Photographs from a Great-Horned Owl and Eurasian Collared-Dove found dead in a residential yard in Utah, U.S. (A) The owl had singeing of the rictal bristles on the right side of the face (inset), swollen right eyelids, and a cloudy and thickened right cornea.

The December 18 overflight provided updated thermal images of Kīlauea summit, covering the caldera floor and showing the warm surface of the water pond in Halema‘uma‘u crater. A band of warm temperatures persists along the new cliff formed during the 2018 subsidence.

The December 18 overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water pond in Halema‘uma‘u crater. The label "downdropped block" shows the large portion of the caldera floor that subsided, along with the Halema‘uma‘u region, during the 2018 eruption.

USGS Hawaiian Volcano Observatory scientists Frank Younger and Patricia Nadeau talk about sampling the water at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano. The water appeared in July 2019 and has steadily risen since then.

Photos taken two weeks apart show the rise of water in Halema‘uma‘u. A white arrow denotes a large rock along the edge of the lake for comparing water levels in the two images. The water continues to rise at a rate of approximately 15 cm (6 in) per day. USGS photos by M. Patrick.

The 1880-1881 eruption of Mauna Loa produced lava flows that came within 1.7 km (1.1 mi) of the Hilo Bay shoreline. This painting by Charles Furneaux, "Night View 1880–1881, Eruption from Hilo Bay," illustrates the first two flows as they would have been in November 1880. In reality, however, both flows would not have been visible from this vantage.
