Clean up of ash in Argentina following the Puyehue-Cordón Caulle 2011 eruption.

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.

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 week, the northwest vent was producing lava flows on the floor of Pu‘u ‘Ō‘ō crater. The northeast cone is in the background, as well as the small lava flow that ran down the east wall of the crater.

A new rootless shield is building along the TEB tube above the pali. Lava began erupting in the area on February 4, and has built up a shield and lava pond about 10 m (33 ft) high.

After recovering from last week's DI event, the lava surface in the Halema‘uma‘u Overlook vent returned to about 80 m (260 ft) below the floor of Halema‘uma‘u Crater. The north/northwest rim of the vent (right side of photo) is still noticeably overhung, making future collapses very likely.

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.

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.

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.

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