S032 - The Value of Macroseismic Intensity Data: from Earthquake Source Characterization to Ground Motion and Seismic Hazard Estimation and Testing

The value of macroseismic data, defined as the effects of earthquake shaking on people and the natural and built environment, commonly used to estimate numerical intensity values, is increasingly recognized by our community. Macroseismic data provide unique and invaluable information for many types of investigation, and several methods have been developed in recent years to fully exploit them, including an appreciation of both their limitations and value. This session welcomes contributions on both methodologies to analyze this kind of data and case histories, aiming to cover the widest possible range of their applications in the seismological and engineering practice.

A non-exclusive list of topics includes: investigating past earthquakes, characterizing their sources, compiling long-term catalogs, characterizing long-term seismicity for probabilistic seismic hazard assessment, estimating expected shaking levels through intensity attenuation models and relationships between ground motion parameters and macroseismic intensity, testing and retrospective evaluation of seismic hazard estimates and shaking scenarios.
