Same as Fig. Rodríguez M. Synolakis C.E. 1993). More recently, the 2006 Java and 2010 Mentawai earthquakes, both in Indonesia, have qualified as ‘tsunami earthquakes’; the latter could be regarded as an aftershock of the 2007 Bengkulu earthquake. An end-member to this series could be the 1896 Meiji Sanriku earthquake, for which Tanioka & Satake (1996) have argued that the rupture propagated coseismically into the accretionary wedge, with essentially no delay between the two events. 6 for Event III (Model 22.1). Following the work of Newman & Okal (1998), itself based on Boatwright & Choy (1986), we seek to obtain slowness parameters Θ = log10(EE/M0) for Events I, II and III. On the other hand, among the three sequences of Kuril-type tsunami earthquakes, the most variable parameter is the time delay between the main shock and the ‘tsunami earthquake’: 7 d in the 1963 episode, 19 d in 1932 but nearly 2 years in 1973-1975. Although this model produces larger waves than 22.1 and 22.2, they remain smaller than reported.

Same as Fig. The strongest tidal wave registered in Mexico so far reached a height of 10.90 meters. Obviously and unfortunately, the time delay in question would also be the most valuable parameter from a societal standpoint. Another mechanism for the generation of exceptionally large tsunamis after earthquakes is the triggering of submarine landslides. ... El Paso, and southern New Mexico. We also show, on Fig. Having assessed in Section 4 the static moment of Event III at 4 × 1027 dyn cm, we explore several possible geometries for its source. In the case of most aftershocks, we used a constrained depth of 25 km, as suggested in the scenario of a large interplate thrust event. This content is PDF only. Compared to other countries, Tsunamis therefore occur more often than average, but still moderate. We note that both GR′s and EV′s locations fall within our Monte Carlo confidence ellipse. (c) Run-up along coastline, plotted as a function of longitude. (1985) suggested the existence of a Colima seismic gap, which was filled during the later Tecoman earthquake of 2003 January 22 (Yagi et al. Search for other works by this author on: Bulletin of the Seismological Society of America (1985) 75 (5): 1301–1313. Also a comparison of seismograms of 1932 and 1995 earthquakes show great differences. In the first model tested for the main shock, labelled 03.1, we derive a centroid of the rupture by assuming that our relocated epicentral location corresponds to the initiation of the rupture at the deepest boundary of the faulting area. Davies H.L. Note the different scale of the palette in (b). People in southern Mexico woke up when the earth was shaking violently, to find rubble, buildings damaged and without electricity, as a result of the 8.2 magnitude earthquake, which struck at … Then, in Model 22.4, we keep the focal mechanism of the splay fault in Model 22.2, but release it in a sedimentary material featuring a deficient rigidity. Previous studies of the 1932 earthquakes (Espíndola et al. In the case of Event III, all solutions are displaced SSW from the main shock in the vicinity of our relocated solution (19.24°N, 104.34°W), although our confidence ellipses for the three events do intersect. 2, the resulting estimate for the fault length relies entirely on their events 1, 22 and 12. Unfortunately, we faced a number of challenges due to the date of the events (predating, e.g. SE-50, U.S. Dept. For example, during the 1992 Nicaragua event (mb= 5.3; Ms= 7.2), the earthquake was not felt in some coastal communities, whose unprepared population was washed away 40 min later, at a cost of 170 casualties (Satake et al. 5 energy-to-moment ratios for the ‘tsunami earthquakes’ of 1963 October 20 (‘K63’) and 1975 June 10 (‘K75’) that were aftershocks of the regular subduction events of 1963 October 13 (Kanamori 1970) and 1973 June 17, respectively (energy estimates were obtained from the Benioff 1-90 records of their P waves at Pasadena, and their moments were derived from WWSSN records of their mantle Love and Rayleigh waves). Table 2 lists all the records used in this study. The most interesting results are, of course, those for Event III for which, to our best knowledge, no prior computation of seismic moment was reported in the literature. Note the flat spectrum of Event II and the mild frequency dependence for Event I expressing source finiteness. We find an average value Mc= 8.19 ± 0.36 for Event I, corresponding to M0= 1.55 × 1028 dyn cm, in excellent agreement with our one-station estimate (Okal 1992). All these figures are substantially lower than ours, and expectedly so, because the authors worked at higher frequencies, which for this size of source are systematically affected by the destructive interference due to source finiteness (Ben-Menahem 1961; Geller 1976). Relocation of the principal aftershocks, flagged with a a in Table 1. Bilek S.L. In the case of Event