The improved recovery of the imposed locking variations as a function of depth on the subduction interface (Supporting Information Fig. The surgery for both these fractures is technically difficult because of the volume of soft tissue and proneness to complications. (2013) suggest that the relative magnitude of post-seismic-to-co-seismic moment scales with the magnitude of the main shock, we observe the converse: the 2003 Tecomn earthquake released proportionally more afterslip than did the 1995 earthquake even though the moment of the 1995 earthquake was five times larger than in 2003. 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. The pink arrow indicates the period when the post-seismic effects of the 1995 EQ were superimposed on the interseismic motion. 2004; Manea & Manea 2011). Both features of our 1995 afterslip model (i.e. 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). Uncertainties have been omitted for clarity. 2010; Radiguet etal. 14). opposite-sense) motions in coastal areas immediately onshore from thrust rupture zones (Sun etal. For example, the seismic potency estimated in the latter study, P0 = 2.5 1010 m3, where the potency P0 is defined as the estimated seismic moment normalized by the shear modulus (Ben-Menahmen & Singh 1981), differs by only 3 per cent from P0 = 2.43 1010 m3 for this study. The dashed vertical lines mark the time of the 2003 Tecomn earthquake. S7). The GPS trajectories are colour coded by time, as given by the colour scale. Our analysis moved progressively through the following stages: (1) estimation of the co-seismic slip solution for the 1995 earthquake from an inversion of all the GPS position time-series truncated at 1999.0 (Section5.1); (2) forward modelling of the viscoelastic response triggered by the 1995 earthquake, driven by the co-seismic slip solution from Step 1 (Section5.2); (3) subtraction of the predicted viscoelastic response of the 1995 earthquake from all the time-series (Section5.3); (4) estimation of the co-seismic slip solution for the 2003 earthquake from an inversion of all the GPS time-series corrected for the viscoelastic effects of the 1995 earthquake and truncated at 2005.5 (Section5.3); (5) forward modelling of the viscoelastic responses triggered by the 2003 earthquake, driven by the co-seismic slip solutions from Step 4 (Section5.4); (6) subtraction of the predicted viscoelastic responses of the 1995 and 2003 earthquakes from the original GPS time-series through early 2020 (Section5.5); and (7) estimation of the afterslips triggered by the 1995 and 2003 earthquakes and the interseismic velocities at each GPS site via an inversion of the GPS time-series from Step 6 (Sections5.5 and5.6). Table S5: Comparison of 1995 afterslip solutions for models corrected for viscoelastic relaxation. GPS station vertical trajectories for years 2003.082020.00. Our modelling suggests that afterslip in 1995 and 2003 extended all the way downdip to the region of NVT on the Rivera/Cocos subduction interfaces (Fig. 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. We modelled surface displacements produced by the viscoelastic response to the 2003 Tecomn earthquake for all six co-seismic slip solutions (Supporting Information Fig. Dashed vertical lines mark the time of the 1995 and 2003 earthquakes. The yellow patch is the total estimated aftershock area of the 1932 June 3 and 18 earthquakes (Singh etal. Supp_Information_Cosenza-Muralles_etal_2021-I.pdf. Because many more campaign than continuous sites were operating during the early years of this study, when rapid post-seismic deformation after the 1995 ColimaJalisco earthquake occurred, we favoured the models that best fit the early campaign observations. It is movement following an earthquake that continues to break pipes, aqueducts and other infrastructure for weeks and months. 1.4) for all models with viscoelastic relaxation corrections. The seismicity suggests distributed shear across a diffuse RiveraCocos plate boundary (DeMets & Wilson 1997). Lin etal. The inset map shows the site location and 1995 and 2003 earthquake rupture areas. Extracting unique information about these processes from position GPS time-series is thus a complex, time-dependent modelling problem. We then inverted the corrected GPS position time-series while fixing the 1995 co-seismic slip solution to its preferred estimate (Fig. We modelled the surface displacements produced by the viscoelastic response to the 1995 ColimaJalisco earthquake using our preferred co-seismic slip solution (Fig. (1997). 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). 20). Previous authors have considered the same trade-off between afterslip and viscoelastic mantle/crustal responses along subduction zones. S9 and Tables S3 and S4. 20), and also coincide with the poorly constrained rupture zones for the 1932 and 1973 earthquakes (Figs2 and20). S1). 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. 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). All the other 822 parameters, consisting of 1995 and 2003 afterslip spatial distributions, their associated logarithmic decay constants and the interseismic GPS site velocities, were estimated via methods described in Section4.2. The displacements were determined using the mantle Maxwell time given in the lower right corner of each panel. 2004). 2004), 2.3 1020 Nm (Yagi etal. Blue dashed line delimits the 2003 earthquake rupture area from Fig. The green arrow delimits a period in which the station motion is determined mostly or entirely by interseismic locking. 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!

