A Scroll down to the photo taken on June 29 to compare the amount of uplift the floor of the crater has endured in the last month. This photo was taken from a similar spot to the lower right of the three photos posted that day.

Aerial view looking southwest into Pu‘u ‘Ō‘ō crater with its lava lake (shiny surface) perched 5-8 m above the surrounding lava flows.

View toward the southeast of lava erupting from a spatter cone on the northeast part of the Pu‘u ‘Ō‘ō crater floor. The Pu‘u ‘Ō‘ō Webcam is visible on the rim of the crater near the bottom of the photo.

A third view of the erupting spatter cone, from the south.

This composite image shows the west lobes that are active on the coastal plain. The east lobe, shown in the other composite image, extends of view to the right. Like the other composite image shown today, hot colors (yellow, white) show active areas of the flow field, while the cooler colors (red, purple) show recent but inactive flows.

Aerial view of Pu‘u ‘Ō‘ō crater, looking north-northeast. New flows, erupting from a spatter cone just above the center of the photo and a spatter cone to the left of center, have been slowly filling the crater over the past few months.

Viewing looking northeast across Pu‘u ‘Ō‘ō crater. The spatter cone erupting lava flows on to the crater floor over the past few weeks, visible just above the center of the photo, tops the low mound of lava that it has constructed.

Aerial view of the Ki ocean entry with several narrow streams of lava pouring into the ocean.

Spatter being ejected from the newly formed vent.

The lava pond in the vent cavity of the Halema‘uma‘u Overlook vent during the rise phase of a rise/fall cycle. In this photo, the lava pond is 95 m (312 ft) below the floor of Halema‘uma‘u crater. When the pond level is high there is very little fume, allowing for unusually clear views.

A small lava flow erupted from the septum between two vents on the east wall of Pu‘u ‘Ō‘ō crater on Sunday, February 6. The hole on the right, which is no longer active, was the original east wall vent. The fuming hole behind the new lava flow is the current east wall vent.

Flows from the more northerly vent are crossing a small portion of the crater floor and filling in the southern opening.

A close-up of the northeast vent in Pu‘u ‘Ō‘ō, spattering and sending lava flows into the crater.

Overflows from the lava pond in Pu‘u ‘Ō‘ō have nearly leveled the crater floor with the perched pond. The floor of the crater is now 39 m (128 ft) below the east rim.

Another view of the erupting spatter cone in Pu‘u ‘Ō‘ō, this one looking toward the west.

Aerial view down into the vent in Halema‘uma‘u with the active lava lake at the bottom. Lava is upwelling at the upper right side of the lake (north) and downwelling at lower left (south).
