a, Eastward displacement recorded at KBT (blue) and RBV (orange) GNSS stations. b,c, Distance to crater (b) and magnitude (c) of automatically located earthquakes (grey dots) overlaid with a 15-event moving average (black lines). d, Volcanic ash index (from SEVIRI InfraRed satellite) and crater dimensions from SAR imagery analysis. Crater depth is estimated with reference to the 2002 platform at around 3,190 m (Methods). The around 6 h effusive activity and main ash column emission at the summit (23 and 25 May) are marked by the red shading and dotted lines, respectively.
