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.

Tilt measured at the summit of Kīlauea during March 1-7, 2012, shows a series of U- and V-shaped DI events, with deflation indicated by downward tilt and inflation by upward tilt. Images from a thermal camera that overlooks the summit eruptive vent demonstrate how the lava level (noted by white dashed line), depicted by warmer colors, charges across tilt cycles.

Lava flows creep through the Royal Gardens subdivision on February 24, 2012, slowly burying the few remaining forested kipuka.

pāhoehoe flows were active on the coastal plain today, but extended only about 400 m (440 yards) out from the base of the pali. These flows have about 2.8 km (1.7 miles) more to travel to reach the ocean. Farther up the hill, on the steep lower portion of the pali, several active ‘A‘ā cascades are visible.

This image of a dusty plume produced by rocks collapsing from the wall of the eruptive vent within Kīlauea Volcano's Halema‘uma‘u Crater was captured by a USGS time-lapse camera on December 21, 2011. Vigorous spattering on the lava lake deep within the vent created the orange glow visible at the base of the plume.

At Kīlauea, when the lava column drops below the water table, groundwater may come into contact with with magma or hot rocks, causing violent steam explosions.
