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.

A closer look at the breakout points of today's new activity. The lava erupted from several fissures which broke through, and slightly uplifted, older lava on the cone.

Another view of the spatter coating the area around the breakout point.

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. A partial collapse of this cone revealed a small pond of lava just below the surface.

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. Dropping lava levels in the northeast lava pond in Pu‘u ‘Ō‘ō crater caused collapses and enlargement of the pond, which has nearly claimed the time-lapse camera (left side of images) observing the lava pond.

Spattering was occurring at three locations along the edge of the lava lake during today's overflight. Spattering like this is common, can occur anywhere around the lake margin (though it most often occurs at the southeast edge), and repeatedly starts and stops. View is toward the southeast.

The Kahauale‘a 2 flow remains active northeast of Pu‘u ‘Ō‘ō. Today, its most distant tip, in the foreground of this photo, was burning into the forest 7.0 km (4.3 miles) from its source at Pu‘u ‘Ō‘ō. View is toward the southwest.

The fuming spatter cone near the center of the photo is informally called the "Northeast spatter cone", and is the source of the Kahauale‘a 2 flow. Lava reaches the surface at that point and flows directly into a lava tube, which feeds the active flows downslope. View is toward the west.

While the top of the Northeast spatter cone is often open, revealing a small lava pond (see photo from June 6, 2014), today its top was sealed shut. This has happened several times over the past year, and is likely a temporary situation. View is toward the northwest.

The summit lava lake, its surface composed of solidified plates separated by incandescent seams, was about 42 m (138 ft) below the floor of Halema‘uma‘u today. The mostly destroyed visitor overlook is at the left side of the photo, on the rim of Halema‘uma‘u. View is toward the west.

Beryl Spring's strongly boiling blue pool is about 8 m (25 ft) wide and contains high-chloride liquid water with a near-neutral pH. Immediately behind the pool is a loud, hissing fumarole producing a white cloud of steam. USGS Photo by Pat Shanks, 2002.

Gas bubbles rising through the lava pond create small blisters in the thin flexible crust near the pond margin.
