Extended Data Fig. 1: Synthetic and observed migration images for an event from Malyn.
From: Identifying attacks in the Russia–Ukraine conflict using seismic array data
a, The synthetic case, including the migration images (or point spread functions) for P-wave only (top left), S-wave only (top right) and P-wave and S-wave (bottom right), including the derived location (marked by the dashed lines) and an uncertainty ellipse based on the 50th percentile of the point spread functions. The synthetic waveforms used to generate the migration image are shown at the bottom left. b, An observed example from our catalogue showing the waveforms with the theoretical arrivals (left) and the migration image with the associated location (top right). For each case, we show the time series of the coalescence function used to derive the origin time.
