Hawaiian fishponds were important cultural and economic resources for native Hawaiians as they were an important component of a sophisticated, integrated food production system. However, changing demographics and systems of land ownership resulted in a decline 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.

The Landsat archive has added its 8 millionth scene. This stunning image was captured by Landsat 8 on July 28, 2018. It shows the coastline of Nordaustlandet, the second-largest island in Norway’s Svalbard archipelago.

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.

A group of feral pigs leaves the forest and approaches the photographer at the side of the road. Many parts of Hilo and Hawaii Island are experiencing increased interaction with feral wildlife.

Glaucous-winged Gulls capitalize upon a disturbance at the Gull Island colony in 2018 to grab eggs abandoned by breeding Common Murres. One lone Common Murre continues incubation despite the rest of the colony flushing.

HVO field crews carefully traverse the uneven surface of the channel levee (left of image) to make measurements of the fissure 8 lava channel. The lava is slowly cooling and contracting but the area remains warm (note the steam rising). The view is to the east, with Puu Honuaula in the distance (right of image).

An Unmanned Aircraft Systems overflight of fissure 8 on August 21, 2018, showed no incandescence within the cinder cone. Minor amounts of gases, primarily steam, rose from the north wall of the cinder cone and from areas along the lower East Rift Zone. The interior walls of the fissure 8 cone and lava channel are slumping downward and inward.

The south edge of the lava flow showed no incandescence this morning and remained less than 0.1 miles from the Pohoiki boat ramp in Isaac Hale Park. The main ocean entry area was still in the Ahalanui area.

Void spaces within the cooled lava channel and along the channel margins create hazardous conditions on the fissure 8 flow field. Here, part of the void is visible, but a fragile veneer of lava hides other parts of it (upper right).
