Four scientists are busy reviewing seismic data, checking maps, and uploading activity updates in the USGS Volcano Hazards Program's Volcano Observatory operations room from the Menlo Park, California USGS campus.

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.

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.

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.

Anti-fouling treatment is applied to a sensor on a platform about to be deployed off Fire Island, NY in 2012.  The data collected is part of a study of the coastal processes that mobilize and transport sediment in the region

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.

The late Jerry P. Eaton came to the Hawaiian Volcano Observatory in 1953 and served as HVO's Scientist-in-Charge in 1956-1958 and again in 1960-61.

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.

Photograph showing outcrop of eroded and dissected extinct volcano located adjacent to the Frio River and east of the city of Uvalde in Uvalde County, Texas. Basalt is remnant of volcanic neck, and adjacent to the basalt is pyroclastic material ranging from fine-grained material to volcanic bombs, which formed the slope of the volcano.

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.
