Color map of lava lake temperature

Detailed Description

A helicopter overflight on March 26, 2021, at approximately 8 a.m. HST allowed for aerial visual and thermal imagery to be collected of the eruption within Halema‘uma‘u crater at the summit of Kīlauea Volcano. Active surface lava is largely limited to the western side of the lake; the eastern portion of the lake has stagnated and is dominated by cooling, solidified crust. The scale of the thermal map ranges from blue to red, with blue colors indicative of cooler temperatures and red colors indicative of warmer temperatures. USGS map by B. Carr.