All rights reserved. Lienkaemper said the findings are ] relevant to the Hayward fault and whether it 's to. The horizontal and vertical interseismic site velocities Vij for all six assumed mantle Maxwell times are tabulated in Supporting Information Table S10. 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. Select one: a. Except for the uppermost 5km of the subduction interface, where any slip is poorly resolved, the imposed variations in the interface locking are well recovered (compare the lower two and upper two panels in Supporting Information Fig. Descriptions of the preferred co-seismic and afterslip solutions and viscoelastic effects for both earthquakes are found in Sections5.1 to 5.5. 2015; Wiseman etal. 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. (2007). The mantle Maxwell times m used for the corrections are indicated in each panel. Fault node spacings are 927km along-strike (18.5km on average) and 525km downdip (10.5km on average), located at 5-km depth contours. (a) Continuous sites: 0.25-yr mean positions. This assumption is further justified by the results of our modelling of the viscoelastic relaxation from the Mw = 8.0 1995 earthquake (Section5.2). 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. EQ: earthquake. (2004) and the USGS (stars in Fig. 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. 1 However, these figures do not include the marketing content online, in print, at the movies, in video games, or at school. 2005) that we refer to hereafter as the Manzanillo Trough. 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. (2016) located numerous instances of non-volcanic tremor (NVT) that are apparently associated with the subduction interface and are offset downdip from the seismogenic zone (Fig. The rupture encompasses the gCMT earthquake centroid (Ekstrm etal. We interpret this result as evidence that the input daily site position uncertainties, which are typically 0.70.9mm in the horizontal and 4mm in the vertical components, are undervalued. Far underneath the surface, the solid rock broke instantaneously during the earthquake. Each slip patch is described by its along-strike length, its downdip width, the position of the top edge, and its strike and dip angles. Seismic observations have detected widespread NVT on the subduction interface downdip from the source regions of SSEs and offset downdip from the megathrust earthquake rupture zones (Payero etal. Purple line delimits the 1995 afterslip area as shown in Fig. 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 postseismic observations favor a ramp-flat structure in which the flat angle should be lower than 10. 1) The Theory of Plate Tectonics is . S14). (b) Vertical velocities. 20 of the main document. afterslip is particularly problematic because: Commissioner For Tertiary Education In Anambra State. 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. 21 for m = 8yr). It is movement following an earthquake that continues to break pipes, aqueducts and other infrastructure for weeks and months. Colima at Manzanillo P.S., UNAVCO, GPS/GNSS Observations Dataset, Jalisco 1996, UNAVCO, GPS/GNSS Observations Dataset, Jalisco 1995 03 (March), UNAVCO, GPS/GNSS Observations Dataset, Jalisco 1995 10 (October), UNAVCO, GPS/GNSS Observations Dataset, Jalisco 1997, UNAVCO, GPS/GNSS Observations Dataset, Jalisco 1998, UNAVCO, GPS/GNSS Observations Dataset, Jalisco 1999, UNAVCO, GPS/GNSS Observations Dataset, Jalisco GPS Network - CRIP-Cent. Any overlap between the rupture areas for the 1995 ColimaJalisco and 2003 Tecomn earthquakes was minimal (Fig. 5; Hutton etal. (2007) speculated that the afterslip in 2003 occurred at a downdip location based on an observed reversal in the sense of the co-seismic and post-seismic vertical movements at two coastal sites in the days after the earthquake. 1979), the 1995 Mw = 8.0 ColimaJalisco earthquake and the 2003 Mw = 7.5 Tecomn earthquake (Fig. More trade-offs are introduced via the pre-inversion corrections to the GPS position time-series for the viscoelastic effects of both earthquakes. 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. It inverts campaign and continuous GPS position time-series and other geodetic, seismologic and plate kinematic data to estimate simultaneously the long-term linear (steady) motions of sites and short-term transients such as co-seismic slip, afterslip and slow slip events (McCaffrey 2009). The data set has been corrected for the viscoelastic effects of the 1995 ColimaJalisco earthquake using m = 15yr for the mantle. Lowry etal. 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. 2004), respectively. 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. CuC: Cuyutln canyon. 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. 