Close-up of the channelized breakout, showing the lava stream near the breakout point and the surrounding pahoehoe.

This composite image of the coastal plain near Kalapana combines a thermal image and a conventional photograph. The majority of lava is traveling through the lava tube system to the ocean and is not easily detectable in the image. Sometimes, however, the lava tubes do show a clear thermal signature.

The most recent breakout on the coastal plain, which began on October 15, is still active in several places along its southern margin. The lighter grey lava flows in the middle of the photograph are the extent of the latest activity. The flow is 550 m (1800 ft) long and runs parallel with the trace of Highway 130 (the road on the right side of the photograph).

Near-vertical view into the eruptive vent inset within the southeast edge of Halema'uma'u Crater. The crusting, slowly circulating lava surface was about 115 m (375 ft) below the floor of Halema'uma'u.

A vent opening on the north side of the Pu'u 'O 'o crater floor just after 6 am this morning. By 10:30 am, a lava lake up to 10 m (33 ft) deep had filled the eastern half of the crater.

Another view of the lava lake, this one from the much lower western rim of Pu'u 'O 'o.
