Detailed Description

Map of hazard zones for ground fractures and "small-scale" subsidence for the Island of Hawai‘i. Subsidence and fracturing events are frequent in zone 1, which covers the summit and rift zones of Kīlauea and Mauna Loa volcanoes, but are somewhat less frequent in zone 2, on the south flank of Kīlauea. Zone 3 includes areas around the Kealakekua and Ka‘ōiki Fault Systems on Mauna Loa. Zone 4 includes the remainder of the island. (include link to PP 1801 in caption).
