The April 30, 1982, Kaluapele eruption was a short-lived summit event that lasted about 19 hours. Lava erupted from a 3,200-foot-long fissure northeast of Halemaʻumaʻu crater, producing low fountains 15–30 feet high, with bursts up to 160 feet.

The November 16, 1979, eruption near Pauahi Crater was a brief, one-day event on the upper East Rift Zone. It was preceded by two months of increased seismic activity, summit inflation, and lava erupting from fissures west of, within, and east of the crater.

The September 1977 eruption of Kīlauea began after nearly two years of dormancy, with activity breaking out on September 13 along a 3.5-mile-long fissure system between the prehistoric cones of Kalalua and Puʻu Kauka.

The July 19–22, 1974, Keanakākoʻi eruption was a dramatic summit event triggered by a sudden increase in seismicity and summit deflation. Lava fountains up to 180 feet high erupted from fissures north and south of Keanakākoʻi Crater and on the caldera floor, sending lava flows about 1.5 miles southward and across the caldera floor.

The February 1969 rift eruption near Nāpau Crater was a brief but dynamic precursor to the long-lived Maunaulu eruption that began in May of that year. This week-long event featured lava fountaining from multiple fissures along a 2.5-mile stretch of Kīlauea’s upper East Rift Zone.

The 1961 fissure eruption near Nāpau Crater was a short-lived but notable event on Kīlauea’s East Rift Zone, occurring in late September. Over two days, lava erupted from vents along a 13-mile stretch, producing 13 small flows and lava fountains that reached heights of up to 400 feet, with the largest flows occurring near Pāhoa.

The July 1961 eruption at Halemaʻumaʻu was the third summit eruption of that year, continuing the pattern of vigorous volcanic activity at Kīlauea. This event featured sustained lava fountaining and further infilling of the crater, building upon the changes initiated by the February and March eruptions.

The February 1961 summit eruption of Kīlauea marked the beginning of a year of intense volcanic activity, characterized by three distinct summit eruptive phases.
