Kīlauea's July 1974 summit eruption

Lava fountains, occasionally surging to heights of 45-55 m (150-180 ft), erupted south and north of Keanakāko‘i Crater (top and middle fissures, respectively) and on the floor of Kīlauea Caldera (foreground fissure) in a spectacular summit eruption on July 19, 1974. A torrent of lava (largely obscured by fume at lower right) gushed to the caldera floor through a pre-existing gully. USGS photo.
