Isostatic Rebound
Project Description

Isostatic rebound occurs when a load is imposed on or removed from the lithosphere (the rigid, outermost shell of our planet). The surface tends to rise or sink as the lithosphere rises or sinks in the highly viscous, mechanically weak region of the upper mantle of the Earth (also known as the asthenosphere). Loads may consist of large lakes, oceans, ice, sediment, and volcanoes. The rising or sinking of the lithosphere will continue until isostatic equilibrium is reached.

This is a simplified illustration of isostatic rebound near Amazon River. It was produced in collaboration with Dr. Mike Bevis et al., Ohio State University.
