Views of the 2018 lower East Rift Zone lava flow field along Highway 132
HVO geologists visited the lower East Rift Zone lava flow field this past week to make measurements and observations, to better understand and reconstruct the dynamics of the Fissure 8 lava flow. This photo shows the channel wall in the braided channel region of the flow.

A Legendary part of the Wailuku River is again revealed
View of the recently cleared Boiling Pots on the Wailuku River in Hilo. The pots, each about 15 m (50 ft) in diameter, are eroded into a 10,000 year old Mauna Loa lava flow. When the water is low, the river does not flow over some of the pot rims but it continues to flow through them. USGS photo.

Geologists from Montana State University study an outcrop of diorite
Geologists from Montana State University study an outcrop of diorite (a silicic igneous rock that cooled slowly beneath the ground). An outcrop of this size is important because it is easier to see any structural relations along with rock composition.

In the eastern portion of the lake, the dark brown zone had a slightly mottled appearance, but this pattern was transient and gone within about ten minutes.

Station PR05 is part of the Mount Rainier lahar detection network.
USGS-Cascades Volcano Observatory geophysicist Rebecca Kramer works on station PR05, which is part of the Mount Rainier lahar detection network (Mount Rainier is pictured in the distance). The purpose of the site visit was to upgrade the power system and deploy infrasound equipment.

Continued slow rise of water in Halema‘uma‘u
The water lake within Halema‘uma‘u crater, at the summit of Kīlauea, continues to slowly rise, with no significant changes in recent weeks. USGS photo by M. Patrick.

May 29, 2020—Updated aerial map of Kīlauea summit
The May 29 overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water lake in Halema‘uma‘u crater.

May 29, 2020—Thermal map of Kīlauea summit
The May 29 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water lake in Halema‘uma‘u crater. No significant changes were observed in the surface temperature of Kīlauea's summit crater lake.

During today's overflight of Kīlauea summit, both thermal and visual camera
During today's overflight of Kīlauea summit, both thermal and visual cameras were used to characterize activity. Comparing thermal (left) to visual (right) images of nearly the same view, you can see that the growing crater lake at Kīlauea's summit remains hot.

Comparing Kīlauea's summit before and after the 2018 collapse
This series of maps compares aerial imagery collected prior to Kīlauea's 2018 summit collapse and the "Geologic Map of the Summit Region of Kīlauea Volcano, Hawaii" (Dutton and others, 2007; Neal and others, 2003)—created before Kīlauea's 2018 summit collapse—with aerial imagery collected after the 2018 summit collapse and a preliminary update to Kīlauea's summit ge
