Left: A small lava lake, which has been present on the northeast side of Puʻu ʻŌʻō's crater floor for nearly a year, has evolved into a tiny pond perched several meters (yards) above the surrounding crater floor, as pictured here. The pond sits near the top of a mound of lava composed of spatter cones and lava pond overflows. Flows from the pond and other nearby spatter cones have inundated the east rim of the crater, which would normally be visible in the background just behind spatter cone complex shown here. Right: Lava from the tiny lava pond flows directly into a tube on its north side. In this photo, the tube starts at the left edge of the pond and heads toward the heavy fume at the left edge of the photo. This tube carries the lava downslope where it is feeding a slow-moving pāhoehoe flow spreading across a nearly flat-lying plain of ʻaʻā flows at the northern base of Puʻu ʻŌʻō.

Left: Since the beginning of the year, lava erupting from several openings in Puʻu ʻŌʻō's crater have filled the crater to overflowing. The two eastern-most openings, topped by spatter cones, can be seen in this photo. The one in the background holds the small lava pond shown in the photos above and feeding the northern lava flow. The east rim of the crater, which wraps around from the rim in the foreground (the south rim) to the rim in the background near the upper left side of the photo (the north rim), has been completely buried. Right: This photo, captured fortuitously, shows a lava flow seconds after it burst from the side of a low tumulus. While initially relatively fast-moving, the flow slowed to a crawl within a few minutes, matching the very slow advancement rate seen elsewhere along the front of the flow.

Left: The eastern rim of Puʻu ʻŌʻō is no longer visible, having been buried by flows mostly from the small lava lake on the northeast side of the crater floor. A mound of lava with a complex of spatter cones, visible in the background, now surrounds the lava lake, which is only visible from the air. Lava from the lava lake is feeding a small lava flow active at the northern base of the Puʻu ʻŌʻō cone. The box in the foreground houses the Puʻu ʻŌʻō Crater webcam shown on the HVO webpage. A time-lapse camera on a tripod is visible on the crater rim in the distance. Right: The lava flow fed the northeastern lava lake in Puʻu ʻŌʻō remains weakly active at the northern base of the Puʻu ʻŌʻō cone. The front of the flow is burning lichen on old ʻAʻā flows erupted from Puʻu ʻŌʻō during 1983–1986. The eastern edge of Puʻu ʻŌʻō is at the upper right side of the photo.

Left: Lava flows have spilled from Puʻu ʻŌʻō crater over the past few weeks. One flow went out the southern end of the crater and traveled a short distance downslope to the southeast before stopping. The other flow, coming directly from the small lava lake on the northeast edge of the crater floor, went down the north flank of Puʻu ʻŌʻō and reached to the base of the cone. This flow is still active and its front has gone about 1.4 km (0.9 miles). Right: This photo, identical to the previous one, just includes labels for the flows that spilled from the northern and southern sides of the crater.

Several streams of lava were entering the water near Kupapa`u Point. Here at the eastern end of the ocean entry a narrow stream is battered by the surf.

Breakouts near the shoreline have diminished over the past week, but surface flows remain active closer to the base of the pali on the coastal plain.

The ocean entry near Kupapa`u Point remains active, with numerous streams of lava entering the water over a wide section of coastline.

Left: Only a few scattered breakouts were active near the shoreline, with most of the activity on the coastal plain closer to the base of the pali. This pāhoehoe lobe was active near the east margin of the Peace Day flow field just a few hundred meters (yards) from the coastline. Right: A surge of "blue glassy" pāhoehoe flows out of an inflated flow margin near the shoreline. This type of lava is thought to be stored within an inflating flow for up to a few days, changing its color and texture.

A small pāhoehoe lobe flows into a crack on the coastal plain.

Left: As this pāhoehoe lobe flows into the crack, the surface layer rolls up creating a ropy texture that is common on pāhoehoe flows. Right: A portion of this pāhoehoe flow is channeled into a crack by two surrounding tumuli.

