December 4, 2022 — Mauna Loa Fissure 3 Lava Channel

Detailed Description

Aerial image of the fissure 3 lava channel where it is braided, high on the Northeast flank of Mauna Loa. In this section of the channel, Hawaiian Volcano Observatory geologists observed several areas where lava overflowed from the channel, in one case due to a channel blockage downslope. Geologists also noticed large lava boats (up to 5 m or 16 feet) being transported down this section of the lava channel. USGS photo by H. Dietterich.
