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.

Soil-temperature measurement at Hot Creek in Long Valley Caldera, California.

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.

Bubbling Spring, a feature of Hot Creek in the Long Valley Caldera, California, occasionally "boils" due to high water temperature.

Helicopter dropping off monitoring equipment at Mount St. Helens, Washington.

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.

Incandescence from the lava lake surface (out of view) reflects an awesome glow on the gas plume rising from the lake surface.

Hydrothermal explosion at Biscuit Basin in Yellowstone National Park. These types of events are the most likely explosive hazard from the Yellowstone Volcano.

HVO field crews collect temperature data on ground cracks in the Leilani Estates subdivision near the fissure complex. On this day, temperatures ranged from from 100 to 145 degrees C (200 to 300 degrees F), consistent with past readings.

The summit plume from Halema‘uma‘u Crater (elevation 3,670 feet), hugs the southeast flank of Mauna Loa as it is blown by the northeasterly trade winds toward the southern point of the Island of Hawai‘i.

Lava from the Pu'u 'Ō'ō-Kupaianaha eruption, active since 1983, enters the ocean on the south flank of Kīlauea Volcano.
