A clear view today of Pu‘u ‘Ō‘ō's summit revealed no significant change during the past week. The cross-sectional area of the active lava stream in the tube on the flank of Pu‘u ‘Ō‘ō was the same as measured on December 22, suggesting no change in lava discharge from the vent.

Kīlauea's East Rift Zone lava flow remains active upslope from the Pahoa Marketplace area, visible at lower right. The leading edge stalled on December 22, but breakouts just upslope widened the flow field and then overtook the flow front during the past few days. The new leading edge advanced the flow front about 150 m (165 yd) since December 27.

This large-scale map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of Kīlauea's active East Rift Zone lava flow. The area of the flow on December 22 at 3:00 PM is shown in pink, while widening and advancement of the flow as mapped on December 30 at 2:30 PM is shown in red.

Close view of incandescence in spatter cone within a pit at the northeast edge of Pu‘u ‘Ō‘ō's crater (the smaller pit visible to the right side in the adjacent photograph). Note small flows that cover the floor of this small crater.

This satellite image was captured on Thursday, December 25, by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds.

This small-scale map shows Kīlauea's active East Rift Zone lava flow in relation to lower Puna. The area of the flow on December 19 at 8:30 AM is shown in pink, while widening and advancement of the flow as mapped on December 22 at 3:00 PM is shown in red.

A breakout from the lava tube has also been active on the upper part of the flow field near Pu‘u ‘Ō‘ō since December 5. The smoke is from a narrow finger of lava burning lichen on an older Pu‘u ‘Ō‘ō lava flow. Pu‘u ‘Ō‘ō is at upper right. The view is to the south-southwest.

This photo shows a closer view of the picturesque breakout at the narrow section of the flow.

This large-scale map shows the distal part of Kīlauea's active East Rift Zone lava flow in relation to nearby Puna communities. The area of the flow on December 19 at 8:30 AM is shown in pink, while advancement of the flow as mapped on December 22 at 3:00 PM is shown in red.

Kīlauea's East Rift Zone lava flow remains active upslope from the Pahoa Marketplace area, visible at upper left, though activity has waned over the past week. The flow was very close to a firebreak road cut several months ago. The Pahoa Transfer Station is at upper right. The view is to the southeast.

A small, but fairly vigorous, breakout was active this afternoon about 1 km (0.6 miles) behind the tip of the flow. This is the narrowest part of the flow, with a width of about 30 m (33 yards). The smoke in the distance is from surface lava near the front of the flow. The view is to the northeast.

This compares a normal photograph of the active flow front with a thermal image. The white box shows the rough extent of the thermal image. In the thermal image, white and yellow pixels show areas of active breakouts. The thermal image shows that small breakouts are present near the leading tip of the flow, and that many other breakouts are active upslope.

Breakouts were also active much farther upslope. Leaks from the lava tube near the True/Mid-Pacific geothermal well site (at left) have been active for a couple of weeks, and are slowly invading forest to the north. View is to the west-southwest.

This photo gives the general appearance of the surface of the flow, looking upslope, where the flow is narrower on slightly steeper terrain. It is normal for trees within the flow path to not burn after they topple. By the time the trees fall over, the surface crust of the flow has cooled below their ignition temperature.

Kīlauea's East Rift Zone lava flow continues to advance downslope toward the Pahoa Marketplace. This photo is of a small breakout from the edge of the inflated flow several hundred meters (yards) back from the active front.

This large-scale map shows the distal part of Kīlauea's active East Rift Zone lava flow in relation to nearby Puna communities. The area of the flow on December 16 at 11:15 AM is shown in pink, while widening and advancement of the flow as mapped on December 18 at 11:15 AM is shown in red.

This photo looks downslope towards Highway 130. The leading tip of the flow has widened over the past few days, and branched into two fingers - both of which are heading in the same general northeast direction.
