An HVO geologist returns from checking on spatter collection trays on the rim of Pu‘u ‘Ō‘ō crater. In the upper right, the active lava pond in the crater is tossing a small amount of spatter into the air. The photo above this one shows a bird's-eye view of the lava pond and this area.

One of the last remaining portions of Royal Gardens subdivision, showing the overgrown remnants of Prince Avenue and Orchid Street. Flows were active on the east (right) side of this kipuka about one month ago, and flows were active today at the northern tip (upper left).

About one month ago, lava spilled westward through this roadcut along Paradise Street in Royal Gardens subdivision, hitting a long-abandoned vehicle and just touching the margin of flows from an earlier episode of the current eruption (lower right).

The western branch of the coastal plain flow field is inflated and more active than the eastern branch. Here, a breakout from a tumulus feeds a ropey pahoehoe flow. The fume in the background on the pali marks the lava flow activity that is feeding the coastal breakouts.

Tilt measured at the summit of Kīlauea during March 1-7, 2012, shows a series of U- and V-shaped DI events, with deflation indicated by downward tilt and inflation by upward tilt. Images from a thermal camera that overlooks the summit eruptive vent demonstrate how the lava level (noted by white dashed line), depicted by warmer colors, charges across tilt cycles.

Thomas A. Jaggar founded the Hawaiian Volcano Observatory in 1912 and served as its Director until 1940. Shown here in 1925, Jaggar is at work in HVO's first building, which, at the time, was located on the northeast rim of Kīlauea Volcano's summit caldera, near the present-day Volcano House hotel.

This panorama, taken from the eastern rim of Pu‘u ‘Ō‘ō crater, shows the broken, jumbled crater floor. In the right portion of the photograph, near the northeast rim of the crater, a collapsed cone hosted a small roiling lava pond today.

Higher up on the flow field, fume marks the trace of the lava tube. In the lower left portion of the photograph, a glowing skylight can be seen. Pu‘u ‘Ō‘ō is visible near the top of the photo.

This thermal image, looking west, shows the meager activity out on the flow field today, due to an ongoing deflation event at the summit. On the coastal plain, the red and orange areas depict flows that have been active over the past two weeks, but are now stalled.

pāhoehoe flows remain active on the upper coastal plain, extending a few hundred meters out from the base of the pali. The activity today was relatively sluggish, likely because of a recent deflation phase at the summit.
