Map showing the June 27th flow in Kīlauea's East Rift Zone as of August 25, 2014. The area of the flow as mapped on August 22 is shown in pink, while widening and advancement of the flow as of August 25 is shown in red. The brown line marks the ground crack that channeled lava to the east, where it emerged to form a new pad of lava over the past couple of days.

The area of the flow as mapped on August 12 is shown in pink, while widening and advancement of the flow as of August 22 is shown in red. The heavy brown line marks the extent of steaming along a ground crack into which lava is flowing.

After the June 27 breakout started, a perched lava pond - looking something like a giant above-ground swimming pool - grew over the main vent. Notice the nearly flat upper surface of the now-inactive pond just above and to the left of center, and the relatively steep levee which contained the pond.

Map showing the Kahauale‘a 2 flow (pink) in relation to the eastern part of the Island of Hawai‘i as of June 17, 2014. The most distant active Kahauale‘a 2 lava flows were 7.1 km (4.4 miles) straight-line distance northeast of Pu‘u ‘Ō‘ō.

As noted above, the new flows have caused withdrawal of magma within Pu‘u ‘Ō‘ō and small collapses of the several cones on the crater floor.

The withdrawal of magma from within Pu‘u ‘Ō‘ō, to feed the new flows, has caused minor subsidence of the Pu‘u ‘Ō‘ō crater floor since this morning. This was associated with small collapses at the spatter cones on the crater floor.

Map showing the Kahauale‘a 2 flow in relation to the eastern part of the Island of Hawai‘i as of April 28, 2014. The most distant active front of the Kahauale‘a 2 flow was just over 8.3 km (5.2 miles) straight-line distance northeast of Pu‘u ‘Ō‘ō. Two other flows were also active on the flanks of Pu‘u ‘Ō‘ō, each erupting from a different vent.

The Kahauale‘a 2 lava flow, as of April 18, 2014, is shown in pink, with a yellow line indicating the active lava tube. The most distant active front of the flow retreated over the past week, probably in response to a DI event. The area covered by older lava flows erupted from Kīlauea in 1983-2013 is shown in gray.

Map showing the Kahauale‘a 2 flow in relation to the eastern part of the Island of Hawai‘i as of April 18, 2014. The most distant active front of the Kahauale‘a 2 flow had retreated slightly, probably in response to a DI event which occurred at Kīlauea's summit over past week, and was 7.5 km (4.7 miles) northeast of Pu‘u ‘Ō‘ō.

Map showing the Kahauale‘a 2 flow in relation to the eastern part of the Island of Hawai‘i as of April 7, 2014. The active front of the Kahauale‘a 2 flow was 8.2 km (5.1 miles) northeast of Pu‘u ‘Ō‘ō and advancing very slowly through thick forest.

Scanning Electron Microscope images, collected at UH Hilo, showing a fragment of lava collected from the Pu‘u ‘Ō‘ō lava pond in November 2013. The bar scale at the right is 300 microns (0.012 in). The mostly uniform light gray is basalt glass and darker gray crystals are olivine (left) and pyroxene (right).

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.
