Is the Hawai'i lava-flow hazard zone map still accurate?

Yes, the Map Showing Lava-Flow Hazards Zones on Hawai'i Island is still accurate. It was most recently revised in 1992.

The map is intended to communicate long-term lava-flow hazards, rather than short-term hazards, which can change daily during periods of eruptive activity.

Hazard assessments are based on the assumption that future eruptions will be similar to those in the past. For the past 200 years, eruptions of Kīlauea and Mauna Loa have occurred at their summits and/or along one of their rift zones—and future eruptions on these volcanoes are likely to occur in the same areas.
