December 7, 2022 — Mauna Loa Northeast Rift Zone eruption fissure 3 lava flow thermal map

December 7, 2022
Color map of lava flow temperature
A helicopter overflight on December 7, 2022, allowed for aerial visual and thermal imagery to be collected of the Northeast Rift Zone eruption of Mauna Loa. This map only shows activity from Fissure 3 on the Northeast Rift Zone, which is feeding a lava flow to the north. A significant breakout has removed lava from the channel about 2.8 mi (4.5 km) behind the tip of the main flow. 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.
