Stromboli (Italy) - Report for 5 September-11 September 2018

INGV reported that during 3-9 September activity at Stromboli was characterized by ongoing Strombolian activity and degassing from multiple vents within the crater terrace.
Explosions mainly from two vents (N1 and N2) in Area N (north crater area, NCA) and three vents (C, S1, and S2) in Area C-S (South Central crater area) occurred at a rate of 2-15 per hour.
Low-to-medium-intensity explosions from the N1 vent ejected lapilli and bombs mixed with ash as high as 120 m.
Explosions of variable intensity at the N2 vent ejected tephra 150 m high.
Vent C produced gas emissions, and periodic low-intensity explosions ejected tephra 80 m high.
Incandescent material from S1 jetted 120 m above the crater.
Low-intensity explosions at S2 ejected tephra less than 80 m high.
