This lava delta at Lae‘apuki added about 24 hectares (60 acres) of new land to the southeast coast of Kīlauea in 2006, but 6.5 hectares (16 acres) slid into the sea in 2007. White plume marks location of lava entering the sea through a tube whose location is shown by blueish fume in middle right.

Substantial cracks cutting across a lava delta are clear indication that the delta is subsiding as it grows across the unstable pile of interfingering lava flows and fragments built on the steep submarine slope. The larger cracks on this delta are 1-2 m (3-6 ft) wide.

Lava delta at East Lae‘apuki on the southeast coast of Kīlauea Volcano is about 17 hectares (43 acres). The delta extends about 400 m seaward from the sea cliff and is about 850 m long parallel to the shoreline. The steep sea cliff embayment resulted from collapses of earlier deltas; the collapses undermined and took away parts of the cliff.

Embayment of lava delta shows result of collapse. The initial collapse was large enough to send waves washing over much of the east half of the delta, because visibility was completely lost for almost 20 minutes, due to a steam white-out. Note rocky debris hurled by the waves onto the delta surface in foreground.

pāhoehoe lava spilling over sea cliff on south coast of Kīlauea Volcano starts to build a new lava delta. Only three days old, the delta grows slowly as lava spreads over fragmented debris and flows that have accumulated on the steep submarine slope.

Explosive interaction between lava and seawater blasts a tephra jet consisting of steam, hot water, black tephra, and molten fragments into the air. Such explosions are typically directed toward the sea, but many explosions also send a shower of lava more than 10 to 20 m (33 to 66 ft) inland.

Active lava delta at East Lae‘apuki on the south coast of Kīlauea Volcano. White gas plume (right) marks location of lava entering the sea through a lava tube whose location is shown by blueish fume (left and center). In early August 2005, the delta encompassed an area of about 12 hectares (30 acres).

Two bubble bursts explode simultaneously as a consequence seawater mixing with lava in a lava tube beneath surface of a lava delta. Because of the confined conditions in the lava tube, explosive pressures build up as water, heated by contact with molten lava, expands instantly to steam.

Map shows the location of lava flows from Puʻu ʻŌʻō (unshaded), and Kūpaianaha (dark shaded), and Friday's fissure eruption (light shading) on Kīlauea's East Rift Zone. The inset shows the area of the enlarged flow field map and the locations and magnitudes of all felt earthquakes for the past week.

Individual pāhoehoe flow fronts were typically only 10-20 cm thick as they moved through Kalapana. However, the thin leading edges of the flows quickly crusted over and stagnated. As lava continued to push beneath the crust, the cooled surface was lifted up until eventually lava again broke out of the sides and front of the inflated flows.

The left edge of the lava flow is following the inland contours of Hakuma horst, the fault block to the left, which is directing the flow into the heart of Kalapana.

Harry K. Brown Park was originally called "Wai'akolea Park." It was renamed "Harry Ka'ina Brown Memorial Park" in 1953 after Brown, a county auditor, whose ancestral home was in Kalapana. Thick smoke is from burning asphalt.
