By August 17, the breakout which started on August 16 had reached the end Highway 130. The flows, however, had slowed considerably and were making little forward progress.

Lava was only slowly oozing from the edge of the flow adjacent to the road. In this photo, a piece of shrubbery is slowly consumed by the lava.

A close-up view of the lava stream as seen through a lava tube skylight near the top of the Pulama pali. The lava is moving from right to left, and skylight opening is about 1 m (3 ft) across.

Panorama of Pu'u 'O 'o crater from the south rim of Pu'u 'O 'o cone. Active lava flows (light gray) cover much of the crater floor and are erupting from the degassing vent at the far left.

Close-up view of the erupting vent in Pu'u 'O 'o crater. Lava is not visible because it is going directly into tubes beneath the crusted surface to the right and feeding small lava flows near the flow front.

The Puhi-o-Kalaikini ocean entry and delta. The light colored lava on the delta behind the plume is from recent surface flows.

 HVO scientist measures the episode 12 lava fountain height at Mauna Ulu from Puʻu Huluhulu on Dec 30, 1969. The Mauna Ulu eruption marks its 51^st anniversary on May 24, 1969.

This lava fountain, which erupted on September 6, 1969, during the Mauna Ulu eruption, was about 540 m (1770 ft) tall. The tephra cone, eventually named Mauna Ulu, can be seen in the fallout area (right of the fountains. in middle of image). It is now a 121 m (397 ft) tall lava shield in Hawai‘i Volcanoes National Park.

View westward along the Kapoho fault scarp in the village of Kapoho following a swarm of earthquakes in the area. The ground cracking was caused by subsidence of a graben (down-dropped block) that spanned the community.

Great quantities of lava pour from the base of a 480-m-tall (1,575 ft) fountain about 65 minutes after the start of episode 16. Lava discharge at this time was about 1.3 million cubic meters per hour (1.7 million cubic yards), which sent lava over the entire lake by 4:05 a.m.

Aerial photograph shows the Ka‘apuna lava flow erupted from Mauna Loa in 1950 as it advanced through the forest at about 3,000 feet elevation on the morning of June 2. This rapidly moving ‘a‘ā lava flow traveled from the Southwest Rift Zone vent to the ocean in about 17 hours. Earlier flows from this same eruption reached the ocean in as little as three hours.

The Ka‘apuna flow traveled from the Southwest Rift Zone vent (7,800 ft elevation) to the coast in just 17 hours.
