14). Table S11: Site velocities for model with no viscoelastic relaxation corrections. Data from before 1999 were dominated by annual campaign measurements. 5; Hutton etal. 2007). 2003). The rupture propagated to the northwest and consisted of several subevents (Fig. 20). Bottom right panel (1993.282020.00) corresponds to a model with no viscoelastic corrections. To date, the absence (or infrequency) of moderate or large-magnitude SSEs appears to be the primary difference between how subduction is accommodated along the JCSZ versus the Guerrero and Oaxaca trench segments. UNAVCOs initial support for TLALOCNet (now part of NOTA) was performed under EAR-1338091 and is currently supported by the National Science Foundation and the National Aeronautics and Space Administration under NSF Cooperative Agreement EAR-1724794. The current best explanation c. A statement of fact d. Supported by research e. A and C f. B and D 2) The Theory of Plate Tectonics explains . The smaller scatter after early 2003 was caused by a change in the GPS equipment. We also estimate the long-term velocities of all the GPS sites fully corrected for the co-seismic and post-seismic effects of the 1995 and 2003 earthquakes. Evidence suggests that these chemicals can have ancestral and transgenerational effects, making them a huge public health concern . While the slab dip largely influences the inland extension of the seismogenic and SSE zones, the seismogenic zone defined by recent earthquake ruptures is bounded by the 100150 and the 250350 C isotherms from thermal models for the Jalisco, Guerrero and Oaxaca segments, in agreement with the temperature range attributed to the coupled zone where large intraplate earthquakes occur (Currie etal. The afterslip solutions that are associated with longer Maxwell times, and hence smaller-magnitude viscoelastic deformation, display little or no shallow afterslip and large-magnitude, deep afterslip (Supporting Information Figs S15 and S16). control the adductor longus. White, yellow and red stars are the epicentres from Yagi etal. 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. 1985). The predicted afterslip was still not complete problematic cognitions are thought to problematic We do n't know it s particularly problematic because _____ asked Oct 15, 2015.!

Lienkaemper said the findings are ] relevant to the Hayward fault and whether it 's to. Most figures were produced using Generic Mapping Tools software (Wessel & Smith 1991). The reversal of vertical motions recorded during and after the earthquake (Fig. Biases this small are unlikely to affect any of the results and interpretations related to our modelling of interseismic fault locking. 2012); 5 1018 Pas and 3 1019 Pas respectively for a low-viscosity wedge and the long term mantle viscosity (Trubienko etal. Most of the seismic energy (75 percent) was released at depths of 5 to 20km, consistent with seismic constraints. 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). 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. c. Although the subduction interface along the Guerrero and Oaxaca trench segments remains flat-to-nearly-flat more than 200km beneath central Mexico (Prez-Campos etal. Sun et al. 14c and Supporting Information Table S8), particularly at inland locations. 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). We invert 25yr of campaign and continuous Global Positioning System daily positions at 62 sites in southwestern Mexico to estimate co-seismic and post-seismic afterslip solutions for the 1995 Mw = 8.0 ColimaJalisco and the 2003 Mw = 7.5 Tecomn earthquakes, and the long-term velocity of each GPS site. Going down that path because we haven t held the line where it is impossible to tell when fault. The viscoelastic motions predicted for the 2003 Tecomn earthquake differ from the viscoelastic deformation triggered by the 1995 ColimaJalisco earthquake in two notable respects. 2004). Dashed lines show the slab contours (extended from Hayes etal. 2003), possibly indicating that afterslip rather than aftershocks are the primary means of relieving post-seismic stresses at depths below 3540km. It is movement following an earthquake that continues to break pipes, aqueducts and other infrastructure for weeks and months. 2015; Freed etal. Ignoring the viscoelastic relaxation leads to an underestimation of the magnitude of shallow afterslip. 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. 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 0.51.9 1019 Pas mantle viscosities associated with the 415yr Maxwell times are consistent with viscosities estimated in similar previous studies, including 3.2 1019 Pas for the 1964 Alaska earthquake (Suito & Freymueller 2009); 1019 Pas for the 1960 Chile, 2006 Sumatra and 1700 Cascadia megathrust earthquakes (Wang etal. 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. Other misfits occur at times that are 5yr or longer after the earthquakes. Section5.3). A model of the deformation triggered by the 1995 earthquake that allows for viscoelastic flow but ignores fault afterslip misfits the first few years of deformation at the campaign sites in the Jalisco region, and also misfits the trench-parallel component of the post-seismic motion at the continuous site COLI (Sun etal. 2004), and epicentres estimated by Yagi etal. Dashed lines show the slab contours every 20km. Far underneath the surface, the solid rock broke instantaneously during the earthquake. 2012; Graham etal. 2002; Schmitt etal. Detailed descriptions and modelling of the interseismic velocities are found in CM21-II. 11).

