Zoomed-in view of the lava lake on the northeast side of the Pu‘u ‘Ō‘ō crater floor.

The lava lake in the Overlook vent reached to within 40 m (130 ft) of the Halema‘uma‘u 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).

The small lava lake on the northeast side of the Pu‘u ‘Ō‘ō crater floor produced several short flows since last night (January 9). This morning, two separate flows spilled from the Pu‘u ‘Ō‘ō crater and onto the northeast flank of the Pu‘u ‘Ō‘ō cone. The flows are visible at the lower left side of the photo.

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 ‘A‘ā flow, seen in this photo. Several streams of lava from the breakout point are visible in the background.

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).

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.

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 east face of Middle Sister is 350 m (1150 ft) high. Ice-sculpted pile of lavas at right, variously called "Black Hump," "Prouty Point," or "Step Sister," has 190 m of relief and consists of at least five flows.
