Isostasy and Flexure of the Lithosphere
Perspective image (looking towards the west) of the free-air gravity anomaly along the Hawaiian-Emperor seamount chain in the northwest Pacific Ocean. Hawaii Island is in the foreground. The gravity expression of the flexural moats (blue/purple region) and bulges (yellow-green region) that flank the islands and seamounts along the chain are clearly visible in the image.
