Supporting Information Figs S15 and S16 respectively display the six best-fitting 1995 and 2003 earthquake afterslip solutions, one for each of the viscoelastic models we explored. 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. 1 However, these figures do not include the marketing content online, in print, at the movies, in video games, or at school. 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. The horizontal co-seismic displacements predicted by TDEFNODE point towards the rupture zone at 29 of the 30 GPS sites that were active at the time of the earthquake, excluding only site SJDL, which lies at a nodal location with respect to the earthquake (Fig. To buildings and infrastructure will be the mechanical interaction of the postseismic motion all. But not all sections of the fault are the same. 20). 2001; Melbourne etal. 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. As well as being a stimulant, caffein TDEFNODE slip solution for (a) the 2003 Tecomn earthquake and (b) its post-seismic afterslip (integrated over the 2003.062020.00 interval) for a model using time-series corrected for the viscoelastic effects of a mantle with m = 15yr. In CM21-II, we use standard checkerboard tests to test the ability of the GPS network in western Mexico to resolve locking along the JaliscoColima subduction interface. At the continuous site COLI, which is directly onshore from the 2003 rupture, rapid post-seismic deformation ceased by mid-2003 and the site resumed its pre-1995 northeast-directed motion by 2005 (Figs3, 6 and7). 2004; Yoshioka etal. 1997; Hutton etal. In this work, we address these questions by On: Jul 29, 2013. afterslip rather than postseismic relaxation. The latter processes are both non-linear and introduce important trade-offs (i.e. Evidence suggests that these chemicals can have ancestral and transgenerational effects, making them a huge public health concern . S1 and Table S1 document the spatial and temporal coverage of our observations. The computational domain, which is a rectangular 512 512 256 grid with horizontal and vertical grid steps of 2.5km, is several times larger than the length of co-seismic rupture (not shown). (2001) for the same period. Bandy etal. Table1 summarizes the depths of these different processes. 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.

Thirty sites were operational during the January 2003 earthquake, of which five were continuous and two began as campaign stations and were converted to continuous operation after the 2003 earthquake (PURI and COOB). b. Dashed lines show the slab contours every 20km. Afterslip may thus accommodate a larger fraction of the plate convergence along the JCSZ than in most subduction zones. Grey dots correspond to the original time-series. 14b).

The vertical motions of GPS sites in our study area (Fig. Global distribution of earthquakes c. Glob 20 of the main document. White, yellow and red stars are the epicentres from Courboulex etal. 14d), decreasing with distance from the rupture zone and transitioning to minor uplift at locations farther inland. The computation is performed in a uniform Cartesian grid defined by the number of nodes in the three directions. They speculated that fault-normal unclamping downdip from the rupture zone and mild unclamping at the southeast end of the rupture possibly encouraged large afterslip. 2007; Larson etal. Black dots locate the fault nodes where slip is estimated. The interval used for the inversion is shown in each panel. S2), (ii) Resolution of 1995 earthquake afterslip based on the 33 stations that operated between 1993 and 2020 and with data that predates 2003 (Supporting Information Fig. Inversions of seismic waveforms for the 1995 and 2003 earthquakes yield slip solutions with depths shallower than 30km (Sections 5.1 and 5.3), consistent with the depth ranges of our GPS-derived co-seismic slip solutions. The remaining 13 sites, all campaign stations, were first occupied in March of 1995. Fig. Black dots locate the fault nodes where slip is estimated. For example, the estimated co-seismic moments and slip amplitudes for models derived from inversions of as little as 2yr of post-seismic data differ by only 0.12.3 percent from those for the preferred model and by only 1.85.2 percent for models derived from inversions of all the data gathered between the 1995 and 2003 earthquakes. We estimated a co-seismic slip solution for the 2003 Tecomn subduction earthquake for each of the six viscoelastic models that are described in the previous section. 2020). Our modelling indicates that afterslip is an important mechanism by which plate convergence is accommodated in this transitional region. 1979), 1995 (Pacheco etal. Figure S3: Checkerboard tests for the JaliscoColima subduction zone. Afterslip occurs because of delayed movement of the earth. 2), shallow thrust earthquakes appear to have ruptured the entire Rivera plate subduction interface during the past century. Reg. The afterslip decays logarithmically with a time constant of 13d following the 1995 earthquake.

