About this map

The Southwest Rift Zone dominates this section of the island of Hawaii, where the terrain is a complex record of volcanic activity. This area within Kahuku and Keapohina is defined by a succession of major eruptions, including the extensive Alika Lava Flow of 1919, the Lava Flow of 1926, and the massive Honokua Lava Flow of 1950. The namesake Alika Cone stands as a prominent landmark amidst these intersecting flows.

A rare human element in this active landscape is the Hawaiian Old Trail, which crosses the southeastern portion of the map. The map reflects the state of the terrain as photo-inspected in the mid-1990s, capturing how more recent events like the 1950 flow overlapped and reshaped older features such as the Alala Lava Flow. This document serves as a geological timeline, documenting the shifting surface of the Southwest Rift Zone over decades of the twentieth century.
