Session: Earth’s Transient Behavior Through Synthesis of Observational, Laboratory, and Theoretical Approaches#
“Earth’s mechanical response to stress can be viewed as a combination of two end-member behaviors (purely elastic, and steady-state viscous) with a third: a time-varying transient response. This transient behavior is essential for accurately capturing phenomena on “broadband” timescales from 10-1 to 1012 s, including seismic attenuation, solid-Earth tides, the seismic cycle, hydrological loading, and post-glacial rebound. In this session we explore a combination of geophysical observations, laboratory observations, and theoretical frameworks that span broad time- and length-scales, with the goal of identifying relationships that explain and predict Earth’s broadband behavior. We invite contributions from the seismology, geodesy, rock mechanics, and geodynamics communities (relevant to any space and timescale!) which shed light on understanding Earth’s transient mechanical behavior.”
