INGV reported that eruptive activity continued at Stromboli during 15-21 April. Webcam images showed Strombolian activity at two vents in Area N (one at N1 and one at N2), within the upper part of the Sciara del Fuoco, and from three vents at S2 in Area C-S (South-Central Crater) in the crater terrace. Weather conditions and technical difficulties sometimes prevented observations.
