This photo captures volcanic lightning within incandescent ejecta from the Irazú summit crater in 1963. Intermittent ejection of ash, lapilli, blocks, and bombs took place for two years beginning from March 1963. Late in 1963 an ash plume reached 8 km above the vent in four minutes.  Photo by M. Esquivel, 1963 (published in Barquero, 1998).
