Detailed Description
This zoomed-in view of the erupting western fissure in Halema‘uma‘u shows lava fountaining activity on the morning of October 4, 2021. The fountains have built a C-shaped spatter rampart around their source, which is now submerged in the rising lava lake. Using a laser rangefinder, HVO field crews measured the spatter rampart to be standing 20 m (66 ft) above the surrounding lava lake surface. USGS photo by M. Zoeller.
