The original version of this article contained errors in the estimated magnitude of the Coulomb stress changes--caused by the removal of mass at a near-by cement quarry--on the faults associated with the November 11, 2019, Le Teil (southern France) earthquake. The errors derived from the use of incorrect values for the volumes of removed material in the stress computation, and led to an overestimate by almost one order of magnitude of the maximum Coulomb stress change that resulted from the quarrying activity on the faults that caused the earthquake. The estimated volumes, indicated in Table 4 of the Supplementary Information, were computed correctly, but then a wrong file was used in the stress calculation. By considering the correct volumes, the maximum Coulomb stress changes (?CFF) on the La Rouvière (LRf) and La Chade (LCf) faults that we had erroneously indicated as 1.10 MPa and 1.15 MPa are actually only 0.19 MPa and 0.18 MPa, respectively. They are therefore almost one order of magnitude smaller than the earthquake stress drop of 1.3 MPa. Based on the corrected values, we conclude that the quarry activity did not induce the 2019 Le Teil earthquake. The corrected Coulomb stress change estimates do support our conclusion that the earthquake was triggered by the mass removed from the quarry. However, based on the corrected Coulomb stress changes, we infer that the occurrence of the earthquake was hastened by only about 18,000 years, and not by about 110,000 years, as we had inferred from the erroneous values. We would like to warmly thank Chao Liang and Jean-Paul Ampuero, from Université C?te d'Azur (France), for bringing the mistake to our attention, by checking the coherence of the stress computation with the estimated volumes.

Abstract
The original version of this article contained errors in the estimated magnitude of the Coulomb stress changes--caused by the removal of mass at a near-by cement quarry--on the faults associated with the November 11, 2019, Le Teil (southern France) earthquake. The errors derived from the use of incorrect values for the volumes of removed material in the stress computation, and led to an overestimate by almost one order of magnitude of the maximum Coulomb stress change that resulted from the quarrying activity on the faults that caused the earthquake. The estimated volumes, indicated in Table 4 of the Supplementary Information, were computed correctly, but then a wrong file was used in the stress calculation. By considering the correct volumes, the maximum Coulomb stress changes (?CFF) on the La Rouvière (LRf) and La Chade (LCf) faults that we had erroneously indicated as 1.10 MPa and 1.15 MPa are actually only 0.19 MPa and 0.18 MPa, respectively. They are therefore almost one order of magnitude smaller than the earthquake stress drop of 1.3 MPa. Based on the corrected values, we conclude that the quarry activity did not induce the 2019 Le Teil earthquake. The corrected Coulomb stress change estimates do support our conclusion that the earthquake was triggered by the mass removed from the quarry. However, based on the corrected Coulomb stress changes, we infer that the occurrence of the earthquake was hastened by only about 18,000 years, and not by about 110,000 years, as we had inferred from the erroneous values. We would like to warmly thank Chao Liang and Jean-Paul Ampuero, from Université C?te d'Azur (France), for bringing the mistake to our attention, by checking the coherence of the stress computation with the estimated volumes.
