Map showing the June 27th flow in Kīlauea's East Rift Zone as of September 3, 2014. The area of the flow as mapped on September 1 is shown in pink, while widening and advancement of the flow as of September 3 is shown in red. Last night, lava welled up out of the crack it was filling and spilled out onto the ground to feed new surface flows.

Map showing the June 27th flow in Kīlauea's East Rift Zone as of August 29, 2014. The area of the flow as mapped on August 28 is shown in pink, while widening and advancement of the flow as of August 29 is shown in red. All older lava flows (1983-2014) are shown in gray. The thin yellow line marks a portion of the lava tube feeding the flow.

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 June 27, 2014, breakout and the Kahauale‘a 2 flow in relation to the eastern part of the Island of Hawai‘i as of June 30, 2014. The Kahauale‘a 2 flow (pale orange) is no longer active — it was beheaded when the lava level at Pu‘u ‘Ō‘ō dropped with the onset of the June 27 breakout.

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.
