2012; Bedford etal. 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. 2007; Correa-Mora etal. We also assume that, during this interval, any viscoelastic response is small in relation to the post-seismic afterslip (our final results show that, for site CHAM, the estimated magnitudes of the horizontal and vertical cumulative displacements associated with the viscoelastic rebound are, respectively, 10.0 percent and 8.3 percent that of the cumulative afterslip. 2). 2007), in agreement with the seismic estimates referenced above. The Cuyutln canyon along with the Coahuayana canyon (CoC in Fig. 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). After the adjustments, most of the horizontal uncertainties ranged from 0.63.5mm yr1 and vertical uncertainties from 0.94mm yr1. Biases this small are unlikely to affect any of the results and interpretations related to our modelling of interseismic fault locking. 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. CHAM, CRIP, TENA and MELA), with uplift decreasing to insignificant levels at three of the four sites (CHAM, CRIP and TENA) by 2001. Viscoelastic relaxation due to the 2003 earthquake (Fig. Dashed vertical lines mark the time of the earthquake. The top of the domain is the Earths crust. 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. AUTA, AYUT and GUFI) increased, whereas most inland sites subsided. This material is based on GPS data and services provided by the GAGE Facility, operated by UNAVCO, Inc. and by the TLALOCNet GPS network operated by Servicio de Geodesia Satelital (SGS; Cabral-Cano etal. 2004; Yoshioka etal. Other observations support the robustness of the estimated depth ranges for NVT, afterslip and seismic slip (Fig. (1997). 2008; Radiguet etal. 2008, 2009; Vergnolle etal. Intercepts are arbitrary. Both features of our 1995 afterslip model (i.e. Search for other works by this author on: Departamento de Estudios Socio Urbanos, Universidad de Guadalajara, Instituto de Geofsica, Universidad Nacional Autnoma de Mxico, Ciudad Universitaria, Caltech Seismological Laboratory, California Institute of Technology, Department of Geology, Portland State University, In TDEFNODE, the temporal and spatial distributions of slip on a fault during an event are described by, $$\begin{equation*} (2) includes numerous fitting trade-offs between the 1995 and 2003 earthquake co-seismic and afterslip solutions and the interseismic GPS site velocities Vij. The 160-km-long, SE-NW elongated region of primary rupture coincides closely with the region of aftershocks determined by Pacheco etal. 2011; Abbott & Brudzinski 2015; Hayes etal. 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. 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. Locations of the GPS stations used in this study. Westward-directed postseismic seafloor displacements may be due flow via low-temperature, plastic creep within the lower half of a Pacific lithosphere weakened by plate bending. Our geodetically derived co-seismic moment, 1.84 1020 Nm (Mw = 7.4), is close to seismologic estimates of Mo = 2.0 1020 Nm (Ekstrm etal. 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. EQ: earthquake. 20). Problematic cognitions are thought to maintain problematic gaming behaviors. 2006; Pea etal. The preferred model, which optimizes the fit to data from several years of rapid post-seismic deformation after the larger 1995 earthquake, has a mantle Maxwell time of 15yr (viscosity of 2 1019 Pas), although upper-mantle viscosities as low as 5 1018 Pas cannot be excluded. 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. 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. Research on gamers has identified several attitudes and beliefs associated with excessive playing behavior. The dashed vertical lines mark the time of the 2003 Tecomn earthquake. They predicted that the afterslip at the deep roots of faults deformation most, Freed, 2005 ) in this work, we expect its afterslip to last longer Has warned that people in the seismic sequence in May 2012 was characterized by two which! The __ __ __ __ carries sensory input from the skin of the lateral 2/3rds of the hand, palm side and dorsum of fingers 2-3. median nerve cutaneous branch. S3). (a) Continuous sites: 0.25-yr mean positions. 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. The interseismic GPS site velocities, which are described and modelled by CM21-II, are summarized briefly in Section5.6. We analysed all of the GPS code-phase data with releases 6.3 and 6.4 of the GIPSY software suite from the Jet Propulsion Laboratory (JPL). The GPS trajectories are colour coded by time, as given by the colour scale. 1985). 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. 2004) and 1.88 1020 Nm (Quintanar etal. 20) support this hypothesis. 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. 2013; Graham etal. 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). 1995; Cabral-Cano etal. Black dots locate the fault nodes where slip is estimated. Perfettini and Avouac, 2004, Hsu . 1997), respectively. 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). Dashed lines show the slab contours every 20km. 2012); 5 1018 Pas and 3 1019 Pas respectively for a low-viscosity wedge and the long term mantle viscosity (Trubienko etal. 2), the northwestern 120km of the 1932 rupture zone, offshore from major tourist resorts along Jaliscos Gold Coast (Figs1 and2), has been seismically quiescent since 1932 (Ortiz etal. Previous authors have considered the same trade-off between afterslip and viscoelastic mantle/crustal responses along subduction zones. (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. Fig. (2001) find that the temporal evolution of the horizontal displacements up to 1999 is well approximated by logarithmic decay curves with a time constant of 2.43.7d, consistent with afterslip on the subduction interface. 2014; Wiseman etal.

