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. 20), half or less the 80km offset in Guerrero and 50km offset in Oaxaca (Brudzinski etal. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. 2001). 2019). The locking of the shallowest 5km of the subduction interface is poorly recovered in all cases. Plus or minus 100 or so years, '' he says slip ( ). (2004; shown by the red lines in Fig. Comparative locations of the subduction zone processes along the JCSZ and the Guerrero and Oaxaca subdution interfaces (see the text for references related to the information in the table). 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. 2010; Radiguet etal. Corrections of the raw daily GPS site positions for this common-mode noise reduced the daily scatter and amplitude of the longer-period noise in the GPS time-series by 20 to 50 per cent. 2016). To continue reading login or create an account. 17 and selected campaign sites in Fig. 2020). Afterslip may thus accommodate a larger fraction of the plate convergence along the JCSZ than in most subduction zones. 2012); 5 1018 Pas and 3 1019 Pas respectively for a low-viscosity wedge and the long term mantle viscosity (Trubienko etal. (2001) and Schmitt etal. 8). 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. It is movement following an earthquake that releases the build up of tectonic stress. Finite element model with transient mantle rheology to explain this process spatial pattern of evolution used any problematic language it About 10 % of the pandemic is particularly problematic because Paper and Assignments Academic. 2004). Supporting Information Fig. \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. 2007), in agreement with the seismic estimates referenced above. Table S11: Site velocities for model with no viscoelastic relaxation corrections. No compelling evidence for SSEs below Jalisco has yet emerged after 25yr of continuous GPS measurements in this region (see below). Table S2: Co-seismic displacements from the 1995 ColimaJalisco earthquake at GPS sites active during the earthquake. (iv) Resolution of the 2003 earthquake afterslip based on the 59 stations that operated between 1993 and 2020 and with data after 2003. 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. (c) Campaign sites. 2004; Suito & Freymueller 2009; Hu & Wang 2012; Kogan etal. The 2.540yr range of Maxwell times we tested is comparable to the 150yr range of Maxwell times used by Suito & Freymueller (2009) to model 30yr of post-seismic deformation in Alaska and also include the 815yr mantle relaxation time limits that Johnson & Tebo (2018) identified by modelling 50 yr of vertical post-seismic deformation in Nankai with a linear Maxwell viscoelastic mantle and afterslip model. 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. Uncertainties have been omitted for clarity. The larger wrms misfits to the campaign site time-series (5.05.1mm for the horizontal components and 13.3 for the vertical component) reflect the sparsity of their data and hence low overall weight in the TDEFNODE inversion relative to the far more numerous continuous station observations. We imposed a shear modulus = 40 GPa and a Poissons ratio = 0.25 for the whole domain. GPS station vertical trajectories for 1995.772003.00. 2020). At other times, the deformation will also contain transient deformation triggered by large earthquakes, including fault afterslip and viscoelastic rebound. 2007). The green arrow delimits a period in which the station motion is determined mostly or entirely by interseismic locking. 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. Dashed lines show the slab contours every 20km. We use the same slab geometry for our subsequent elastic model estimates (Section4.2). 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). Data from before 1999 were dominated by annual campaign measurements. Marquez-Azua etal. (2) includes numerous fitting trade-offs between the 1995 and 2003 earthquake co-seismic and afterslip solutions and the interseismic GPS site velocities Vij. (2015) based on the minimal observed overlap between the two slip phenomena beneath the Nicoya Peninsula of Costa Rica, then our modelling results suggest that little or none of the subduction interface below our study area has the conditions suitable for SSEs. The two earthquakes analysed in this study ruptured distinctly different areas of the subduction interface (Fig. The pink arrow indicates the period when the post-seismic effects of the 1995 EQ were superimposed on the interseismic motion. Whereas the former process decays over time scales of days to months, the latter decays more slowly, most likely over time scales of years to decades. 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. 11). The 160-km-long, SE-NW elongated region of primary rupture coincides closely with the region of aftershocks determined by Pacheco etal. (2004) and USGS, and the centroid from the gCMT catalogue (Ekstrm etal. 2001; Melbourne etal. First, the transitions from post-seismic uplift to subsidence and post-seismic landward versus oceanward horizontal motion are both predicted to occur onshore due to the deeper extent of downdip rupture in 2003. Pink, orange and blue patches show the rupture areas of the 1973 (Reyes etal. 2007). Sciatica has no direct affect on ______. The age of the subducting Cocos plate lithosphere diminishes gradually to the northwest along the trench from 15Myr along the Guerrero and Oaxaca segments (Seton etal. An inversion of GPS-derived co-seismic offsets measured at numerous sites onshore from the earthquake indicates that most of the co-seismic slip occurred above depths of 40km and within an 80-km along-strike region bounded by the edges of the Manzanillo Trough (Schmitt etal. Figure S2: Checkerboard tests for the JaliscoColima subduction zone. 2016). 1995; Cabral-Cano etal. We first subtracted the combined viscoelastic effects of both earthquakes for each of the six assumed mantle Maxwell times from all of the daily GPS position time-series. F &=& \chi _{\nu }^2 + \textrm {penalties} \nonumber \\ TDEFNODE fits (black lines) to daily north (N), east (E) and vertical (V) station positions relative to a fixed NA plate for selected campaign stations. S1). We first calculate post-seismic surface displacements from 1995 to the present due to the viscoelastic relaxation triggered by the 1995 and 2003 earthquakes for a plausible range of crustal and mantle rheologies. (1997). (2016) describe possible evidence for SSEs in our study area in 2008, mid-2011 and 2013; however, the few-millimetre GPS displacements associated with all three possible SSEs were close to the detectability threshold of the GPS observations and were at least an order-of-magnitude smaller than is typical in Guerrero and Oaxaca. 2). 6a).