II, we could find only one set of usable records, at DBN, which are however excellent and offer a perfectly flat moment featuring no trend with period and yielding M0= 5.2 × 1027 dyn cm. Dixon T. 3, does not stray outside of the 2s window shown as the yellow band. Okal & Synolakis (2004) have shown that because landslides and earthquakes obey different scaling laws, their tsunamis feature characteristically different run-up distributions in the near field. Simulation of Event I′s tsunami under Model 03.1. Numbers refer to Table 1. John Bellini, a geophysicist at the USGS National Earthquake Information Center in Golden, Colorado, said it was the strongest quake since an 8.1 temblor struck the western state of Jalisco in 1932. There is generally more scatter among the published solutions, but once again our confidence ellipse includes EV′s solution and grazes GR′s. Earthquake information. For each event, the values of Mc, the mantle magnitude corrected for focal mechanism (Okal & Talandier 1989), are plotted against frequency, with relevant period and moment scales given along the top and right axes. For Events I and III, the oblique dashed lines are linear regressions of the data sets. EPA-EFE/JORGE NUÑEZ Emergency Services workers inspect the debris of a … Under the circumstances, we assume for Events I and II a mechanism (ϕ= 310°; δ = 14°; λ= 90°) expressing pure subduction along the local plate boundary; this mechanism is also very close to that of the nearby Colima earthquake of 2003 January 22 (ϕ = 308°; δ= 12°; λ = 110°). In this respect, the specific hazard inherent in those anomalous events that are treacherous because they do not carry the natural warning of an impending tsunami in the form of intense shaking, should be emphasized globally as part of tsunami education programs. 11, the maximum run-up increases to 4 m in Manzanillo and 4.5 m in Cuyutlán but remains smaller than reported (note that the color palette used on Figs 11 and 12 differs from that of Figs 6-10). Hayes G. The relocated epicentre of Event I, at 19.65°N, 104.00°W, is compared on Fig. The quake that struck Mexico overnight matches the force of a magnitude 8.1 quake that hit the country on June 3, 1932, roughly 300 miles (500 kilometers) west of Mexico City. S. K. Singh, L. Ponce, S. P. Nishenko; The great Jalisco, Mexico, earthquakes of 1932: Subduction of the Rivera plate. In particular, the catastrophic Event III tsunami can be modelled using the seismically anomalous source derived in Section 4, without the need to invoke a different mechanism such as an underwater landslide. Note again significantly lower wave heights, in agreement with the weaker nature of the tsunami, as compared to Event I. As a result, our simulations remain tentative in an absolute sense, but can be used to compare the relative responses of the coastline to different seismic source scenarios. With an estimated magnitude of 7.6 on the surface wave magnitude scale, a maximum felt intensity of X on the Mercalli intensity scale, the quake destroyed 1,167 houses and caused 275 deaths and 320 injuries.The earthquake was located close to the northern margin of the Tibetan Plateau; this … The parameters L= 150 km, W= 75 km and Δu = 4.5 m are derived from scaling laws (Geller 1976). 12(c), run-up at selected locations along the coastline obtained, on initially dry land, as the elevation above sea level of the point of maximum wave inundation. 2011), we keep a conventional rigidity for this model. 1, at 19.57°N, 104.42°W. Please check your email address / username and password and try again. At 7:18 in the On September 19, 1985, a powerful earthquake strikes Mexico City and leaves 10,000 people dead, 30,000 injured and thousands more homeless. Previous determinations of Event I′s moment include Espíndola ′s (1981) comparative study of surface waves at Uppsala in the 40-70 σ range (1.0 × 1028 dyn cm), Wang ′s (1982) analysis of 50-s surface waves at three European stations (0.9 × 1028 dyn cm) and Singh ′s (1984) body wave modelling at Uppsala and Stuttgart (0.3 × 1028 dyn cm). Because the epicentral distances involved (19.17°, 19.32° and 19.30°, respectively) are significantly shorter than the range of applicability (35° ≤ Δ ≤ 80°) of the distance correction used in the definition of T (Newman & Okal 1998), we use an empirical extension of this correction derived by Ebeling & Okal (2007). Scenario 22.3 is inspired by Lay & Bilek′s (2007) model of a variable, generally deficient, rigidity along the uppermost part of the subduction interplate. Same as Fig. We note that these authors did not carry out a full relocation based on worldwide travel times but rather used a limited number of differential times, such as S-P at regional distances. Although the boundary between the Rivera and Cocos plates is uncertain, there is little doubt that the 1932 earthquakes broke the shallow part of the Rivera subduction zone. These events have