June 12, 2023 — Kīlauea summit thermal map compilation

This compilation shows thermal maps of the initial days of the ongoing eruption in Halema‘uma‘u crater, at the summit of Kīlauea. The high initial eruption rates in the opening day of the eruption supplied numerous lava fountains that covered the entire crater floor with new lava. Over the next few days the eruption rates declined and stabilized, supplying a smaller lava lake area in the southwestern portion of the crater. 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.
