Zone 7 - Younger part of Mauna Kea volcano. 20% of this area was covered by lava in the past 10,000 years. Zone 8 - Remaining part of Mauna Kea. Only a few percents of this area has been covered by lava in the past 10,000 years. Zone 9 - Kohala Volcano, which last erupted over 60,000 years ago.

In the lava-flow hazard mapping used by the USGS for the Island of Hawaiʻi, Lava Zone 8 is classified as one of the least hazardous areas on the island. This zone consists of the remaining parts of the Mauna Kea volcano, which is considered "dormant." According to the Hawaii County Planning Department, only a few percent of the land area in Zone 8 has been covered by lava flows in the last 10,000 years. For context, the USGS scale runs from Zone 1 (most hazardous, like the active rift zones of Kīlauea) to Zone 9 (least hazardous, like the Kohala volcano which hasn't erupted in 60,000 years). In Zone 8, the risk of a new eruption is extremely low, and the topography largely protects the area from flows originating from the more active Mauna Loa. Because of this high safety rating, homeowners and developers in Zone 8 typically find it much easier and cheaper to obtain property insurance and financing compared to those in Zones 1 or 2. This zone includes much of the North and South Kona districts that are sheltered from recent volcanic activity, making it a relatively stable and secure location for long-term residency and infrastructure on the Big Island.
