Color map of lava lake temperature

A helicopter overflight on January 5, 2021, at approximately 8:30 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. The dimensions of the lava lake are 760 m (831 yd) E-W axis and 470 m (514 yd) in N-S axis. The most recent estimate of lake area is about 28 hectares (69 acres). 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 M. Patrick.
