Wrong content There was a mistake in Supplementary Table S2 as published. Two volumes for SP and D2 have been reported incorrectly. The corrected Supplementary Table S2 The original version of this article has been updated. Wrong contentIn the abstract, the total volume was reported incorrectly in the result section. The sentence was displayed as "During 25 days, a dike propagated southward for 36 km, intruding a total of ∼0.3 km 3 of mafic magma" This has been corrected to read: "During 25 days, a dike propagated southward for 36 km, intruding a total of ∼0.4 km 3 of mafic magma." The original version of this article has been updated. Adding/removing text In the Introduction, the total volume was reported incorrectly. The sentence was displayed as "The event lasted 25 days, during which the intrusion mobilized ∼0.33 km 3 of magma and multiple magma bodies formed at various crustal levels.A correction has been made to the section Introduction: ""The event lasted 25 days, during which the intrusion mobilized ∼0.4 km 3 of magma and multiple magma bodies formed at various crustal levels."In the modelling, a volume was reported incorrectly. The sentence was displayed as "The sill deflated with a rate of ∼5.5 cm/yr corresponding to a total volume of drained magma of ∼0.3 km 3 from 2018 to June 2025".A correction has been made to the section 4.1 Pre-diking modelling: January 2018-June 2025: "The sill deflated with a rate of ∼5.5 cm/yr corresponding to a total volume 0.015 km 3 of drained magma from 2018 to June 2025 (Figure 3D; Supplementary Table S2)."In the modelling, a volume was reported incorrectly. The sentence was displayed as "The two dike segments have a distributed opening of up to ∼2 m, corresponding to a volume of intruded magma of ∼0.21 km 3 ,…".A correction has been made to the section 4.2 Co-diking modelling: July-August 2025: "The two dike segments have a distributed opening of up to ∼2 m, corresponding to a volume of intruded magma of ∼0.063 km 3 ,…"In the discussion, three volumes were reported incorrectly. The three sentences were displayed as: "Our models indicate that ∼0.21 km3 intruded the southern segments against 0.021 km 3 of magma drained from the NC dike.", "The dike stopped ∼9 km north of the Afrera town and opened up to ∼4 m (Figure 6B) with the volume of the intrusion being ∼0.33 km 3 of magma (Supplementary Table S2), "The total volume of magma intruded during the 2025 dike intrusion is ∼0.33 km 3 …".A corrections have been made to the section Discussion:" "Our models indicate that ∼0.063 km 3 intruded the southern segments against 0.021 km 3 of magma drained from the NC dike.", "The dike stopped ∼9 km north of the Afrera town and opened up to ∼4 m (Figure 6B) with the volume of the intrusion being ∼0.24 km 3 of magma (Supplementary Table S2).", "The total volume of magma intruded during the 2025 dike intrusion is ∼0.4 km 3 ,…"In the conclusion, a volume was reported incorrectly. The sentence was displayed as "The intrusion of 0.33 km 3 of basaltic magma was fed by a contracting dike below the NC and probably by a deeper sill at a depth of ∼7 km." A correction has been made to the section Conclusion: "The intrusion of 0.4 km3 of basaltic magma was fed by a contracting dike below the NC and probably by a deeper sill at a depth of ∼7 km."The original version of this article has been updated.
