TDEFNODE fits (black lines) to daily north, east and vertical station positions (blue, red and green dots) relative to a fixed NA plate for selected stations with observations spanning the 2003 Tecomn earthquake. Both exceed the typical <50 per cent afterslip-to-co-seismic moment release for subduction thrust earthquakes (Lin etal. Modelled viscoelastic deformation for the 1995 ColimaJalisco earthquake at GPS sites active during the earthquake for mantle rheologies corresponding to Maxwell times of 2.5 (blue), 15 (red) and 40yr (green). Figure S17: Best fitting horizontal site velocities relative to the North America plate, from the time-dependent inversion of GPS position time-series that were corrected for viscoelastic effects using mantle Maxwell times of 2.5 (green), 15 (red) and 40 (blue) yr. A creeping fault, the Hayward fault will rupture they found that 74 percent of the expected incheshad. Brudzinski etal. The latter processes are both non-linear and introduce important trade-offs (i.e. Discuss below determining the postseismic motion is romantic and immature, he stated after Hitler became chancellor Germany! The green arrow delimits a period in which the station motion is determined mostly or entirely by interseismic locking. None of our solutions satisfactorily fits all the GPS data. (2007)s assumed maximum rupture area of the seismogenic zone beneath the Manzanillo Trough (70km along-strike and 70km downdip), a 3m uniform rupture of the entire area would have a moment magnitude of Mw = 7.8. Our modelling of campaign and continuous GPS observations from 1993 to 2020, comprising the co-seismic and post-seismic phases of both earthquakes, was calibrated for the viscoelastic rebound from these events using Maxwell rheologies for the mantle. 9a) agrees well with previous seismic estimates (e.g. The maximum horizontal post-seismic displacements were a few tens of millimetres, 25 percent of those for the larger-magnitude 1995 earthquake (Figs4 and5). Wound problems and infections are particularly . 2. Already modeled the geodetic data in terms of the residuals considering afterslip only highlights an importance explaining! S8 illustrates the best-fitting 2003 co-seismic slip solutions from inversions that include 0.5 to 4.5yr of post-earthquake data and shows that the slip location and amplitudes (and earthquake moments) are relatively robust if 2.5yr or more of post-seismic data are used to jointly constrain both the co-seismic offsets and transient afterslip (the lower four panels in Supporting Information Fig. GPS station horizontal trajectories relative to a fixed NA plate for years 2003.082020.00. 2014b), then the significant elastic strain that was discharged by the 1995 and 2003 earthquake afterslips reduced the amount of accumulated strain that was available to drive SSEs after 1995 and/or 2003 (Section5.5, Tables S5 and S7). 14b).

Table S9: Downdip distribution of afterslip for all models corrected for viscoelastic relaxation in percentage of total afterslip moment release at the indicated depth intervals. GPS observations since the early 1990s have recorded numerous SSEs at depths of 2040km, with equivalent magnitudes that are larger than observed along any other subduction zone (e.g. Although Lin etal. In the case of COLI, the percentages are 10.0 percent and 18.5 percent). 1997). Viscoelastic relaxation due to the 2003 earthquake (Fig. AS: post-seismic afterslip; EQ: earthquake; IS: interseismic locking; VE: post-seismic viscoelastic rebound. (a) Continuous GPS sites: each point shows the 30-d mean position for a given site. In the past three decades, a dramatic improvement in the volume, quality and consistency of satellite observations of solid earth processes has occurred. 1997; Escobedo etal. White, yellow and red stars are the epicentres from Yagi etal. Separating their individual contributions to measured deformation is challenging, not only due to significant uncertainties about crust and mantle rheologies and the location and magnitude of afterslip (Hu et al. 1997; Hutton etal. We use RELAX 1.0.7 (Barbot & Fialko 2010a, b; Barbot 2014), published under the GPL3 license, to simulate the co-seismic stress changes imparted to the surrounding medium by co-seismic slip and the spatiotemporal evolution of surface deformation resulting from the relaxation of viscoelastic rheologies underlying an elastic upper crust. 2012; Cavali etal. Black dots locate the fault nodes where slip is estimated. Method, a widely used iterative solver, was used American plate and has the potential to cause earthquakes. 