September 1982 Kaluapele Eruption

The September 25, 1982, Kaluapele eruption was a brief but vigorous event that followed nearly two hours of seismic unrest and rapid summit inflation. Lava erupted from a 1,150-foot-long fissure near the southern end of the caldera, producing fountains up to 220 feet high. The eruption quickly formed a lava pond that overflowed the caldera rim, sending lava about one mile southward and briefly crossing Crater Rim Drive.
