World Catalog of Earthquake Rotated Objects (EROs)

The World Catalog of Earthquake Rotated Objects (EROs) is composed of 2254 EROs originated during 213 earthquakes occurred between 1349 and 2018. The EROs Catalog is organized into two different datasets that report the most important parameters and informations about the source earthquakes and about the observed EROs, respectively. The seismic event dataset (Events - red stars) reports the parameters of earthquakes (magnitude, intensity, focal mechanism etc) from which EROs observations are used. The EROs dataset (Observations - yellow dots) lists several parameters and data (epicentral distance, type of object, sense of rotation etc) associated with each ERO observation. It also contains the complete reference list for each seismic event, including the citation associated with the EROs observations. When using data from the EROs Catalog please cite the following papers: Cucci L., A. Tertulliani and A.M Lombardi (2016).