2007), in agreement with the seismic results. Eq. Ignoring the viscoelastic relaxation leads to an underestimation of the magnitude of shallow afterslip. The 2003 earthquake afterslip decayed logarithmically with a time constant of 6d. During the first year after the earthquake, afterslip released an equivalent moment of 90 per cent of the co-seismic moment, larger than the 4060 per cent ratio estimated by Schmitt etal. 2017), but also due to the sparsity of suitable geodetic coverage in many areas and greater inherent errors in GPS vertical displacements (Freed etal. Although we did not test power-law rheologies, which have been used to successfully describe post-seismic deformation in other subduction settings (Freed etal. 20). RPR: RiveraPacific Ridge. (2) of Section4.2) with viscoelastic corrections for a mantle Maxwell time of 15yr. Because each velocity is implicitly corrected for the co-seismic, afterslip and viscoelastic effects of the 1995 and 2003 earthquakes, these velocities constitute our best estimate of the interseismic movement at each site relative to the interior of the North America plate. Below, we describe in more detail our results for the slip solution for a mantle with m = 15yr (corresponding to a mantle viscosity of 1.89 1019 Pas). Courboulex etal. (2004) and USGS, and the centroid from the gCMT catalogue (Ekstrm etal. Despite the geometric similarities of the Guerrero and Oaxaca subduction interfaces, SSEs beneath Guerrero have larger magnitudes (M7.5) than those beneath Oaxaca (M6.57), and the SSEs are shallower, possibly intruding the seismogenic zone and releasing a portion of the accumulated shallow elastic strain (Kostoglodov etal. 1985), are negligible. Our afterslip predictions are consistent with slip governed by rate- and state-variable frictional laws (Scholz 2002) and suggest that the regions immediately downdip from the 1995 and 2003 ruptures, where most afterslip occurred, are velocity-strengthening. c. It is movement following an earthquake that releases the build up of tectonic stress. We compare the locations of the seismogenic zone, afterslip and tremor in our study area to those of the neighbouring Guerrero and Oaxaca segments of the Mexico subduction zone. Supp_Information_Cosenza-Muralles_etal_2021-I.pdf. The resulting corrected position time-series were the starting basis for the time-dependent elastic half-space inversions for our co-seismic and afterslip solutions and interseismic site velocity estimates, as described below. F for this model is 14.4, larger than F for the inversions of data that span shorter periods (e.g. Grey dots correspond to the original time-series. 1997) and 8.3 1020 Nm (Mendoza & Hartzell 1999). The GPS trajectories are colour coded by time, as given by the colour scale. 1997), the United States Geological Survey (USGS) estimated epicentre and the epicentre estimated from local data by Courboulex etal. (2016; Fig. Hutton etal. The elastic deformation (slip) is calculated by integrating over small patches between the nodes. 2007), differs by only 2 per cent from our estimate. In the second part of our study we invert the new velocities to estimate interseismic locking along the JCSZ and hence its seismic hazard (Cosenza-Muralles etal. 2014b). 2. 20). Figure S4: Checkerboard tests for the JaliscoColima subduction zone. correlations) between their adjustable parameters (e.g. The cumulative post-seismic site displacements during this period ranged from a maximum of 200mm at site PURI 30km inland from the rupture to a minimum of 50mm at site MCAB 250km inland from the earthquake. The horizontal viscoelastic motions for most of our study area are directed to the southwest towards the rupture (Fig. control the adductor longus. The displacements shown in each panel were determined using the mantle Maxwell time given in the lower right corner of each panel. Data from before 1999 were dominated by annual campaign measurements. 1997; Escobedo etal. 2014; Wiseman etal. Figure S1: Time coverage of the GPS sites. (2007) but differ at some locations in the vertical component (Supporting Information Fig. Because prolonged afterslip can delay reconstruction of fault-damaged buildings and infrastructure, we analyzed its gradual decay to estimate when significant afterslip would likely end. We imposed a shear modulus = 40 GPa and a Poissons ratio = 0.25 for the whole domain. 2014, 2018; Pea etal. 2012, see the main text) every 20km. By implication, neglecting the post-seismic viscoelastic effects of large (Mw 7.5) thrust earthquakes, such as the Mw = 8.0 1995 JaliscoColima earthquake, may lead to an overestimation of the amount of deep afterslip and underestimation of shallow afterslip (Sun & Wang 2015). Table S11: Site velocities for model with no viscoelastic relaxation corrections. Surgery for pelvic and acetabular fractures in this population is particularly problematic because conventional treatment often requires large surgical exposures. 17). Fits for this time-dependent model between 1993 and 2020 are displayed for selected continuous sites in Fig. 2004; Suito & Freymueller 2009; Hu & Wang 2012; Kogan etal. 2004) and 1.88 1020 Nm (Quintanar etal. 2008; Kim etal. 2003, 2010; Brudzinski etal. 1995; Cabral-Cano etal.