14a). Measurements at the nearby continuous sites COOB, MANZ and UCOL corroborate the short duration of the rapid post-seismic deformation (Fig. This hypothesis is further supported by numerical models of the earthquake cycle of megathrust earthquakes, in which the occurrence of large earthquakes followed by afterslip that propagates downdip into the slow-slip region weakens the fault segment and releases strain energy, thus suppressing SSEs for up to a few decades (Shi etal. c. The fits of the time-dependent model with m = 15yr are good overall (Fig. Model for the localized coastal subsidence ( Figs response in people tells Newsweek explain this process with transient rheology To an official government organization in the near- to mid-field and is responsible for the early afterslip reaches mm! 15 sites refers to the use of the sites active during the earthquake exclusively. 2001). 2004). S11 shows the modelled displacements at selected sites. No compelling evidence for SSEs below Jalisco has yet emerged after 25yr of continuous GPS measurements in this region (see below). Using Hutton etal. 2012; Bedford etal. (2002). Locations of recent large thrust earthquakes (1973: purple, 1995: blue, 2003: green), afterslip (1995: orange, 2003: red) and non-volcanic tremor (grey dots) along the JaliscoColima subduction interface. Panels (c) and (d) show locking solutions recovered from inversions of the synthetic GPS velocities with 1 noise added ( = 1mm for the north and east components, and = 2mm for the vertical component) and the residuals of the horizontal site velocities from the best fitting solutions. The Cocos plate, on the other hand, subducts at 51 2mm yr1 along the trench south and east of the Colima Graben (Fig. Afterslip is particularly problematic because: It is movement following an earthquake that continues to break pipes, aqueducts and other infrastructure for weeks and months 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 interseismic GPS site velocities, which are described and modelled by CM21-II, are summarized briefly in Section5.6. 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. 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. 2004), and epicentres estimated by Yagi etal. (2004; shown by the red lines in Fig. 2016). 2014a, 2016; Bekaert etal. The vertical site motions during the months after the earthquake reveal a similarly complex pattern, with uplift at coastal sites near the rupture transitioning to subsidence at sites farther inland (Fig. 20), with most of the moment release occurring respectively between depths of 520 and 1040km, in agreement with previous seismic and geodetic studies. 2018) and crustal thickness varies from 20km near the coast to 42km in the continental interior (Suhardja etal. (b) Continuous sites installed near the Nevado de Colima volcano. 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. The same TDEFNODE inversion indicates that afterslip from the 2003 earthquake was concentrated primarily along and directly downdip from the 2003 earthquake rupture zone (Fig. 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. ", It is impossible to tell when the Hayward Fault will rupture. 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! s(x,w,t)=AX(x)W(w)S(t)
Hutton etal. Black dots locate the fault nodes where slip is estimated. Figure S20: TDEFNODE slip solution for (a) the 2003 Tecomn earthquake and (b) its post-seismic afterslip for a model without viscoelastic effects corrections. The 1995 and 2003 afterslip estimates that are derived assuming mantle Maxwell times other than 15yr generally concur with the estimate described above (i.e. Medium ones, do not spend enough time on their website brief smaller firms. 2010). 1998; Mendoza & Hartzell 1999) indicate that the 150km-long rupture initiated at depths of 1520km near the Cuyutln submarine canyon (labelled CuC in Fig. 2012; Graham etal. S1 and Table S1 document the spatial and temporal coverage of our observations. 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. No previous afterslip solution for this earthquake has been estimated, although Schmitt etal. 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. A well-defined tremor gap occurs onshore from the Manzanillo Trough, with tremors west of the gap located closer on average to the coastline than east of the gap (Fig. As well as being a stimulant, caffein The rapid post-seismic uplift rates decreased with time at the four sites nearest the rupture zone (i.e. (2007) but differ at some locations in the vertical component (Supporting Information Fig. 9b and Supporting Information Table S9) and consistent with deep afterslip reported by Hutton 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. We evaluated the sensitivity of the 2003 co-seismic slip solutions to the length of the post-seismic interval spanned by our data, ranging from as little as 0.5yr to as long as 4.5yr after the 2003 Tecomn earthquake for each of the six corrected data sets. 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. 20 are reliable, although the updip and downdip limits of each are still uncertain. Dashed lines show the slab contours (extended from Hayes etal. The smaller scatter after early 2003 was caused by a change in the GPS equipment.
