Figure 9.64.
WSW-ENE profiles across the west coast of the island of Hawaii and
the summit of Mauna Loa volcano. (a) The P-wave velocity structure determined
from seismic refraction experiments. The vertical exaggeration is 4 : 1. (b) Bouguer
gravity anomaly onshore, free-air gravity anomaly offshore. Dots, measured
anomalies; solid line, a matching anomaly computed from the density model in (c).
(c) The density structure based on the seismic-velocity structure shown in (a). The
vertical exaggeration is 2 : 1. (d) A schematic geological structure based on the
velocity and density models. The central magma conduit and the summit magma
chamber are shown solid black. True scale. (From Hill and Zucca (1987).)
