Lua Manu Crater is approximately 330 ft. (100 meters) in diameter and 125 ft. (38 meters) deep and was formed about 200 years ago. During the 1974 eruption of Keanakāko‘i, a fissure opened east of the forested Lua Manu Crater. The lava flow entered into the crater filling it with about 50 feet (15m) of lava, however about two-thirds of this lava later drained back into a fissure that cut its east crater wall. The "high lava mark" is still visible on the crater wall. This lava flow also crossed the Chain of Craters Road. Lua Manu Crater is generally considered to be the uppermost crater along the Chain of Craters in the upper east rift zone. Lua Manu Crater was formed when lava drained from the lava chamber beneath the surface, creating a void. This void caused the surface to collapse. The crater rim has no tephra (cinder, ash) deposits on the rim, thus indicating that there was no eruption or explosive event in its forming. It's located at mile 0.5 (0.8 km) since the beginning of Chain of Craters Road. Source: NPS
