Graphite schist from the Roanoke Rapids terrane in southeastern Virginia. Economic deposits of this critical mineral may exist in this relatively unexplored region, which has not been adequately mapped at scales larger than 1:250,000.

Staurolite weathering out of schist along the eastern edge of the Roanoke Rapids terrane in southeastern Virginia. Is this greenschist-facies schist part of the suprastructural Roanoke Rapids terrane, or part of a heretofore undefined higher-grade infrastructural terrane to the east?

Throughout Hawaii, fishponds are considered by their local communities as important cultural touchstones, a source of local, sustainably produced food, and an important component to the development of community-based management for nearshore fisheries.

Hawaiian fishponds are important cultural and economic resources for native Hawaiians as they are an important component of a sophisticated, integrated food production system. However, changing demographics and systems of land ownership result in declines in the use and upkeep of Hawaiian fishponds throughout the 19th century.

During the first two weeks of Kīlauea Volcano's 2018 lower East Rift Zone eruption, fissures were characterized by low eruption rates and small flows. This was because the erupted lava originated from pockets of cooler, less fluid magma stored in the rift zone.

An Unmanned Aircraft Systems overflight of fissure 8 on Saturday afternoon (Sept. 1, 2018) showed incandescence within the cinder cone, with reports that lava had covered the 65x15 m (210x45 ft) crater floor by evening.

An Unmanned Aircraft Systems overflight on Sunday afternoon (Sept. 2, 2018) showed that lava remained active within the fissure 8 cone.

Early this morning, the Unmanned Aircraft Systems team was able to conduct a brief overflight of fissure 8 between passing rain showers, which resulted in abundant steaming on the flow field.

This UAS oblique image of fissure 8 shows that the new lava is mostly confined to the crater floor within the cone, although a small amount extended a short distance into the spillway. HVO geologists noted that the lava activity was at a low level, with the area of incandescence decreasing to almost zero over the course of the afternoon.

This view across the summit caldera shows ground cracks (center) just north of Halema‘uma‘u. Rockfalls within the crater and along the caldera walls continue to stir up dust that can be seen here rising above the caldera rim.
