At the front of the active flow field, several narrow streams of lava were active, reflecting a relatively high level of activity today.

This photograph shows the east rim of Pu‘u ‘Ō‘ō crater. A collapsed spatter cone revealed a swiftly flowing stream of lava heading northeast, into the tube system that supplies the active flow field. The active flows today were 6 km (3.7 miles) southeast of Pu‘u ‘Ō‘ō.

Preview image for video: begins with a view of lava in Pu‘u ‘Ō‘ō made possible by a small collapse pit. The lava is swiftly moving towards the northeast, and this represents lava within Pu‘u ‘Ō‘ō crater that is entering the lava tube system which, in turn, feeds the active flow field.

Erupting vents on Mauna Loa's northeast rift zone near Pu‘u ‘Ula‘ula (Red Hill) on March 25, 1984, sent massive ‘A‘ā lava flows down the rift toward Kulani.

This image of a dusty plume produced by rocks collapsing from the wall of the eruptive vent within Kīlauea Volcano's Halema‘uma‘u Crater was captured by a USGS time-lapse camera on December 21, 2011. Vigorous spattering on the lava lake deep within the vent created the orange glow visible at the base of the plume.

With funding from the American Recovery and Reinvestment Act of 2009, HVO recently upgraded its seismic monitoring network. Here, HVO staff, assisted by an HVO volunteer, installs the solar panel and antenna for one of the upgraded seismic stations on Kīlauea. USGS photo by Janet Babb.

View looking east at a small lava lake filling a depression on the eastern side of floor of Pu‘u ‘Ō‘ō crater. The smooth surface of the lake is just above the center of the photo, and the source of the lava is a hole at the southern edge of the lake (to the right in this view).

Surface flows, visible here as the lighter-colored lava, were active about 4 km (2.5 miles) east-southeast of Pu‘u ‘Ō‘ō, where a low rootless shield is being constructed. This view is looking toward the northwest.

The image shows a gas collection system from the wells at Sulphur Banks. Jaggar made the following note in his daily log: "September, 1940. Dr. S.S. Ballard of the University of Hawaii physics department intiated an improved method of dry gas collection at Sulphur Banks.

A single area of breakouts, visible as the silvery patch in the center of the photograph, was active on today's overflight. These surface flows are high above the pali, about 3.5 km (2.2 miles) southeast of Pu‘u ‘Ō‘ō cone. Pu‘u ‘Ō‘ō is visible in the upper left portion of the image.

A burst of gas from a small vent in Pu‘u ‘Ō‘ō crater throws spatter about 15 m (50 ft) into the air. Over the past week, occasional spattering and short lava flows have been observed within the crater.

This thermal map shows the fissure system and lava flows as of 6 am on Thursday, July 12. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at numerous points in Kapoho. The channel overflow from July 9-10 created a new lobe that reached the ocean over the past day, destroying Ahalanui Park and the nearby charter school.

Impressive columns like these form along the margins of ice-confined lava flows but usually are eroded off the sides due to continued glacial movement after an eruption ceases. Columns are better preserved at the ends of the flows (this photo) where they are protected somewhat from the ice.

Extending approximately 75 miles north to south and 27 miles east to west, Newberry Volcano and its broad apron of lavas (light yellow shaded area) cover a total area of almost 1,200 square miles, making it the largest volcano of the Cascades volcanic chain. Its lavas stretch north beyond Smith Rock State Park, and south almost to Fort Rock State Natural Area.

The orange layer just below geologist's hiking pole is the Mazama ash (about 7700 ybp). Below that are glacial deposits. Above the Mazama is about a meter consisting mostly of fine-grained tephras from Glacier Peak, capped by soil and plants. That the tephras sit directly on top of the Mazama indicates that "Dusty" eruptions commenced about 7,000 years ago.
