Volcanic rift zone reorganization and massive underground magma chambers are required to solve the mystery of Mauna Loa’s Ninole Hills. Mauna Loa’s lava flows repave 90% of the surface every 4,000 yrs, finding 100,000 yr old rocks is a geological detective sleuthing game.

Dr. Jeffrey Zurek (P.Geo) marks the 10 yrs of his research in Geophysical Research Letters by diving into the geophysics of Hawaii. Using high-precision Bouguer gravity mapping, he reveals how catastrophic mass wasting events can knock a volcanic rift zone off its axis, preserving ancient topography and reshaping the evolution of basaltic island volcanism.
