Map showing the extent of lava flows erupted during Kīlauea's ongoing east rift zone eruption and labeled with the years in which they were active.

Picture showing the increased size of the sandbar after the November 2012 controlled flood from the Glen Canyon Dam. This location is 65 miles downstream from Lees Ferry and the view is looking downstream. These and additional photographs depicting the results of the recent controlled floods can be viewed online.

pāhoehoe flows are still active on the coastal plain but have advanced little over the past week. On today's field visit, the active flow front was about 1.3 km (0.8 miles) from the ocean. In the background, the remains of Royal Gardens subdivision can be seen on the pali, with the fume sources marking the path of the lava tube.

The lava lake fills Overlook crater, about 160 m (525 ft) across, contained within Halema‘uma‘u Crater. The walls of Halema‘uma‘u Crater show white in the middle distance, while the USGS Hawaiian Volcano Observatory and NPS Jaggar Museum, perched on the edge of Kīlauea Caldera, are visible as a small bump on the horizon.

Incandescent lines mark the boundaries between migrating crustal plates on the surface of the lava lake in Halema‘uma‘u crater. Here, and at other lava lakes across the world, these rifting zones have a characteristic zigzag pattern.

Vigorous spattering was present this evening along the western margin of the summit lava lake. Occasional bursts, like the one shown here, appeared to send tiny bits of spatter up to the level of the floor of Halema‘uma‘u crater.

The lava lake in the 'overlook' vent in Halema‘uma‘u reached to within 38 m of the crater floor, filling the entire bottom of the vent.

Dust from a small rockfall coats a small section of the lava lake surface and wafts above the rockfall's impact scar.

A rebound splash from a small impacting rock jets several meters above the lake surface.

Students participate in the Great Southeast ShakeOut earthquake drill at Langston Hughes Middle School in Reston, Virginia. They are conducting the "drop, cover and hold on" safety procedure.

Lava erupting from a vent on the northeast flank of Pu‘u ‘Ō‘ō travels through tubes to the coastal plain, where surface flows are currently active. Holes in the roof of the lava tube, called skylights, reveal the lava stream contained within.
