pāhoehoe flow from the fissure eruption at the site of the Kupaiana...
Detailed Description
New pāhoehoe flows are overriding dark ‘A‘ā flows from Pu‘u ‘Ō‘ō, 3 km uprift (in background). The Pu‘u ‘Ō‘ō conduit failed on July 18, triggering fissure eruptions both up- and downrift of the cone. On July 20 (beginning of episode 48), the fissure at this site began to erupt, initiating 5.5 years of near-continuous effusion from the Kupaianaha vent. The high-fountaining episodes of Pu‘u ‘Ō‘ō were over.
