September 20, 2024 — Thermal map of eruption on Kīlauea East Rift Zone

A helicopter overflight on September 20, 2024, allowed for aerial visual and thermal imagery to be collected at the middle East Rift Zone eruption site on Kīlauea.  This thermal map shows that the eruption at Nāpau Crater had paused this morning, with no fountaining or active lava on the surface. Shortly after these morning thermal images were collected, a small portion of the fissure system briefly reactivated, but soon died out again. As of this afternoon, the eruption was again in a pause. 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.
