Kalapana Gardens subdivision inundated by pāhoehoe flows, Kīlauea Volcano, Hawai‘i

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.

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.

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.

Lava flows from a lava tube into the sea near Kupapau Point on 11/27/1989. From the Kilauea East Rift Zone (ERZ) eruption, eruption pisode 48, Kupapau lava flow. Hawai'i Island.

Pahoehoe ropes form in the Wahaula Lava Flow across from Wahaula Visitor Center on Hawai'i Island during the Kilauea East Rift Zone (ERZ) eruption on 6/15/89.

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.

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.

Aerial view, from the east, of waning lava fountain from Pu'u 'O'o on Hawai'i Island's Kilauea Volcano. Taken at the end of eruption episode 32. Pu'u 'O'o rose 209 meters above the pre-1983 surface (928 meters above sea level).

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.

Low fountain, approximately 50 meters high, from Pu'u 'O'o on Hawai'i Island's Kilauea Volcano (viewed from the north). Lava issuing from the breach in the northeast rim of the crater produced an 'a'a flow that extended more than 4 kilometers. Eruption episode 8.

Pu'u 'O'o fountain approximately 100 meters high during eruption episode 8 on Hawai'i Island's Kilauea Volcano. Dark clots of spatter land near the base of the fountain, contributing to the growth of the cone. Less dense cinder, visible in the upper right, is carried downwind of the cone.

Accretionary lava ball comes to rest on the grass after rolling off the top of an 'a'a flow in Royal Gardens subdivision on Hawai'i Island's Kilauea Volcano. Accretionary lava balls form as viscous lava is molded around a core of already-soldified lava.

View at dusk of the young Pu'u 'O'o cinder-and-spatter cone, with fountain 40 meters high, on Hawai'i Island's Kilauea Volcano (episode 5).

Arching fountain of lava approximately 10 meters high issuing from the western end of the 0740 vents, a series of spatter cones 170 meters long, south of Pu'u Kahaualea on Hawai'i Island's Kilauea Volcano (episode 2). Episodes 2 and 3 were characterized by spatter and cinder cones, such as Pu'u Halulu, which was 60 meters high by episode 3.

Forest of lava trees resulting from eruption of a 1-km-line of vents east of Pu'u Kahaulea on Hawai'i Island's Kilauea Volcano. The bulbous top of each lava tree marks the high stand of the lava flow as it spread through the trees.

Lava fountains erupt from fissures during the first week of the Pu‘u ‘Ō‘ō eruption south of Pu‘u Kahaualea, approximately 2.4 km (1.5 miles) northeast of where subsequent eruptions built the Pu‘u ‘Ō‘ō cone. The early fissures cut through old forested lava flows in a remote section of Kīlauea's east rift zone.

The crater is about 2 km (1.2 mi) wide and the floor is about 600 m (1,970 ft) below the crater rim.
