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.

View looking south across Newberry caldera towards the Big Obsidian flow (left of center) and Paulina Peak, with Paulina Lake in foreground. Photo taken from the north rim of the caldera.

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.

Near-vertical view down into the Overlook vent collapse crater. The partly destroyed visitor overlook is at lower right. The gray surface of the lava lake at the bottom of the pit is faintly visible through fume. North is toward the top of the photo.

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.

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

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

A new ocean entry started overnight, fed by a western branch of the active flow. The light gray-colored new flow shows up well in the cloud shadow at left edge of the photo. An eastern branch of the flow continues to advance slowly toward Kalapana Gardens, which is visible at the upper right.

This composite image combines a thermal image with a normal photograph of the coastal plain and pali. The active flow field is split into several lobes, and this image shows the eastern lobe that has been approaching Kalapana Gardens subdivision. Active lava has reached the end of the paved access road, where the County lava viewing area is.

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 looking south toward a lava flow advancing through forest along the Roger James fishing access road. The recently active Puhi O Kalaikini delta is to the left. The current ocean entry at Ki is at upper right.
