Lava entering ocean at Kalapana Gardens subdivision, Kīlauea Volcano, Hawai‘i

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.

Aerial view of pāhoehoe flow encroaching on the Kalapana community. Hakuma horst, a raised fault block, is on the left. To the right of the point are fishponds, and to their right, Walter's Kalapana Store and Drive Inn. In the large trapezoidal plot are Mauna Kea Congregational Church and hall.

View looking uphill at surface flows advancing down a steep slope (Pulama pali) between the east rift zone and the coastal plain of Kīlauea Volcano. Overflows from the channel on the right are building levees of pāhoehoe. Within a few days, crust accreting inward from the levees built a roof over the channel, forming a new lava tube.

A thin-walled lava bubble expands and bursts. These "bubble bursts" occur when seawater infiltrates the lava tube system near the shore. Such bubble bursts produce translucent sheets of spatter, or limu o Pele.

Pu‘u Keonehehe‘e and the two small cones immediately to the northwest (left) are among the youngest cones erupted on the volcano, as recent as about 4,000 years ago. The other cones in this view are part of the Laupahoehoe Volcanics, but much older, dating to 70,000 years ago.

The light colored lava flows in foreground are part of the older Laupahoehoe Volcanics, erupted between 70,000 to 13,000 years ago. one of the youngest cinder cones erupted by the volcano,

Explosive interaction between lava and seawater blasts a tephra jet consisting of steam, hot water, black tephra, and molten fragments into the air. This explosion is directed primarily toward the sea, but many explosions also send a shower of lava more than 10 to 20 m inland.

Bystanders watch steam rising from Queens Bath as lava flow enters the water. Lava overran Highway 130 at 0748 Hawaii Standard Time on the same morning at the western margin of the Kapa'ahu flow. By the end of the day, Punalu'u heiau was overrun, and Queens Bath was filled with lava.

Lava fragments ejected by lava fountains are called tephra, a general term for all fragments, regardless of size, that are blasted into the air by explosive activity. A variety of terms are also used to describe specific types of fragments, including Pele's hair, Pele's tears, scoria, spatter, bombs, and reticulite.

Lava production from these "2,900-m vents" began to decrease in late March but declined most rapidly between April 7 and 9 from about 300,000 m3 per hour to less than 100,000 m3 per hour. Photo taken at 9:09 a.m.
