routine inspection of a UAS system prior to a flight

Two U.S. Geological Survey Unmanned Aircraft Systems (UAS) pilots perform a routine inspection of a UAS system prior to a flight at the summit of Kīlauea Volcano in June 2018. The UAS for this particular flight was outfitted with a multi-gas sensor to identify any new degassing sources within the collapsing summit caldera. All UAS flights inside Hawai‘i Volcanoes National

Kīlauea Volcano — Ocean Entry

View of the ocean entry (lower left) from this morning's overflight. Lava was entering the ocean across a broad area primarily on the north part of the lava delta. Upslope along the northern margin of the flow field, lava is still oozing from several points in the area of Kapoho Beach Lots. Fissure 8

Kīlauea Volcano — Fresh Lava at Kapoho Beach Lots

Near the coast, the northern margin of the lava flow field is still oozing fresh lava at several points in the area of Kapoho Beach Lots. Smoke marks locations where lava is burning vegetation.

Kīlauea Volcano — Kapoho Coastline Ocean Entries

Lava continues to enter the sea along the southern Kapoho coastline. Lava enters the ocean primarily through an open channel, but also along a 1-km (0.6 mi) wide area. Also visible in the image (center right) is an area at the northern margin of the flow field that is oozing fresh lava at several points in the area of Kapoho Beach Lots.

Kīlauea Volcano — Channel Overflow

A small overflow from the lava channel (left side of image) captured by an Unmanned Aircraft System (UAS). Small overflows on both sides of the channel occurred shortly after midnight in the uppermost part of channel. None of these overflows extended past the existing flow field.

October 26, 2017

Using detailed geologic mapping and modeling of how a fluid (in this case, lava) responds to surface topography, USGS-HVO constructed nine maps depicting 18 inundation zones on Mauna Loa. Each zone identifies a segment of the volcano that could erupt lava and send flows downslope.
