Will the Hawai'i lava-flow hazard zone map be revised?

The Map Showing Lava-Flow Hazard Zones on Hawai'i Island reflects long-term lava-flow hazards based on geologic data: the behavior of Hawaiian volcanoes over decades to centuries, the distribution and ages of lava flows and volcanic vents, the structure of the volcano, and topography. The map will not be revised until the geologic processes/structures/topography of the volcanoes change enough to warrant an update.
