Maui Zone 2 - Areas that are mainly downslope of the peak of
Haleakalā. These areas have mostly been covered in lava in at least the last 13,000 years or are expected to be near possible rift sites. This zone is similar to Zone 4 on the island of
125:. First prepared in 1974 by Donal Mullineaux and Donald Peterson of the USGS and revised in 1992 for the Island of Hawaiʻi, the maps outline the qualitative hazard posed by lava flows based on the history of lava flow activity on each of the five
156:
Zone 2 - Areas adjacent to and downslope of zone 1. 15-25% of zone 2 has been covered by lava since 1800, and 25-75% has been covered within the past 750 years. Relative hazard within zone 2 decreases gradually as one moves away from zone
214:
Maui Zone 3 - These are areas protected by topology caused by previous lava flows in the last 40,000 years. This makes it most similar to Zone 6 on the island of Hawaiʻi, which is also protected by topology and a similar danger
160:
Zone 3 - Areas less hazardous than zone 2 because of greater distance from recently active vents and (or) because of topography. 1-5% of zone 3 has been covered since 1800, and 15-75% has been covered within the past 750
207:
Maui Zone 1 - Includes the crater of
Haleakalā and some rift zones, mainly areas that have experienced major eruptions in the last 1500 years. This is similar to Zone 3 on the island of Hawaiʻi.
168:, where the frequency of eruptions is lower than that for Kilauea or Mauna Loa. Lava coverage is proportionally smaller, about 5% since 1800, and less than 15% within the past 750 years.
218:
Maui Zone 4 - Functionally has no danger from eruption havening not been inundated with lava for at least 100,000 years. This makes it most similar to a Zone 9 on the island of Hawaiʻi.
