Lava Flow Hazard Assessment, as of August 2007, for Kīlauea East Rift Zone Eruptions, Hawai‘i Island

By Jim Kauahikaua

Looking back toward Pu‘u ‘Ō‘ō, a perched lava pond was forming over fissure D in this July 23, 2007 photo. Pu‘u Kahauale‘a is the vegetated cone behind the perched pond (from figure 4)Summary

The most recent episode in the ongoing Pu‘ ‘Ō‘ō—Kupaianaha eruption of Kīlauea Volcano is currently producing lava flows north of the east rift zone. Although they pose no immediate threat to communities, changes in flow behavior could conceivably cause future flows to advance downrift and impact communities thus far unaffected. This report reviews lava flow hazards in the Puna District and discusses the potential hazards posed by the recent change in activity. Members of the public are advised to increase their general awareness of these hazards and stay up-to-date on current conditions.
