Aerial view of the Waikupanaha (large plume) and West Waikupanaha ocean entries. The West Waikupanaha entry spans the coastline where the numerous small, wispy plumes are visible. The entries remain active as lava continues to enter the ocean through both lava tubes and surface flows.

Standing at the former time lapse camera site on the rim of Pool 1 of the perched channel, geologists measure the depth of the March 2009 collapse. A hammer head was attached to a steel cable and lowered over the edge until it hit the floor of the collapse pit. When the hammer hit the bottom, the cable was marked, and the depth was measured at 16.5 m (54 ft) deep.

At the Waikupanaha ocean entry (left), three separate steam plumes merge into one as the wind blows the steam offshore. The west Waikupanaha entry is spread out over a larger area with at least 5 separate lava entry points. This photo was taken looking southeast.

Scattered breakouts, like the one shown here, continue to be active on the coastal plain and are situated west of the main Waikupanaha tube and just inland of the west Waikupanaha ocean entry.

This photo is looking east towards the three ocean entry points active today. The most distant, and most vigorous, is the Waikupanaha entry, which has been active since March 2008. In the foreground are two entry points at the west Waikupanaha entry area, which has been active over the past few weeks.

A small open channel of lava was entering the water at one of two entry points at the west Waikupanaha entry area.

Surface activity continued in several small areas above the Kalapana access road, burning more vegetation in the forested kipuka. The trailhead to the county viewing area sits at the end of what remains of the access road, shown here at the top-middle portion of the photograph.

Lava continues to flow into the ocean at the well-established Waikupanaha ocean entry. About 700 m to the west (up the coastline in this photograph), the new ocean entry puts off a small plume that is barely visible from this vantage point.

On the east margin of the entry, lobes were advancing over a small black sand beach.

Breakouts continued near the County lava viewing trail. This breakout, which is burning a downed hala tree, was about 300 m west of the trailhead.

Several collapses early this morning exposed more of the lava pond deep within the Halema`uma`u vent cavity. For the last several days, glowing and spattering holes (top image) have been active on the floor of the vent cavity, at a depth of about 200 m below the vent rim.

Scientists from the USGS Alaska Volcano Observatory (AVO) examine deposits on the lobe of the Drift Glacier with the summit of Mount Redoubt and its steaming lava dome in distance.

Hot Creek Gorge viewed upstream toward the southwest; the steep walls of the gorge consist of a single rhyolite lava flow erupted from a vent 4 km (2.5 mi) to the south.

The "spider" (a self-contained portable instrument package) was engineered and deployed during the 2004-2008 eruption of Mount St. Helens to detect and triangulate shallow earthquakes, monitor local ground deformation and uplift, detect lightning that might indicate an ash eruption and low frequency sound from explosions.

HVO geologists noted persistent spattering in the northeast corner of the lava lake within the Overlook vent during their night-time observations. The view of the lake surface was fairly good because of fume in the area of the Overlook was "thin" at the time.