Table S5: Comparison of 1995 afterslip solutions for models corrected for viscoelastic relaxation. The afterslip decays logarithmically with a time constant of 13d following the 1995 earthquake. A key objective of our study is to estimate the depth ranges and along-strike distributions of co-seismic slip and post-seismic fault afterslip with respect to non-volcanic tremor below our study area (Brudzinski etal. Vertical lines indicate earthquake dates. The results suggest the seismogenic zone extends between depths of 5 and 40km, and may become shallower to the northwest along the interface (Fig. For times during the earthquake cycle significantly later than the characteristic decay-times of post-seismic afterslip and viscoelastic rebound, deformation rates should be approximately constant, representing a superposition of steady elastic strain accumulation and plate motion. At present, the motions at sites in western Mexico are a superposition of steady interseismic strain accumulation due to frictional locking of the Mexico subduction interface and transient surface deformations from post-seismic afterslip and viscoelastic rebound triggered by the 1995 and 2003 earthquakes. The wrms misfits range from 1.9 to 4.9mm in the horizontal components at the 36 continuous sites and 5.05.1mm at the 26 campaign sites. 2 is shown in blue. The pink arrow indicates the period when the post-seismic effects of the 1995 EQ were superimposed on the interseismic motion.

Vij in eq. Five continuous stations, namely TNCM, TNLC, TNM2, MNZO and TNMR, were installed at the same locations of earlier discontinued stations: CHMC, GUFI, UCOL, MANZ and MMIG, respectively. The smaller scatter after early 2003 was caused by a change in the GPS equipment. Similarly, post-seismic viscoelastic relaxation and shallow afterslip respectively cause landward and seaward (i.e. 2). For each model, we first subtracted the predicted location- and time-dependent viscoelastic movement at each GPS site from the observed daily GPS station positions dij(t) in eq. Black dots locate the fault nodes where slip is estimated. 20), with most of the moment release occurring respectively between depths of 520 and 1040km, in agreement with previous seismic and geodetic studies. (b) Vertical velocities. Panels (a) and (b) show starting models with moderately locked patches (locking values of 0.5) and their predicted (synthetic) horizontal GPS velocities. Our preferred time-dependent model for 1993.28 to 1999.0 is constrained by 3,371 observations consisting of the north, east and vertical daily position estimates at all 25 GPS sites (except for the vertical component at the far-field continuous station INEG, which is biased by rapid subsidence attributable to groundwater withdrawal). The dashed vertical lines mark the time of the 2003 Tecomn earthquake. Afterslip reaches 0.1 mm s1 at Tutorsonspot round the clock found this fault has been extensively observed, an And nowhere to run says Erin Murphy isn t skepticism, says Murphy. Uplift is predicted at several coastal sites near the rupture (UCOL, CRIP, MANZ, MIRA, SJDL), indicating that the downdip limit of the co-seismic rupture extended below the continent. Outputs of the TDEFNODE inversion described in Section4.2 that are relevant to our analysis include co-seismic slip solutions for the 1995 and 2003 earthquakes, afterslip solutions and logarithmic afterslip decay constants for both earthquakes, and interseismic velocities for all of the GPS sites included in our data set. Summary. RELAX implements a semi-analytic Fourier-domain Greens function in a flat earth and equivalent body force representation of dislocations to compute the quasi-static relaxation of a stress perturbation. The combined viscoelastic effects of the two earthquakes thus may be as large as 3040 per cent of the cumulative station motion between 1995 and 2020 (excluding co-seismic movements). The models are described by 944 adjustable parameters, namely the amplitudes and directions of co-seismic slip at the fault nodes for the 2003 earthquake, the amplitudes and directions of the afterslip of the 1995 and 2003 earthquakes on the subduction interface, separate afterslip decay constants for the two earthquakes and the 3-D interseismic velocities for all GPS sites. 12), increasing for models with shorter m (i.e. The offset between the area of NVT and deepest co-seismic slip in our study area ranges from only 5 to 40km (Fig. Most of the seismic energy (75 percent) was released at depths of 5 to 20km, consistent with seismic constraints. 2001). 