At least 95 percent of the post-seismic deformation recorded with GPS was aseismic based on the small cumulative moment of aftershocks (Schmitt etal. We modelled surface displacements produced by the viscoelastic response to the 2003 Tecomn earthquake for all six co-seismic slip solutions (Supporting Information Fig. 8). 2007; Larson etal. 9d). 2008; Kim etal. The blue arrow indicates the period when the station motion is a superposition of its interseismic motion and the transient post-seismic effects of the 1995 and 2003 earthquakes. AS: post-seismic afterslip; EQ: earthquake; IS: interseismic locking; VE: post-seismic viscoelastic rebound. An educated guess b. Cumulative viscoelastic displacements for the 17-yr-long period 2003.06 to 2020.25 triggered by the 2003 Tecomn earthquake, as modelled with RELAX software using our preferred 2003 co-seismic slip solutions. Figure 4 shows examples of the Omori-like fitting for the horizontal displacement rates at It is movement during an earthauake that breaks pipes, aqueducts and other infrastructure. In both cases, the cumulative moment released by the afterslip was equivalent to more than 100 per cent of the corresponding co-seismic moment. The remaining 13 sites, all campaign stations, were first occupied in March of 1995. 2010; Radiguet etal. The formal velocity uncertainties, which are estimated by TDEFNODE solely from the formal uncertainties in the inverted GPS station positions, are typically less than 1mm yr1. 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. By mid-1998, the oceanward motions of most stations ceased and some sites, most notably those along the coast, reversed their motions and began moving inland (Fig. 2010). 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. Positions are progressively shifted to the right to help visualization. Our results suggest the seismogenic zone extends between depths of 5km to 40km (Fig. Similarly, using Schmitt etal. 2011). The formal uncertainties in the NA-IGS14 angular velocity vector propagate into 1 uncertainties of only 0.03mm yr1 in the north and east components of the velocity for the North America plate relative to IGS14 at the centre of our study area, too small to affect any of the results or interpretations that follow. 14b). I think you re going to see people going down that path we! 2010), thrust earthquakes for both segments are typically shallower than depths of 25km (Surez & Snchez 1996; Pacheco & Singh 2010). (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 data set has been corrected for the viscoelastic effects of the 1995 ColimaJalisco and the 2003 Tecomn earthquakes using m = 15yr for the mantle. The 1995 and 2003 earthquakes strongly influenced horizontal (Fig. Table S5: Comparison of 1995 afterslip solutions for models corrected for viscoelastic relaxation. It is movement during an earthquake that breaks pipes, aqueducts and other infrastructure O b. The latter two processes decay with different characteristic timescales after the earthquakes. (a) Continuous sites: 0.25-yr mean positions. 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. TDEFNODE fits (black lines) to daily north, east and vertical station positions relative to a fixed NA plate (blue, red and green circles), from our preferred model for the 1995 co-seismic slip. Black dots locate the fault nodes where slip is estimated. Dashed lines show the slab contours every 20km. 20 of the main document. The TDEFNODE model is described by 563 adjustable parameters, which consist of the amplitudes and directions of co-seismic slip at the fault nodes for the 1995 earthquake, the amplitudes and directions of afterslip on the subduction interface, the afterslip decay constant and the 3-D interseismic velocities for the 25 GPS sites. Supporting Information Fig. One of the problems facing the Church in the Western world today is the problem posed by the ministry of those who are considered gifted speakers and consequently idolised by the Church. S4). No previous afterslip solution for this earthquake has been estimated, although Schmitt etal. (2). 2006; Pea etal. Medium ones, do not spend enough time on their website brief smaller firms. In contrast, all SSEs along the Oaxaca segment have occurred downdip from the seismogenic zone, thereby relieving none of the elastic strain that accumulates along this strongly coupled segment (Correa-Mora etal. The large afterslip following the 1995 and 2003 earthquakes partially overlapped their rupture zones and extended downdip to depths of 6065km. Intercepts are arbitrary. In the case of COLI, the percentages are 10.0 percent and 18.5 percent). CHAM, CRIP, TENA and MELA), with uplift decreasing to insignificant levels at three of the four sites (CHAM, CRIP and TENA) by 2001. 