Dashed lines show the slab contours every 20km. Site displacements with increasing time towards the northern map boundary indicate station uplift, whereas displacements towards the southern boundary indicate site subsidence, with time increasing eastward (to the right) on the map. The June 3 event was the largest earthquake in Mexico throughout the 20th century (Singh etal. 2016). The location of the co-seismic slip agrees closely with the seismologically derived solution of Yagi etal. 9a). (2004) and USGS, and the centroid from the gCMT catalogue (Ekstrm etal. Our checkerboard tests (Supporting Information Figs S2S5) suggest that the geographic distribution and density of GPS sites in our study area are good enough to resolve the relative depths of seismic slip and afterslip and their locations updip from NVT. The black dashed line marks the time of the 2003 Tecoman earthquake. The latter two processes decay with different characteristic timescales after the earthquakes. The location of NVT in this segment correlates with zones of slab dehydration with isotherms of 400500 C (Manea & Manea 2011; Manea etal. Think most companies, particularly at the ruptured fault would take between six and 12 years to 300 between Immature, says Erin Murphy for explaining the observation data challenging problem because of the afterslip13.8! The mantle Maxwell times m used for the corrections are indicated in each panel. 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. The afterslip solutions for both earthquakes suggest that most afterslip coincided with the rupture areas or occurred farther downdip and had cumulative moments similar to or larger than the co-seismic moments. (1979). The pink arrow indicates the period when the post-seismic effects of the 1995 EQ were superimposed on the interseismic motion. mantle viscosity, mantle-crust interface depth and afterslip decay time). 3) varied by only 10 per cent for the wide range of mantle Maxwell times we tested (Supporting Information Table S12), including an inversion of the GPS position time-series without any viscoelastic corrections (Supporting Information Section S1, Tables S3, S5, S7, S9 and S11, and Figs S19 and S20). A reversal in the vertical movement of a GPS site directly onshore from the rupture indicates that afterslip propagated downdip to areas of the subduction interface beneath the coastline within days following the earthquake, similar to the post-seismic behaviour of the 1995 earthquake (Schmitt etal. 2005) that we refer to hereafter as the Manzanillo Trough. The maximum horizontal post-seismic displacements were a few tens of millimetres, 25 percent of those for the larger-magnitude 1995 earthquake (Figs4 and5). Afterslip ( Marone et al on the fault has been extensively observed, suggesting an role Interaction of the residuals considering afterslip only highlights an importance for explaining the observation data longer one. 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. (2001; magenta arrows). S9 and Tables S3 and S4. Arrows show the horizontal displacements and colours indicate the vertical displacements. Melbourne etal. Black dots locate the fault nodes where slip is estimated. Similarly, post-seismic viscoelastic relaxation and shallow afterslip respectively cause landward and seaward (i.e. 2010), thrust earthquakes for both segments are typically shallower than depths of 25km (Surez & Snchez 1996; Pacheco & Singh 2010). In the Supporting Information, we describe results from a TDEFNODE inversion of the GPS position time-series assuming that fault afterslip was the source of all the observed transient post-seismic deformation (i.e. Black dots locate the fault nodes where slip is estimated. The blue line delimits the earthquake aftershock area (Pacheco etal. 2019); (6) different viscosities for the mantle below the oceanic and continental crust (Hu & Wang 2012; Li etal. The main computational cost of the CG method is a repeat of the computing matrix-vector product such as Kv , where v is an arbitrary vector. 4) and vertical (Fig. The horizontal displacements attributable to afterslip were as large as or larger than the co-seismic offsets at many sites (Fig. The improved recovery of the imposed locking variations as a function of depth on the subduction interface (Supporting Information Fig. 9(a). (2004; shown by the red lines in Fig. b. 2016; Barbot 2018; Qiu etal. Grey dots correspond to the original time-series. 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. Panels (c) and (d) respectively show the horizontal and vertical site motions that are predicted by the co-seismic and afterslip solutions from panels (a) and (b) at sites active during the earthquake. 1.

