Gallovic0.01; Gallovič et al. (2015) | Linear multitime window inversion approach with long duration of slip rate functions (equal to the assumed duration of the rupture process). Constraints: (1) smoothing by means of a prior k-2 covariance functions, and (2) positivity of the slip rate function. The smoothing weight is relatively small (perhaps not applicable in real-data application). | Butterworth bandpass filter in range of 0.05–0.5 Hz (four poles, causal) |
Gallovic0.1; Gallovič et al. (2015) | Same as Gallovic0.01 but with more severe smoothing (similar to that used in real-data applications). | Same as Gallovic0.01 |
Hoby; Razafindrakoto and Mai (2014) | Parametric (single-time window) inversion assuming triangular slip rate function. Parameters: rupture times, rise times, and peak slip rates. Metropolis algorithm is used to optimize the parameters considering L2 norm. | Butterworth bandpass in range of 0.01–1 Hz |
CedricT3; Twardzik et al. (2012) | Simplified source model considering two elliptical subfault patches, triangular slip rate function, and constant rupture velocities along the patches. Parameters: location and size of the ellipses, rupture velocities, and onset times of the subfault patches. Neighborhood algorithm is used to find the best fitting parameters considering L2 norm. | Butterworth bandpass filter in range of 0.1–1.0 Hz (four poles, two passes—acausal) |
Asano; Sekiguchi et al. (2000) | Multitime window linear inversion with spatiotemporal smoothing constraint. Weight of smoothing is determined by minimizing Akaike Bayesian information criterion. | Bandpass filter in range of 0.05–1.0 Hz |
