that something has changed and the likelihood of more intense activity in the near future has increased. A small swarm of small earthquakes has occurred today under the western flank near Bronte town, with focal depths ranging mostly around 15-10 km depth. Whether this is related to the current activity or whether the quakes indicate magma movements into storage systems below the volcano’s flank at that depth is impossible to determine with certainty from these data alone, but probably, these events are linked in one way or another.
Lewotobi (Flores): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 9000 ft (2700 m) altitude or flight level 090 .
