September 1974 Halemaʻumaʻu Eruption

The September 1974 Halemaʻumaʻu eruption was a brief but intense summit event at Kīlauea, erupting from fissures within the crater in a similar location to the 1971 eruption. Unlike the July 1974 eruption, this event featured a “curtain-of-fire” style lava fountain that advanced rapidly but stopped abruptly at the southwest wall of the caldera.