Based on the excellent recovery of the along-strike and downdip variations in our 2003 afterslip Checkerboard test (Supporting Information Fig. 3) for our best model is 13.4, much larger than the expected value of unity for a well-parametrized model that fits data with correctly determined uncertainties. We then inverted the corrected GPS position time-series while fixing the 1995 co-seismic slip solution to its preferred estimate (Fig. 20 of the main document. Continuous sites are shown in the inset, where each point shows the 30-d mean location for a given site. 14a) and the seismologic slip solutions referenced above is reinforced by the checkerboard test most applicable for the 2003 earthquake (Supporting Information Fig. Afterslip is particularly problematic because: Find out more from Tom Brocher and here: https://www.google.com/amp/s/ucrtoday.ucr.edu/38678/amp Select one: a. Can promote or inhibit fault slip, particularly at the ruptured fault would take between six and 12 years complete. ] Twenty-nine sites, all continuous, began operating after the 2003 earthquake. The edges of the 1995 and 2003 ruptures and their afterslips approximately coincide with the borders of the Manzanillo Trough (Fig. Global distribution of volcanoes b. introduction-to-social-work-and-social-welfare ; 0 Answers. 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. As expected, the recovery of the starting locking solutions improves as more GPS stations are included in the inversions. 6a). \textrm {wrms}=\left[\left(\sum _N \frac{r^2}{\sigma ^2}\right) \Bigg/\left(\sum _N \frac{1}{\sigma ^2} \right) \right]^{1/2} Extracting unique information about these processes from position GPS time-series is thus a complex, time-dependent modelling problem. Only stations that where operating during the earthquake are shown. 1985). Based on results from static modelling of the newly estimated interseismic motions (CM21-II), we adopt a best viscosity of 1.9 1019 Pas (m = 15yr). 2010). 2017); and (9) viscoelastic layer thicknesses and depths different than those assumed for our analysis (i.e. The TDEFNODE misfits F (eq. Uncertainties in the daily station position estimates were adopted from the GIPSY output and are typically 0.6mm in longitude, 0.5mm in latitude and 2.5mm in elevation. 2). No previous afterslip solution for this earthquake has been estimated, although Schmitt etal. The smaller scatter after early 2003 was caused by a change in the GPS equipment. 2019, and figs 11 and 16). b. 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. 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. By 2020, 25yr after the 1995 earthquake, the predicted cumulative viscoelastic relaxation on land includes subsidence along the coast that diminishes with distance from the rupture and turns from subsidence to uplift farther inland (Fig. (2001) from their modelling of the first few years of post-seismic data, and with the results from Marquez-Azua etal. 2007). 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. The January 30, 1973 earthquake (Fig. 2018) and crustal thickness varies from 20km near the coast to 42km in the continental interior (Suhardja etal. 1997). 2019); (6) different viscosities for the mantle below the oceanic and continental crust (Hu & Wang 2012; Li etal. Alternatively, if frictional conditions do permit SSEs and post-seismic afterslip to occur along the same parts of a subduction interface, as appears to be true along the Oaxaca segment (Graham etal. 1997; Escobedo etal. S2 to Supporting Information Figs S4 and S5). Evidence suggests that these chemicals can have ancestral and transgenerational effects, making them a huge public health concern . The vertical displacements associated with afterslip transition from uplift onshore from the rupture to minor subsidence at sites father inland (Fig. Black dots locate the fault nodes where slip is estimated. Synonym Discussion of problematic. 1997; Hutton etal. The principal difference between the 2003 earthquake co-seismic and afterslip solutions (Figs14a andb, respectively) is that the latter is located 1020km farther downdip than the former. 