The T4 working catalogue before 1964 of the SARA (South American Risk Assessment) project

This repository contains a homogeneous earthquake catalogue in Mw for the pre-1964 period, documenting 2,556 earthquakes that occurred in South America. It was compiled as part of the T4 catalogue of the SARA project (South America Risk Assessment). The moment magnitude (Mw) for these events was determined from various sources, including ISC-GEM (Storchak et al., 2013), CERESIS (1995), and national seismic databases. The dataset is provided in CSV format and includes details such as the source code, event date (Year, Month, Day, Hour, Minute, Second), maximum intensity, number of known Macroseismic Data Points (MDPs), epicentral coordinates (Latitude, Longitude), hypocentral depth (km), Mw and its associated uncertainty, and the method used for Mw determination.