relatively small confidence ellipses and as such help provide an estimate of the dimension of rupture. Great magnitude 8.1 earthquake - Jalisco, Mexico, on Friday, 3 June 1932 at 10:36 (GMT) Great magnitude 8.1 earthquake at 15 km depth World earthquake list. 1981; Wang et al. This is confirmed by a deficient energy-to-moment ratio, as derived from high-frequency P waves recorded at Pasadena. You could not be signed in. Unfortunately, the resulting data sets are insufficient to allow a formal inversion, for example, using the Preliminary Determination of Focal Mechanism (PDFM) algorithm (Okal & Reymond 2003). We obtain Θ =-5.20, -5.14 and -6.18, respectively for Events I, II and III. Skanavis V. (1997), ‘tsunami earthquakes’ could occur along the interplate contact with the rupture velocities occurring in a sediment-starved environment and expressing a jagged propagation of the rupture along an irregular contact on the shallowest portions of the plate boundary, the absence of a sedimentary plug allowing the up-dip propagation of the rupture to the ocean floor. Across the Pacific, both the Philippines and New Zealand were on alert for possible tsunamis. greater than the 1995 earthquake. 1). 1 also shows our relocation of Event II, at 19.58°N, 103.84°W, as well as the other estimates for this source. 1 as the circle, at 19.46°N, 104.15°W. Domínguez T. Nicaragua, 1992, -6.47) and comparable to that derived for Event III. along the Pacific coast of Mexico is the plate boundary between the Rivera-Cocos plates and the North America plate (Figure 1). In this section, we simulate the regional tsunamis generated by Events I, II and III based on models of their ruptures derived from the waveform studies of Section 4. 9 for preferred Model 22.4, featuring rupture in a weaker material. We emphasize that, because Ebeling & Okal′s (2007) regional distance corrections were derived empirically in the absence of a rigorous theoretical framework, these values remain tentative in an absolute sense; however, because the epicentral distance is essentially the same for all three earthquakes, the relative values for the three events are robust. This procedure is necessary to allow a run-up computation simulating the interaction with the coastline. The bull′s eye symbol (M) identifies the city of Manzanillo and the solid dot (C) the resort of Cuyutlán. All our results then fit the model for ‘tsunami earthquake’ aftershocks proposed for the Kuril Islands by Fukao in 1979. Papabatu A.K. The resulting displacement field is shown on Fig. The time steps are adjusted for each grid, down to t= 1 σ for the finest one, to satisfy the stability condition of Courant et al. A Ms = 8.2 earthquake on 3 June and its aftershocks of 18 June (Ms = 7.8) were followed by another large (Ms = 6.9) aftershock on 22 June Also, Fig. (1991), which includes a Monte Carlo algorithm injecting Gaussian noise into the data set. This model is particularly suited to the case of ‘tsunami earthquakes’ occurring as aftershocks, where the softer wedge material may have seen a loading by stress transfer from the primary event. We were able to gather on-scale records of the generalized P waves from all three events on the east-west Wood-Anderson seismometer at Pasadena (Fig. The paper was significantly improved by the comments of two anonymous reviewers. 1932-06-03 10:36:56 (UTC) | 19.786°N 103.784°W | 15.0 km depth (1984). These authors used Richter′s (1958) algorithm based on the variation of P-wave residuals with azimuth to derive their own relocation, shown as the square on Fig. We conduct a detailed seismological study of the large Colima, Mexico earthquake of 1932 June 3 and of its aftershocks of June 18 and 22. Following the occurrence of the 2004 Sumatra earthquake in a subduction zone where Ruff & Kanamori′s (1980) paradigm did not predict a megathrust event, Stein and Okal (2007) cautioned that simple tectonic parameters were actually poor predictors of the occurrence of large earthquakes in subduction zones; the present results suggest that the same conclusion could apply to the triggering of ‘tsunami earthquakes’ after large subduction events. We interpret this as an outer-rise intraplate event, which we exclude from the data set of genuine aftershocks defining the extent of rupture. 