A helicopter overflight on September 30, 2021, at approximately 7:30 a.m. HST allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. This thermal map shows the extent of the new lava lake within Halema‘uma‘u. 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. The dimensions of the new lava lake are 980 m (1070 yd) E-W axis and 710 m (780 yd) in N-S axis. The estimated area of the lake is about 52 hectares (127 acres). USGS map by M. Patrick.
