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.

Example of a rip current experiment. Colors show bathymetry and arrows show velocity vectors after 1 h of model simulation. Similar to results in Kumar and others, 2012.

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.