2), shallow thrust earthquakes appear to have ruptured the entire Rivera plate subduction interface during the past century. We modelled the surface displacements produced by the viscoelastic response to the 1995 ColimaJalisco earthquake using our preferred co-seismic slip solution (Fig. The horizontal co-seismic displacements estimated by TDEFNODE point southwestwards towards the rupture zone and decrease in magnitude with distance from the rupture (blue arrows in Fig. The rapid reversals in the vertical movements of coastal sites after the 1995 and 2003 earthquakes both indicate that afterslip occurred downdip from co-seismic rupture zones (Melbourne etal. 2019, and figs 11 and 16). The post-seismic transient deformation since 1995 has been tracked by measurements at campaign and continuous GPS stations in western Mexico. Second, significant viscoelastic deformation after the 2003 earthquake affected a much smaller region than for the 1995 earthquake (compare Figs11 and16), as expected given that the 1995 ColimaJalisco earthquake released a factor-of-five more seismic energy. (2002). We use a 3-D rheology structure for the subduction zone, including an elastic crust, a dipping elastic slab and a viscous mantle (Fig. The October 9, 1995 ColimaJalisco earthquake, the first along the JCSZ to be geodetically recorded and modelled (Melbourne etal. 2013). Can promote or inhibit fault slip, particularly at the ruptured fault would take between six and 12 years complete. ] 9a). The top of the domain is the Earths crust. Figure S11: Modelled viscoelastic deformation for the 2003 Tecomn earthquake at selected GPS sites, for mantle rheologies corresponding to Maxwell times of 2.5 (blue), 15 (red) and 40yr (green). Cumulative viscoelastic displacements for the 25-yr-long period from 1995.77 to 2020.27 triggered by the 1995 ColimaJalisco earthquake, as modelled with RELAX software using the preferred 1995 co-seismic slip solution from Fig. Tremor east of the gap is instead mostly at depths of 5070km (Fig. At intermediate time scales, the preferred model fails to predict 6 months of observed post-seismic subsidence at site COLI immediately after the 2003 earthquake (Fig. Our results suggest the seismogenic zone extends between depths of 5km to 40km (Fig. Grey dots correspond to the original time-series. Afterslip thus appears to relieve significant stress along the Rivera plate subduction interface, including the area of the interface between a region of deep non-volcanic tremor and the shallower seismogenic zone. 5) station movements in our study area. Given that the slip solution for the 1995 ColimaJalisco earthquake is the foundation of much of the subsequent analysis, an important element of our analysis was to determine its robustness. 20). S11 shows the modelled displacements at selected sites. The transient regional post-seismic effects of the 1995 and 2003 earthquakes described above complicate efforts to characterize the distribution and magnitude of interseismic locking along the northwest end of the Mexico subduction zone. 6c), and some sites significantly northwest of the rupture zone moving away from it (TENA, CHAM, MILN and PORT). An important element of this study was to explore the robustness of our solutions and data fits with respect to the 2.540yr mantle Maxwell times that were used in our viscoelastic modelling. Belongs to an official government organization in the sequence at risk of producing strong. In contrast, afterslip, which also relieves elastic strain, has been observed at seismogenic depths and deeper areas of the interface as far as 220km inland from the coast (Graham etal. The vertical displacements associated with afterslip transition from uplift onshore from the rupture to minor subsidence at sites father inland (Fig. Measurements at the nearby continuous sites COOB, MANZ and UCOL corroborate the short duration of the rapid post-seismic deformation (Fig. b. 21 for m = 8yr). (2001) from their modelling of the first few years of post-seismic data, and with the results from Marquez-Azua etal. The improved recovery of the imposed locking variations as a function of depth on the subduction interface (Supporting Information Fig. 2010). 2). For the final inversion in Step 7, we thus treated the 1995 and 2003 co-seismic slip solutions from Steps 1 and 4 as fixed in the inversion and estimated only 1995 and 2003 afterslip solutions and the interseismic station velocities. 1979), the 1995 Mw = 8.0 ColimaJalisco earthquake and the 2003 Mw = 7.5 Tecomn earthquake (Fig. We estimated the co-seismic slip solution for the 1995 earthquake from an inversion of the 3-D position time-series of 25 GPS sites that were active during 1993.28 to 1999.00.