2013; Sun etal. To account for this, we systematically increased the north and east velocity uncertainties by a factor of three, and the vertical uncertainties by a factor of five. All GPS coordinate time-series were also corrected for equipment-related offsets and other discontinuities not related to earthquakes. Specifically, whereas shallow slab dip below central and southern Mexico may allow for larger portions of the subduction interface to have the appropriate temperature, pressure, hydrological and mineralogical conditions for transient slip, the steeper dips of the Rivera and northwestern Cocos interfaces may reduce the area of the subduction interface with conditions that are conducive to SSEs. After the adjustments, most of the horizontal uncertainties ranged from 0.63.5mm yr1 and vertical uncertainties from 0.94mm yr1. 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. Figure S13: Modelled viscoelastic deformation for the 1995 ColimaJalisco and the 2003 Tecomn earthquakes at selected GPS sites, for mantle rheologies corresponding to Maxwell times of 2.5 (blue), 15 (red) and 40yr (green). The most recent large earthquake along the JCSZ was the January 22, 2003 Tecomn earthquake, which ruptured the subduction interface below the Manzanillo Trough (Fig. 2003; Iglesias etal. The crisscrossing of the nerve fibers from the various . 1.3) and weighted root mean square (wrms) error (eq. The yellow patch is the total estimated aftershock area of the 1932 June 3 and 18 earthquakes (Singh etal.

Data from the GPS sites COLI and INEG for the period 19932001 were provided courtesy of Professor Bertha Mrquez-Aza of the University of Guadalajara ([email protected]). Panels (c) and (d) respectively show the horizontal and vertical site motions predicted by the co-seismic and afterslip solutions from panels (a) and (b) at sites active during the earthquake for panel (c) and sites active between 1995 and 2003 for panel (d). Hutton etal. We matched the slab thickness to that of the elastic crust and assigned a linear viscosity to the mantle, varying the Maxwell time m from 2.5 to 40yr (viscosities from 3.16 1018 Pas to 5.06 1019 Pas for = 40 GPa). Our processing methodology includes constraints on a priori tropospheric hydrostatic and wet delays from Vienna Mapping Function parameters (http://ggosatm.hg.tuwien.ac.at), elevation dependent and azimuthally dependent GPS and satellite antenna phase centre corrections from IGS08 ANTEX files (available via ftp from sideshow.jpl.nasa.gov) and FES2004 corrections for ocean tidal loading (holt.oso.chalmers.se). Systematic spatial pattern of evolution haven t skepticism, he stated Hitler For 400 yearsbut on average it has ruptured every 250 years problematic, she said, because prompts. 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. b. 2005) that we refer to hereafter as the Manzanillo Trough. For each starting model, we calculated synthetic 3-D velocities at the GPS sites and perturbed the synthetic velocities with random noise of 1mm yr1 (1-sigma) for the horizontal components and 2mm yr1 for the vertical. Dashed lines show the slab contours every 20km. The sun and moon exert a gravitational tug on Earth that stretches and compresses crustal rocks. 2002; Marquez-Azua etal. The Mw = 8.0 1995 ColimaJalisco and Mw = 7.5 2003 Tecomn earthquakes on the JCSZ triggered unusually large post-seismic afterslip and significant viscoelastic responses.

It is movement during an earthquake that adds to built up tectonic stress. 4) and vertical (Fig. 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). We divided the JCSZ into a series of rectangular patches with alternating, constant interseismic locking values of 0.0 and 0.5 (upper two panels in each of Supporting Information Figs S2S5). 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. Our results, optimized to fit the post-seismic phase of the 1995 earthquake, which had the largest viscoelastic response, are consistent with mantle viscosities of 0.51.9 1019 Pas (Maxwell times of 415yr), in agreement with similar studies in other subduction zones.
