In Hawaii each section of the island is in a specific lava zone. When purchasing property or a home on the island of Hawaii the lava zone is important because in some areas home owners insurance cannot be had, in some areas the banks will not grant loans. If you are looking to buy in Hawaii make sure you do your homework and find out the facts on lava zones by checking with a local Hawaii Realtor (preferably me!)
Hazard Zones for Lava Flows on the Island of Hawai`i |
|||
|---|---|---|---|
|
Hazard zones from lava flows on the Island of Hawai`i are based chiefly on the location and frequency of historic and prehistoric eruptions and the topography of the volcanoes. Scientists have prepared a map that divides the five volcanoes of the Island of Hawai`i into zones that are ranked from 1 through 9 based on the relative likelihood of coverage by lava flows. |

| Zone | Percentage of area covered by lava since 1800 | Percentage of area covered by lava in last 750 years | Explanation |
| 1 | greater than 25 | greater than 65 | Includes the summits and rift zones of Kilauea and Mauna Loa where vents have been repeatedly active in historic time. |
| 2 | 15-25 | 25-75 | Areas adjacent to and downslope of active rift zones. |
| 3 | 1-5 | 15-75 | Areas gradationally less hazardous than Zone 2 because of greater distance from recently active vents and/or because the topography makes it less likely that flows will cover these areas. |
| 4 | about 5 | less than 15 | Includes all of Hualalai, where the frequency of eruptions is lower than on Kilauea and Mauna Loa. Flows typically cover large areas. |
| 5 | none | about 50 | Areas currently protected from lava flows by the topography of the volcano. |
| 6 | none | very little | Same as Zone 5. |
| 7 | none | none | 20 percent of this area covered by lava in the last 10,000 yrs. |
| 8 | none | none | Only a few percent of this area covered in the past 10,000 yrs. |
| 9 | none | none | No eruption in this area for the past 60,000 yrs. |