Introduction 20). 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. Plasticizers such as phthalates and bisphenols are particularly problematic because they are present in many consumer products and exposure can begin in utero and continue throughout the lifetime of the individual. Only stations that where operating during the earthquake are shown. 1997). We estimate preferred slip solutions for the 2003 earthquake from GPS data that include 2.5yr of post-seismic data, the minimum necessary, in order to minimize unavoidable trade-offs between the relative contributions of fault afterslip and mantle viscoelastic flow to the post-seismic deformation. 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. (2001) and Schmitt etal. The 1932 June 3 and 18 earthquakes ruptured the shallow part of the RI-NA interface in a combined area of 280km by 80km, as estimated from aftershocks (Singh etal. Synonym Discussion of problematic. Secure .gov websites use HTTPS 9 years ago . 1997) and 8.3 1020 Nm (Mendoza & Hartzell 1999). Select one: a. In general, smaller values of m for the viscoelastic corrections, which correspond to larger magnitude short-term viscoelastic deformation, result in smaller estimated afterslip (Supporting Information Figs S15 and S16). Figs9(b) and14(b) respectively show the best-fitting 1995 and 2003 earthquake afterslip solutions derived from the GPS positions that were corrected by the representative m = 15yr viscoelastic model. Afterslip happens more frequently than spontaneous slow slip and has been observed in a wider range of tectonic environments, and thus the existence or absence of tremor accompanying afterslip may provide new clues about tremor generation. Global Positioning System (GPS) measurements in Jalisco began in the mid-1990s as part of an effort to study the regional subduction earthquake cycle and associated seismic hazards (DeMets etal. The 1995 and 2003 earthquakes were followed by large afterslip that partially overlapped their rupture zones and extended downdip to depths of 6065km. 1985). \end{equation*}$$, The parameters estimated in our TDEFNODE inversions consist of the amplitudes and rake of co-seismic and post-seismic slips at the fault nodes, the rake of the co-seismic slip and afterslip, the afterslip decay rates, and the linear station velocities. Estimating the locking solely from GPS time-series that predate the October 10, 1995 earthquake is not possible because such observations are limited to 19931995 data from continuous sites COLI and INEG (Supporting Information Fig. EQ: earthquake. In the past three decades, a dramatic improvement in the volume, quality and consistency of satellite observations of solid earth processes has occurred. S11 shows the modelled displacements at selected sites. No-net-rotation daily GPS station coordinates were estimated using the precise point-positioning strategy described by Zumberge etal. Estimating the degree of interseismic locking via modelling of GPS position time-series requires isolating the steady interseismic elastic strain from instantaneous offsets due to earthquakes and any transient deformation due to fault afterslip and/or viscoelastic rebound. Our estimated geodetic co-seismic moment of 9.71 1020 Nm, corresponding to Mw = 7.92 for = 40 GPa, is close to seismologic estimates of Mo = 1.15 1021 Nm (Dziewonski etal. In both areas, our afterslip solutions suggest 0.52 m of afterslip occurred as far downdip as the region of non-volcanic tremor (Fig. Both features of our 1995 afterslip model (i.e. We then inverted the corrected GPS position time-series while fixing the 1995 co-seismic slip solution to its preferred estimate (Fig. 20). The observed transient post-seismic motion is a superposition of the effects of three distinct processes: steady interseismic shortening due to fault relocking at the subduction interface, fault afterslip downdip and possibly along the seismogenic zone, and post-seismic viscoelastic mantle flow (Marquez-Azua etal. Other misfits occur at times that are 5yr or longer after the earthquakes. For this reason, we explored the sensitivities and fitting trade-offs during all seven stages of the above analysis to the assumed crustal/mantle rheologies and other assumptions in the inversion (such as slip smoothing and the lengths of the data windows that we used in Steps 1 and 4). The dashed orange line delimits the 1995 earthquake rupture area from Fig. Dashed lines show the slab contours (extended from Hayes etal. 1997). 2013; Graham etal. Support for this work during its various stages was provided by NSF grants EAR-9526419, EAR-9804905, EAR-9909321, EAR-0510553, EAR-1114174, the University of Wisconsin-Madison and the UW-Madison Department of Geoscience Weeks endowment funds. 2015). 2016). The observations during this period are best fit for a Maxwell time of 8yr (a mantle viscosity of 1 1019 Pas), although the fits for Maxwell times of 4 and 15yr are nearly as good (Supporting Information Table S12). The 3-D post-seismic effects of the Mw = 7.5 2003 January 22 Tecomn earthquake (Figs6 and7) were also apparent in most of our study area. The TDEFNODE misfits F (eq. The temporal linear dependency between afterslip and aftershocks shown here suggests a causative time-based relationship between these two processes, and therefore the temporal distribution of aftershocks associated to patches of afterslip would be modulated by the stressing rate associated with afterslip (e.g. 2013; Graham etal.
