This image was acquired by the Earth Observing 1 satellite's Advanced Land Imager sensor on February 2, and shows Kīlauea's summit and east rift zone. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see.

During the first few hours of the Kamoamoa fissure eruption in March 2011, lava bubbled to the surface through a ground crack that propagated along Kīlauea Volcano's East Rift Zone. How it and other Hawaiian fissure eruptions work will be the topic of a talk at UH-Hilo on January 16, 2014.

It was remarkably clear during today's overflight of Kīlauea's east rift zone. This photo is taken from Pu‘u ‘Ō‘ō, and looks northwest. Mauna Kea is at the right, and Mauna Loa is at the left. In front of the summit of Mauna Loa, the degassing plume from the lava lake at Kīlauea's summit is rising vertically.

The Hawaiian Volcano Observatory (HVO) and Jaggar Museum are located at the summit of Kīlauea Volcano, and are visible atop the cliff to the right, on the edge of Kīlauea Caldera. HVO is about 2 km (1.25 miles) north-northwest of the lava lake in Halema‘uma‘u, fuming (but not directly visible) at the left edge of the photo.

At 9:48 PM on Friday, August 23, 2013, a collapse of a piece of the wall above the lava lake in Halema`uma`u triggered a small explosion. The explosion bombarded the rim of Halema`uma`u around the old visitor overlook with molten gobs of spatter as big as dinner plates.

Lava enters ocean at Kupapa‘u Point, Kīlauea Volcano, Hawai‘i. Photographed with a telephoto lens, the safest way to view the interaction of lava and seawater on the edge of an active delta.

On Kīlauea's East Rift Zone, the Kahauale'a 2 flow advances slowly into the Puna Forest Reserve. The Kahauale`a 2 flow began in early May, 2013, on the north side of the rift.

The Kahauale‘a 2 flow remains active north of Pu‘u ‘Ō‘ō, and has expanded a very minor amount into the forest, burning trees. The flow, which consists of slowly moving pāhoehoe, has widened but advanced little over the past two weeks.

Do not be misguided by the risky actions of this person (upper right), who is standing on an active lava delta that could collapse without warning, amidst a plume of superheated steam, hydrochloric acid, and tiny particles of volcanic glass. To avoid these ocean entry hazards, HVO advises staying at least 400 m (one-quarter mile) from where lava enters the sea.

Pele's hair covers much of the ground in the area immediately downwind of the vent at Halema‘uma‘u Crater. Accumulations about a meter (yard) wide are found on the windward sides of the curbs in the Halema‘uma‘u parking lot, which is closed to the public because of the ongoing volcanic hazard (May 3, 2012).

An active lava lake is contained within the Overlook crater, within Halema‘uma‘u Crater at the summit of Kīlauea Volcano. The summit eruption began on March 19, 2008, and is now nearly five years old. The Hawaiian Volcano Observatory and Jaggar Museum are visible as a small bump on the horizon in the upper right portion of the image.

Kīlauea Volcano's summit vent within Halema‘uma‘u Crater was more than 500 feet across in March 2013, five years after it opened.

Lava fountains, occasionally surging to heights of 45-55 m (150-180 ft), erupted south and north of Keanakāko‘i Crater (top and middle fissures, respectively) and on the floor of Kīlauea Caldera (foreground fissure) in a spectacular summit eruption on July 19, 1974.
