Kīlauea Summit UAS footage shows an ever growing Halema‘uma‘u Crater

Kīlauea Summit UAS footage shows an ever growing Halema‘uma‘u Crate...

A UAS mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit. The deepest part of Halema‘uma‘u is now over 400 m (1300 ft) below the crater rim. The obvious flat surface within the crater is the former Halema‘uma‘u crater floor, which has slumped downward as a nearly intact block.

This video was taken from a UAS (Unoccupied Aircraft Systems). Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. The overflights collect visual information on what is happening at this rapidly changing eruption site. Scientists examine the footage in detail to understand how the expanding collapse area is evolving, the extent of tephra fall, and other surface changes. This information is used to assess hazards at Kīlauea's summit , which are shared with the National Park Service and emergency managers.

Timelapse of Kīlauea's Lower East Rift Zone eruption lava flow maps

A new video shows a timelapse of the lava flows erupted in Kīlauea's Lower East Rift Zone between May 16 and June 25. It was created from the GIS files produced for the Hawaiian Volcano Observatory's map updates, which may be downloaded. Pre-2018 lava flows are shown with purple outlines, current flows in red, and the basemap is the USGS National Map. Lava flow layers are displayed at 50% transparency to allow features underneath them to remain visible, so their appearance may vary.

Lava entering the ocean causing laze plumes

Lava from fissure 8 is entering the sea this morning on the southern portion of the flow front primarily through the open channel, but also along this 1 km (0.6 mi) wide area with multiple laze plumes from smaller oozing lobes.

Remobilized volcanic ash plume rises from Ka‘ū Desert

Kīlauea Volcano — Remobilized Ash Plume

Recent explosive events haven't produced significant ash plumes from the summit, but downwind communities may still experience ashfall when previously erupted ash is remobilized. On authorized permission from Hawai‘i Volcanoes National Park, our Unmanned Aircraft Systems crew is conducting gas measurements at Pu‘u ‘Ō‘ō. They snapped this photograph from Chain of Craters Road - a plume of remobilized ash is clearly visible along the horizon. It is rising from the Ka‘ū Desert and blowing to the southwest.
