Maps

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. Small hotspots are also present on the walls of Halema‘uma‘u due to fumaroles.

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. The water lake has a surface area of approximately 25,000 square meters (6.2 acres), which is more than double the area measured in late December, when it was 11,000 square meters (2.7 acres).

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 geologic map.

The December 18, 2019, 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.

This preliminary thermal map shows relative surface temperatures across Kīlauea's 2018 lower East Rift Zone lava flow field.

This thermal map was constructed from 1008 images collected by a thermal camera during a helicopter overflight on August 22, 2019.

This thermal map, which was constructed by merging about 1300 images from a morning helicopter overflight on April 8, shows the distribution of some prominent thermal features in Kīlauea's summit caldera. 

Data depicted on this preliminary map of Kīlauea lower East Rift Zone lava flow thicknesses are subject to change.

This thermal map shows the fissure system and lava flows as of 6 am on Wednesday, August 15.
