A helicopter overflight today (Dec. 22, 2020) at approximately ~11:30 AM HST allowed for aerial visual and thermal imagery to be collected of the new eruption within Halema'uma'u crater at the summit of Kīlauea Volcano. This preliminary thermal map shows that the new lava lake is 690 m (yd) E-W axis and 410 m (yd) in N-S axis. The lake area is about 22 hectares (54 acres). USGS map by M. Patrick.
