Figure 4. Waveform fits of the horizontal components for high-rate GPS station HSHX in displacement (left) and velocity (right), with the synthetics in red and data in black. All the waveforms are filtered to 0.02 – 0.4 Hz. Peak amplitude of the data is indicated at the end of each waveform pair. Synthetic waveforms are decomposed into the contributions from Seg.1 - 6, Seg.7 - 8 and Seg. 9 – 10. Dashed circles highlight the waveform segments that show different relative amplitude to the earlier rupture between displacement and velocity waveforms.
