Geometry of the Magma Chamber and Curie Point Depth Beneath Hawaii Island: Inferences From Magnetic and Gravity Data

This study used land gravity and airborne magnetic data to investigate the depth magmatic chamber map heat flow distribution beneath active volcanoes of Hawaii Island using Curie point (CPD) modeling. Obtaining some ground-based geophysical measurements was problematic due accessibility limitations; therefore, this available data. The CPD were bottom layer by calculating isotherm (540°C) Island. spectral peak method calculate depths shallow deep sources for entire island, calculated centroid method. A two-dimensional density model two Earth layers constructed forward modeling large plume dense intrusive material observed three adjacent Mauna Loa, Kea, Kilauea, small chambers found be located Kohala Hualalai volcanoes. Based on results, magma varied from 0.5 10 km, higher close volcanic eruption zones. current is informative cost effective world’s most areas.