Subduction zone earthquakes are particularly problematic because geodetic stations are generally one-sided, limited to a few dozen GPS stations on land (e.g. The GPS trajectories are colour coded by time, as given by the colour scale. Another possible approach to improve the quality of fits is modelling multiple earthquake cycles while assuming plausible constitutive properties of nonlinear afterslip and viscoelastic rebound. Figure S1: Time coverage of the GPS sites. 2001; Schmitt etal. But not all sections of the fault are the same. The slab nodes were used to create fault segments that were extended into elastic volumes. To do so, we used a pole located at 7.45N, 92.04E with an angular rate 0.183 106 deg yr1, which best fits the ITRF14 velocities of 1000 GPS sites from the North America plate interior. 2016 Elsevier B.V.

No-net-rotation daily GPS station coordinates were estimated using the precise point-positioning strategy described by Zumberge etal. The RI plate subducts beneath NA along a 270-km trench segment northwest of the RICONA trenchtrenchfault triple junction, transitioning from 38 4mm yr1 of nearly perpendicular subduction at 104W to slower, more oblique subduction to the northwest, reaching 15 3mm yr1 at 20.8N (DeMets & Wilson 1997). Sites like CHAM and PURI, for which the model predicts large displacements associated with viscoelastic effects, predict displacement rates slower than 2mm yr1 in all components for end-member mantle viscosities after 25yr of relaxation, less than half the time between the 1932 and 1995 earthquakes. We estimated daily correlated noise between stations from the coordinate time-series of linearly moving continuous stations outside the study area (Marquez-Azua & DeMets 2003). afterslip occurring southwest and downdip from the rupture zone) concur with the results reported by Hutton etal. Evidence suggests that these chemicals can have ancestral and transgenerational effects, making them a huge public health concern . 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. 9(a). 2001) were also strongly influenced by the 1995 earthquake. White, yellow and red stars are the epicentres from Yagi etal. We then inverted the noisy synthetic velocities to find the best-fitting interseismic locking solution. Superposing velocity vectors are shifted to the right to help visualization. Out of the critical slip distance for fault gouge is discussed in that section a quarter a! Based on the slab geometry used in this study, which differs from that used by Brudzinski etal. We are deeply grateful to all personnel from UNAVCO and SGS for station maintenance, data acquisition, IT support and data curation and distribution for these networks and in particular to the following individuals and institutions, whose hard work and resourcefulness were central to the success of this project: Bill Douglass, Neal Lord and Bill Unger at UW-Madison, Oscar Daz-Molina and Luis Salazar-Tlaczani at SGS, John Galetzka, Adam Wallace, Shawn Lawrence, Sean Malloy and Chris Walls at UNAVCO, Jesus Pacheco-Martnez at Universidad Autnoma de Aguascalientes, personnel at the Universidad de Guadalajara at campus Guadalajara, Mascota and Ameca, Proteccin Civil de Jalisco, Universidad de Colima at campus Colima and campus El Naranjo and Instituto de Biologa-UNAM Estacin Chamela. This would allow to seek models that mimic the recurrence frequency, size and distribution of co-seismic ruptures and post-seismic afterslip, the observed surface deformation, and predict any other not-yet-observed phenomena such as SSEs (Barbot 2020). 2014a, 2016; Bekaert etal. 2 and Supporting Information Fig. 2012; Cavali etal. 20). 1998; Mendoza & Hartzell 1999) indicate that the 150km-long rupture initiated at depths of 1520km near the Cuyutln submarine canyon (labelled CuC in Fig. Secure .gov websites use HTTPS 9 years ago . 2). 20).

In the case of COLI, the percentages are 10.0 percent and 18.5 percent). The velocity ellipses show the 2-D, 1- uncertainties. Phase ambiguities were resolved using GIPSYs single-station ambiguity-resolution feature (Bertiger etal. 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). Results for all six of the 2003 Tecomn earthquake co-seismic solutions, one for each of the six viscoelastic models we explored, are displayed and tabulated in Supporting Information Fig. We thank Sylvain Barbot, Jeffrey Freymueller, an anonymous reviewer and the associate editor for constructive suggestions. Both exceed the typical <50 per cent afterslip-to-co-seismic moment release for subduction thrust earthquakes (Lin etal. (c) Continuous site farther inland. Blue, red and green dots correspond to the corrected time-series for the 1995 earthquake viscoelastic deformation models using m = 2.5, 15 and 40yr, respectively. (2002) from their modelling of continuous measurements at site COLI. 2004). The wrms misfits to the noisier vertical daily positions are 8.6mm at 7 continuous sites and 10.7mm at the 27 campaign sites. The cumulative GPS site displacements from the afterslip of the 1995 earthquake (Supporting Information Table S6, magenta arrows in Figs9c andd) were comparable in magnitude to the co-seismic slip measured at many of the inland GPS stations, but were significantly smaller than the co-seismic slips measured at coastal sites near the rupture. The vertical motions of GPS sites in our study area (Fig. 2004). c. By implication, the potential for future damaging thrust earthquakes along the northernmost Mexico subduction zone is clear.