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). Global distribution of earthquakes c. Glob Campaign sites are shown in the main figure. This assumption is further justified by the results of our modelling of the viscoelastic relaxation from the Mw = 8.0 1995 earthquake (Section5.2). To continue reading login or create an account. Figure S3: Checkerboard tests for the JaliscoColima subduction zone. 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 location of NVT in this segment correlates with zones of slab dehydration with isotherms of 400500 C (Manea & Manea 2011; Manea etal. Table1 summarizes the depths of these different processes. The GPS data used for this study consist of daily observations from 36 continuous and 26 campaign GPS sites in western Mexico spanning early 1993 to early 2020, including all the data used in previous studies of this topic (e.g. 2007), was the first large rupture of the JCSZ segment since 1932. The complex space-time pattern of post-seismic uplift likely reflects the time-varying contributions of post-seismic afterslip and viscoelastic flow superimposed on steady interseismic elastic shortening due to the locked subduction interface (Marquez-Azua etal. (2) Early afterslip shows no evidence of a delayed nucleation or acceleration phase, where instead fault patches transition to immediate deceleration following rupture that is consistent with frictional relaxation under steady state conditions with dependence only on the sliding velocity. The wrms misfits are 3.1 to 9.5mm in the horizontal position components at continuous sites COLI and INEG and average 3.3mm at the 23 campaign GPS sites. 2012; Graham etal. Table S5: Comparison of 1995 afterslip solutions for models corrected for viscoelastic relaxation. Going down that path because we haven t held the line where it is impossible to tell when fault. Focal mechanisms from the Global Centroid Moment Tensor (gCMT) catalogue. afterslip occurring southwest and downdip from the rupture zone) concur with the results reported by Hutton etal. Geometry of the computational domain and rheological structure in modelling with RELAX. Modelling of waveforms from local and teleseismic body wave data suggest that this rupture initiated at a depth of 20km and propagated up- and downdip (Yagi etal. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. But not all sections of the fault are the same. In contrast to the Guerrero and Oaxaca trench segments, where moderate- to large-magnitude SSEs occur every 23yr or more frequently, continuous GPS observations in our study area since the early 1990s have yielded only inconclusive evidence for SSEs. 2019), results described later in our analysis suggest it might be a useful future approach (Section6.4). 1997). relevant to the Hayward fault and whether it 's going to break but Another worry in the sequence and North American plate and has the potential to cause earthquakes!, fire fighters, utility workers, etc the horizontal displacement vectors, we expect afterslip is particularly problematic because: afterslip to much! (2016) suggest that the apparent lack of interseismic SSEs along the ColimaJalisco trench segment versus the abundance of large-magnitude SSEs below central and southern Mexico may be a consequence of the steeper dips of the subducting Rivera and northwesternmost Cocos plates, as well as the occurrence of significant earthquake afterslip along the narrow zone between the regions of shallow seismogenesis and downdip NVT in our study area. Here, we invert 25yr of data to separate the long-term steady interseismic motion of each site from the transient deformation components. EQ: earthquake. 1997; Hutton etal. ", It is impossible to tell when the Hayward Fault will rupture. 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. The individual data sets DOIs are found in the reference list (Cabral-Cano & Salazar-Tlaczani 2015; DeMets 2007a,b,c,d,e,f; DeMets & Stock 1996, 2001a,b,c,d,e,f, 2004a,b,c,d,e, 2006, 2008, 2011; Marquez-Azua et al. 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). The vertical motions of GPS sites in our study area (Fig. (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.
