The lava lake on the northeastern edge of the Pu‘u ‘Ō‘ō crater floor is about 30 m (100 ft) across. It's level rises and falls with changes in pressure in the magma storage body beneath Pu‘u ‘Ō‘ō. Today, the lava lake was at a relatively low level, compared to its condition over the last few months.

Several openings on the floor of the Pu‘u ‘Ō‘ō crater and along the Peace Day flow tube system continue to degas profusely. The only visible lava, however, is the small lava lake confined to a pit on the northeastern side of the crater floor. The lava lake has been present for the last several months.

Back at the USGS Cascades Volcano Observatory office, these data are merged with airborne LiDAR data to calculate lake volume.

A view of the lava lake within the Halema‘uma‘u Overlook vent on an unusually clear day (May 16, 2012) with the Jaggar Museum and the HVO building in the distance.

A narrow channelized flow cascades down the steep lower portion of the pali in Royal Gardens subdivision. This flow was close to the former location of Paradise St.

Lava flows remain active on the pali and coastal plain, but the flow front has made no significant progress towards the ocean over the past week. This image is a composite of a thermal image and a normal photograph, with active breakouts shown by yellow and white areas, and recent, but inactive, flows shown in red and purple.

View of Pu‘u ‘Ō‘ō crater, looking southwest. In the foreground, an active, spattering lava pond is contained within a collapse pit near the east rim of the crater. Two additional vents, both emitting fume, can be seen behind the fume from the lava pond.

Lava flows remain active on the pali and coastal plain, and continue to slowly migrate towards the ocean. This thermal-visual composite shows the distribution of active flows, which are extensive and consist of several lobes. The active flow front today was 1.1 km (0.7 miles) from the water.

A close-up of the lava pond in the eastern portion of Pu‘u ‘Ō‘ō crater. The lava pond is about 30 meters (100 ft) in diameter. The dark lava flows at the bottom of the photo are crater overflows that swept down the east flank of Pu‘u ‘Ō‘ō in September 2011.

This false-color satellite image shows the ongoing lava flow activity on the east rift zone of Kīlauea volcano along with nearby cities and towns on the east side of the Big Island. The image was acquired at 10:28 am on June 12 by the Advanced Land Imager sensor aboard the NASA Earth Observing 1 satellite.

This composite image combines a thermal image with a normal photograph, and shows the recent breakouts on the pali and coastal plain in Royal Gardens subdivision. The two large vegetated areas in this view are some of the only remaining portions of Royal Gardens not covered by lava.

A major eruption of Mount Hood would pose a great hazard to the regional economy.

A circular lava pond has recently been active near the eastern rim of Pu‘u ‘Ō‘ō crater. Today, the lava pond had low-level but continuous spattering from its eastern margin, and a mostly crusted lava surface.

The lava flows on the coastal plain are still slowly advancing towards the water. On today's overflight, the active breakouts were about 750 m (0.5 miles) from the ocean. These flows have once again entered the National Park.

Preview image for video: shows the impressive spattering at the western margin of the lava lake at Halema‘uma‘u. The continuous spattering is often punctuated by bursts which throw lava onto the ledge (left portion of image), and this accumulating lava is building a spatter rampart.

The spatter from the lava lake was landing, in part, on the ledge adjacent to the lake, and then flowing away in a small channel toward the southern side of the vent where it was ponding and cooling. Notice the wrinkled crust on the surface of the lake.

The lava lake at Kīlauea's summit was about 65 m (215 ft) below the floor of Halema‘uma‘u crater today, with impressive spattering along its western edge.

The level of the lava lake at Halema‘uma‘u has been relatively high over the past two days, following summit inflation, with lava close to the level of the deep inner ledge. Continuous spattering at the southern lake margin tosses spatter onto the crusted lake surface as well as onto the rim of the ledge, building a steep spatter rampart (left side of image).
