This map shows lava flow and tephra accumulation at the summit of Kīlauea volcano associated with episode 42 of the ongoing eruption in Halemaʻumaʻu that started on December 23, 2024, using data recorded by the Italian Space Agency's (ASI) COSMO-SkyMed Second Generation satellite constellation.

This map shows recent deformation at Kīlauea, over the timeframe of February 10–16, 2026. Data were acquired by the European Space Agency's Sentinel-1A/C satellites. Each color cycle represents 2.8 cm (1.1 in) of ground movement in the direction between the satellite and the ground (range change).

This map shows the tephra fall associated with episode 41 of Kīlauea's episodic summit eruption, on January 24, 2026. Tephra is a generic word for any material erupted by a volcano that travels through the air before landing on the ground.

This map depicts the locations of approximately 300 earthquakes that have occurred between January 12 and 22, 2026, in the summit region of Kīlauea volcano. Most earthquakes have been smaller than magnitude-2, with locations broadly distributed beneath Halemaʻumaʻu and the south caldera region of Kīlauea summit.

The bedrock geology of the 7.5-minute Eagle Lake quadrangle, Essex County, New York, consists of deformed and metamorphosed Mesoproterozoic gneisses of the Adirondack Highlands unconformably overlain by weakly deformed lower Paleozoic sedimentary rocks of the Champlain Valley. The Mesoproterozoic rocks occur on the eastern edge of the Adirondack Highlands and represent an extension of...

This thermal map of the summit of Kīlauea was made from images collected during a January 16 overflight, just four days after the episode 40 lava fountaining on January 12.
