Global Volcanism Program | Image GVP-04246
A series of powerful and deadly explosions on 29 July 1968 initiated a new eruptive period at Arenal volcano. This November 1968 photo shows the destruction to vegetation within a broad, devastated area on the western flank. Ballistic ejecta stripped trees of leaves to distances as far as 5 km west of the summit.