3, M0 increases regularly and steeply with period on all three available records, gaining close to a factor of 10 between 80 and 200 s. Our empirical regression features a slope of -13.7 logarithmic units per mHz, 2.5 times steeper than for Event I, and clearly shows that the data set transgresses its 2s band. Earthquake's victims rest outside their residences in Juchitan town, Oaxaca, Mexico, Sept. 9, 2017. The resulting values of T (-6.37 and -6.43, respectively) are typical of recent tsunami earthquakes (e.g. A gap of about 60 km remains between the aftershock areas of the 1932 Jalisco and the 1973 Colima earthquakes whose seismic potential is unknown. Historical earthquake in Mexico. Modern relocations show Event III 48 km from Event I in the azimuth N207°E (EV) or 52 km in the azimuth N219°E (this study). Historically, several significant earthquakes have occurred along the southern coast of Mexico. Goodstein J.R. As mentioned by Eissler & McNally (1984), Event I′s entry is missing from the collection of B. Gutenberg′s notepads (Goodstein et al. The 1932 Changma earthquake occurred at 10:04:27 local time on 25 December. Her choice to clothe herself in the garb of a socialite debutante has more than a touch of irony to it. The 1985 earthquake hit near the capital Mexico City, killing thousands and injuring many more. Even the ISS and GR′s locations (constrained to precisions no better than 0.1° and 1/4°, respectively) exhibit similar trends (33 km, N250°E and 55 km, N205°E, respectively). 1932 (4.0) — Slight damage resulted from an earthquake in the Mexia-Wortham area on April 9, 1932. In this general context, the purpose of this paper is to conduct modern seismological studies of the 1932 Manzanillo earthquake series, primarily the main shock (June 3; henceforth Event I), the main aftershock (June 18; Event II) and the ‘tsunami earthquake’ of June 22 (Event III), and to use their results in hydrodynamic simulations to reproduce the main characteristics of the inundations during the two tsunamis of 1932 June 3 and 22. Its run-up was reported to have reached 10 m (Sánchez & Farreras 1993), making it clearly larger than that of the main shock and thus qualifying Event III as a ‘tsunami earthquake’. EMSC (European Mediterranean Seismological Centre) provides real time earthquake information for seismic events with magnitude larger than 5 in the European … Moore C. Newman A.V. In the case of the 1932 Mexican series, we are limited by the availability of adequate records, in particular because the events predate the development of the broad-band ‘1-90’ instruments (available at Pasadena starting in 1937). We use Mansinha & Smylie′s (1971) algorithm to compute the field of static displacement of the ocean bottom resulting from the dislocation, which is then taken as the initial condition, for the numerical simulation, of the deformation of the sea surface. According to Mexico’s National Seismological Service, three of those happened within a nerve-wracking nine-month span in 1902-1903. Kisslinger C. Espíndola J.M. 1982; Eissler & McNally 1984; Singh et al. None of the relocations could resolve hypocentral depth. All bathymetry grids are derived from the GEBCO 0.5-min global data set, the finer ones being simply interpolated from the coarser grid. A study by Mexico's National Seismological Service says Thursday's deadly quake matches the force of a magnitude 8.1 quake that hit the country on June 3, 1932… The simulation uses the Method of Splitting Tsunamis (MOST) code (Titov & Synolakis 1998) that solves the full non-linear equations of hydrodynamics under the shallow-water approximation by finite differences and through the method of alternate steps (Godunov 1959). (1928). 2) in general agreement with our estimate of 140 km. Convers J. Singh S.K. Estimated casualties: 600. 12a) and wave heights reach 7 m (Fig. A third earthquake of 3.0 magnitude occurred in the area at 11:16 a.m. On March 27, four more quakes, including one measured at 3.7 magnitude, occurred in the same area. These records were digitized at a sampling rate t= 0.1 σ and processed through the standard algorithm for the computation of T. A correction is introduced to take into account the use of a single horizontal component. 669 were injured. 4,106 homes were destroyed and a further 3,218 were damaged. 1932-06-03 10:36:56 UTC at 10:36 June 03, 1932 UTC Location: Epicenter at 19.786, -103.784 11.2 km from Las Primaveras [Invernadero] (7.2 miles) Michoacan, Mexico. With a published moment of 1.6 × 10 28 dyn cm (), the great Colima-Jalisco earthquake of 1932 June 3 was one of the largest to strike Mexico since the dawn of instrumental seismology.It resulted in considerable destruction in the city of Manzanillo and generated a … This site uses cookies. 2004). By continuing to use our website, you are agreeing to our, Copyright © 2021 Seismological Society of America. We conduct a detailed seismological study of the large Colima, Mexico earthquake of 1932 June 3 and of its aftershocks of June 18 and 22. Synolakis C.E. Classical examples would include the 1929 Grand Banks, Newfoundland and 1934 Luzon events, for which the existence of the landslides was documented during the repair of telegraphic cables severed by the events (Repetti 1934; Heezen & Ewing 1952). Mikumo T. We show on Fig. However, we emphasize the trend, common to all solutions, in the relative locations of Events III and I. However, a mechanism similar to those used for Events I and II would not modify our main conclusion, namely that Event III features source slowness. Brown A.
