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.
Kīlauea Volcano — Overflows
Overflows from the perched lava channel are seen as incandescent (glowing) fingers moving down the sides of the channel (left side of photo). Fissure 8

Kīlauea Volcano —
Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west. Halema‘uma‘u crater is in upper

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

Kīlauea Volcano — Lava Channel Branches Off
Southward facing view of the point at which the fissure 8 lava channel bifurcates.
Kīlauea Volcano — 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.
Kīlauea Volcano — Ocean Entry
North facing view of the 1 km (0.6 mi) long ocean entry with multiple lobes of lava flowing into the sea.
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

Lava breakouts continue on the coastal plain and on the delta
The U.S. Geological Survey has produced a documentary, "Kīlauea Summit Eruption–Lava Returns to Halema‘uma‘u," to tell the story of the eruption, and to share imagery of the inaccessible lava lake with the public.

Coastal breakouts put on a show
In today's age of aerial photography, satellites, and drones, bird's-eye views of geologic features are taken for granted. A century ago, such depictions posed enormous challenges.
Thirty-seven years after the May 18, 1980, eruption of Mount St. Helens, Washington, scientists, engineers, land managers, and Federal, State, and County officials are still grappling with a challenge created by the eruption—how to prevent potentially massive downstream flooding by the release of water from Spirit Lake, located at the base of the volcano.
