Overflows from the perched lava pond within west pit, a small crater adjacent to the main Pu‘u ‘Ō‘ō crater on Kīlauea Volcano's East Rift Zone, continue to build up the levees around the pond. The rising level of the perched lava pond during the past month is a sign of the increasing pressure within the magma system beneath Pu‘u ‘Ō‘ō.

USGS researchers drill a research well located on the south side of U.S. 90, 7.1 miles east of Brackettville, Texas. This core was drilled by USGS during field work for an oil and gas assessment for the Eagle Ford of the Gulf Coast Basins. Cores like these provide information on the various rock layers, such as their make-up, their age, etc.
