Project 2515 sy: Dating OLLIN (DatOI)

OLLIN is related to Aztec beliefs regarding earthquakes.

Abstract

The DatOI project aims to enhance the skills of developing country students and researchers from Latin America in the use of cosmogenic and palaeo-dosimetric dating on faulted markers. In addition, it also aims to communicate with seismic hazard modellers from Latin America about the uncertainties behind the dating and thus slip rates that they use and need.

The core achievement was the successful organization and execution of the “DatOl: Training School in Dating Methods for Active Tectonics”, held from 8 to 12 September 2025 at the Universidad Regional Amazónica Ikiam in Tena, Ecuador. The school was implemented as the official annual meeting of the UNESCO/IUGS-IGCP 669 “OLLIN” project, ensuring a wide regional impact.

The event directly trained 44 on-site participants (plus approximately 30 online attendees) from seven Latin American countries (Ecuador, Colombia, Peru, Venezuela, Chile, Mexico, Argentina), with a strong focus on Early Career Researchers (ECRs) and scientists from developing countries. The €7,000 grant was pivotal in covering critical costs, primarily supporting the participation of SS, ECRs and DCRs, in full compliance with INQUA’s guidelines. All planned objectives were met, significantly strengthening regional capacities in Quaternary dating methods for seismic hazard assessment.
