Breakouts remained scattered northeast of Pu`u `Ō`ō, on Kīlauea's East Rift Zone. This breakout was one of many on the flow field today. The breakout was fairly vigorous at this time as geologists encountered it just moments after it started.

This video describes USGS research utilizing remote thermal imaging cameras to study the extent and impact of mange on wolves in Yellowstone National Park.

A small vent in Pu‘u ‘Ō‘ō crater throws spatter a short distance, building up a small cone around its opening. A thick layer of Pele's hair covers the downwind part of the cone. This vent was also the source of a small lava flow erupted on the crater floor in the past day.

This movie, created from a sequence of HVO webcam images, shows lava erupting from a spatter cone within the south embayment in the Pu‘u ‘Ō‘ō crater (see February 24 image below for location). The activity started around 8:15 a.m., HST, on Wednesday, March 2, 2016, and covered part of the crater floor before ceasing at about 3:00 p.m.

When large rockfalls impact the lava lake, they trigger explosive events that propel volcanic rock fragments (tephra) upward. This morning's event was vigorous enough to hurl incandescent fragments onto the rim of Halema‘uma‘u Crater, about 110 m (360 ft) above the lava lake surface.

A rockfall on the east rim of the summit vent within Kīlauea Volcano's Halema‘uma‘u Crater triggered a small explosive event at 3:51 a.m., HST, on January 8, 2016. Explosive events like this occur more frequently when the lava lake level is relatively high, as it has been this past week—around 30-35 m (100-115 ft) below the vent rim.

Around 2:17 p.m., HST, on January 2, a rockfall from the east rim of the Overlook vent within Halema‘uma‘u Crater at the summit of Kīlauea impacted the lava lake, generating a small explosive event captured by HVO webcams. This Quicktime movie shows the rockfall as seen from HVO and Jaggar Museum.

This Quicktime movie shows the same rockfall as captured by the USGS Hawaiian Volcano Observatory webcam perched on the rim of Halema‘uma‘u Crater. Note the fragments of molten lava flying toward the camera—just one of the hazards that led to the closure of this area.

This Quicktime movie shows spattering at the margin of the summit lava lake in Halema‘uma‘u Crater. Spattering has been common at the lake, and when it occurs is easily visible from the public viewing area at Jaggar Museum. This video shows a closer view from the rim of Halema‘uma‘u, which is closed to the public due to volcanic hazards.

This Quicktime movie shows a small explosive event that occurred at 1:20pm today at the summit lava lake. A collapse of a portion of the Halema‘uma‘u Crater wall impacted the lake and triggered an explosion of spatter. Fist-size clasts were found scattered along the rim of Halema‘uma‘u Crater near the closed visitor overlook.

Quicktime movie of the rockfall and subsequent explosion at 10:20 a.m., HST, on April 28, 2015. Rocks falling into the summit lava lake generated an explosion that threw large fragments of molten lava onto the rim of Halema‘uma‘u Crater, 85 m (280 ft) above the lake.

The lava lake in the Overlook Crater, within Halema‘uma‘u Crater at the summit of Kīlauea Volcano, has been rising over the past few days. Today the lava was as high as 14 meters (46 feet) below the Overlook crater rim. Several areas of spattering were active along the lake margin.

Volcano gas geochemistry has been around for a long time. Scientists can make gas measurements using very large, very expensive Correlation Spectrometers or collect samples in the field and bring them back for analysis in the lab. But it’s possible we’re missing out on a lot of information because our monitoring capabilities don’t include continuous observation.

This Quicktime movie provides a brief aerial overview of the active flow front.

An aerial overview of the position of the flow front

This Quicktime movie, taken at 11:30am, gives an aerial overview of the flow front and its position relative to Pāhoa. The movie is fairly large in size and may take several minutes to download.

This Quicktime movie shows a close-up view of the flow front, and its proximity to Cemetery Rd./AP‘A‘ā St. The transfer station is also shown.
