Photo and Video Chronology – Kīlauea – July 19, 2022

By Hawaiian Volcano Observatory July 20, 2022

The Hawaiian Volcano Observatory conducted a geology monitoring overflight of Kīlauea summit on July 19, 2022.

An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Lava activity is confined within Halema‘uma‘u crater, in the closed area of Hawai‘i Volcanoes National Park.

Hawaiian Volcano Observatory geologists captured this view of the caldera at Kīlauea summit during an overflight the morning of July 19, 2022. The active lava lake is visible within Halema‘uma‘u crater, the floor of which continues to slowly rise as the eruption continues. The former Hawaiian Volcano Observatory buildings can be seen in the lower center portion of the photo.

Aerial view of the western portion of Halema‘uma‘u crater at the summit of Kīlauea, taken during a Hawaiian Volcano Observatory geology monitoring overflight on July 19, 2022. The floor of Halema‘uma‘u crater continues to rise as the eruption at the summit of Kīlauea continues, with lava flows encroaching on the down-dropped block located to the southwest of Halema‘uma‘u (center left part of this image). Mauna Loa volcano is visible in the background. USGS image by K. Mulliken.

During a Hawaiian Volcano Observatory Kīlauea summit monitoring overflight on July 19, 2022, lava was oozing out the northern edge of Halema‘uma‘u crater floor. Incandescent lava is visible in this area, near the bottom center of this image, where lava is slowly encroaching on the large down-dropped block that formed during the 2018 caldera collapse.

A closer view of active lava on the north margin of Halema‘uma‘u crater, at Kīlauea summit. This small pad of lava oozed out from the crater floor along the north boundary of the crater, near where the down-dropped block to the east slopes down towards Halema‘uma‘u crater. USGS image by K. Mulliken.

An aerial image of the western portion of Halema‘uma‘u crater at the summit of Kīlauea. The active lava lake within the western portion of Halema‘uma‘u crater is visible in approximately the center of the image, and lava spattering is visible along the eastern edge of the lake. This view is from the north side of the crater, and looks generally to the south.  USGS image by K. Mulliken.

Telephoto aerial image of a hornito on the surface of the eastern part of Halema‘uma‘u crater floor at the summit of Kīlauea. In the foreground, Hawaiian Volcano Observatory monitoring equipment on the eastern rim of Halema‘uma‘u crater gives a sense of scale. Several hornitos, each several tens of feet tall, rise from the floor of Halema‘uma‘u crater. These hornitos are small spatter cones that are supplied with lava from beneath the solidified surface crust that forms the floor of Halema‘uma‘u crater. USGS image by J. Chang.

In the middle of the image, the island that formed during the early phases of the eruption that began the evening of December 20, 2020, is visible; behind it, the west vent area is visible as a series of jagged peaks emitting volcanic gas. On July 18, a sulfur dioxide (SO2) emission rate of approximately 1,700 tonnes per day (t/d) was measured. USGS image by J. Chang.