Left: Eruptive activity in Puʻu ʻŌʻō has picked up over the past week. Lava flows erupting sporadically from several places continue to fill the crater and occasionally spill out onto the east flank of Puʻu ʻŌʻō. This view, looking southwest, shows new lava from active and recent flows on Puʻu ʻŌʻō's eastern flank. Many of the flows come directly from the small perched lava lake on the northeast side of the crater floor, visible at the center of the photo. Right: This photo, looking south, shows lava spilling from the small, perched lava lake on the northeast side of Puʻu ʻŌʻō's crater floor. The rim on the east side of the crater, in the background, has been nearly completely buried and is no longer discernable.

Activity at the ocean entry near Kupapaʻu Point has increased slightly over the past several days, with small entry points now spread along the coastline on both sides of the National Park boundary. Whale watching season has also arrived—the splash of whitewater near the bottom center part of the photo is from a breaching whale investigating the ocean entry.

The lava lake in the Overlook vent reached to within 40 m (130 ft) of the Halemaʻumaʻu crater floor before sunrise this morning, before beginning to drop again. The lake level, however, remains high, as can be seen in this photo, looking west. Note the dramatic overhang on the north-northwest side of the vent (to the right).

Left: The small lava lake on the northeast side of the Puʻu ʻŌʻō crater floor produced several short flows since last night (January 9). This morning, two separate flows spilled from the Puʻu ʻŌʻō crater and onto the northeast flank of the Puʻu ʻŌʻō cone. The flows are visible at the lower left side of the photo. Right: Zoomed-in view of the lava lake on the northeast side of the Puʻu ʻŌʻō crater floor.

Left: A breakout from the active lava tube near the base of the pali in Royal Gardens yesterday fed lava onto the coastal plain. This morning, the breakout fed a small ʻaʻā flow, seen in this photo. Several streams of lava from the breakout point are visible in the background. Right: View of the front of the slowly advancing ʻaʻā flow at the base of the pali.

Left: This is a thermal image, looking southwest, showing the active lava flows on the coastal plain. The ocean entry points are to the left, and the breakout near the base of the pali in Royal Gardens is to the right. The active flows near the ocean straddle the National Park boundary (i.e. both inside and outside the Park). Right: Lava continues to dribble over the sea cliff at the coast, where it produces several weak and variable plumes. This is the eastern of two ocean entry areas, and is outside the National Park. The western area, out of sight to the left in this photo, is within the National Park.

A stream of lava cascades down the sea cliff at the ocean entry, near the eastern boundary of the National Park. This spot was one of several where lava was reaching the water.

Left: Looking west at some of the eastern ocean entry points. Right: Numerous small streams of lava were entering the water as they were battered by the surf.

A portion of the lava stream breaks apart on the near-vertical sea cliff.

The ocean entry (at center of image) near Kupapa`u remains active, with a weak and wispy plume. The light colored area on the coastal plain shows the recently active flows.

Left: This thermal image shows the scattered breakouts on the coastal plain and the ocean entry near Kupapa`u. In addition to these coastal plain flows, several breakouts were active near the top of the pali, around the northern boundary of Royal Gardens subdivision. Right: A closer view of the ocean entry, with weak plumes originating from several spots along the coast.

A small collapse this morning of the spatter cone that had built up around the northeast lava pond in Puʻu ʻŌʻō resulted in a brief gush of lava onto the crater floor.

Thermal image panorama showing the Peace Day flow (episode 61) on the coastal plain. The view is to the southwest. The bright areas are active lava, while the less bright areas are warm but inactive flows.

Thermal images of the Peace Day flow (episode 61) on the coastal plain. The bright areas show active flows, while the darker purple areas show the warm but inactive part of the flow. The top image looks northwest; the bottom image looks north. The terminus of the flow was about 175 m (575 ft) from the ocean at mid-day.

Thermal images of the small lava lake at the northeastern edge of the crater floor in Puʻu ʻŌʻō. The view in the top image is to the northeast; the view in the bottom image is to southeast. The lava lake is about 20 m (65 ft) across.

The active flow front today was about 500 meters (0.3 miles) from the shoreline, and still running along the eastern boundary of Hawaiʻi Volcanoes National Park. In this photo, the lava flow passes by another Park boundary marker.
