The recent version of the global heat flow database contains about 91,182 data points from 1,586 publications (54,553 from the continental domain and 36,629 from the oceanic domain; status: release 2024; 04/2024). The admission of recent data is in progress - the next update is expected for summer 2025, as the second intermediate result of the data assessment project.
Quality: The database is currently under intense revision. The on-going reassessment of structure and quality of the database is supported and driven by the heat-flow community. Learn more about this process. The 2024 compilation, for the first time, contains quality score evaluations according to the IHFC quality codes. A detailed documentation is published here: doi: 10.1016/j.tecto.2023.229976. With the 2024 release, 49 % of data were re-assessed. For the remaining one, data are still missing for a reliable quality evauation. For these, users are still advised to consult the original references and to come to their own conclusion regarding the quality of the data.
