1932 mexico earthquake

The 1932 Mexican sequence constitutes a classical example of a regular main shock triggering, within a few weeks’ time, a slow ‘tsunami earthquake’. 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). This suggests that Event III has a static moment of approximately 4 × 1027 dyn cm and definitely identifies it as an event featuring an anomalously slow source, confirming its nature as a ‘tsunami earthquake’. Solid dots form a background of typical values from recent sources. Note the different scale of the palette in (b). With a published moment of 1.6 × 1028 dyn cm (Okal 1992), the great Colima-Jalisco earthquake of 1932 June 3 was one of the largest to strike Mexico since the dawn of instrumental seismology. Sweet S. 3, does not stray outside of the 2s window shown as the yellow band. Introduction The great Colima-Jalisco, Mexico earthquake … Unfortunately, we faced a number of challenges due to the date of the events (predating, e.g. 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). (a) Field of vertical displacement of the ocean floor, computed using Mansinha & Smylie′s (1971) algorithm. The similarity between the Kuril and Mexican sequences also extends to the moment ratios between the main shock and the ‘tsunami earthquake’, whose values (6.3 in 1932, 12.5 in 1963 and 7.5 in 1973-1975) are generally comparable. Note that a regression of the full data set of Mc values with frequency, shown as the blue dashed line on Fig. ... El Paso, and southern New Mexico. For each event, the estimated energy EE is plotted against the seismic moment M0 in logarithmic units. Based on the work of Boatwright & Choy (1986), Newman & Okal (1998) have proposed a modern rendition of the mb:Ms discriminant, in the form of the parameter Θ = log10(EE/M0), where EE is the seismic energy radiated into the body waves, estimated without knowledge of focal mechanism and exact depth, and M0 the seismic moment. 10 shows that the results are changed only marginally and that it would not predict the reported widespread inundation. Domínguez T. The relocated epicentre of Event I, at 19.65°N, 104.00°W, is compared on Fig. In general, two tectonic contexts have been proposed for the occurrence of ‘tsunami earthquakes’. Kanamori H. 6 for Model 03.2. This is confirmed by a deficient energy-to-moment ratio, as derived from high-frequency P waves recorded at Pasadena. Fig. 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. 4,106 homes were destroyed and a further 3,218 were damaged. Seismic records used in this study. 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. Qiang Q. We were able to gather a number of historical seismograms of Events I, II and III for the purpose of computing spectral amplitudes of long-period surface waves and examining the energy contained in teleseismic P waves. The effects of Events I, II and III and especially of their tsunamis are summarized, for example, by Sánchez & Farreras (1993), based primarily on Mexican newspaper accounts. We relocated systematically the main shock and all 28 apparent aftershocks occurring in 1932, using the data listed by the International Seismological Summary (ISS) and the interactive iterative method of Wysession et al. Note that the fault length is in good agreement with the extent of the well-located aftershocks plotted on Fig. Agriculture & Commerce, Catâlogo de tsunamis (Maremotos) en la Costa Occidental de Mexico [Catalog of tsunamis on the Western coast of Mexico], World Data Center A Pub. However, the Friday earthquake matched the force of a magnitude 8.1 quake that hit the country on June 3, 1932, roughly 300 miles west of Mexico City. Detail showing Kahlo’s self-portrait Frida Kahlo was as talented at self-projection as she was at introspection. Skanavis V. Our results may help in quantifying seismic potential of tectonically similar areas such as the Juan de Fuca subduction zone in the NW United States. (c) Run-up along coastline, plotted as a function of longitude. The 1932 Jalisco earthquakes began on June 3 at 10:36 UTC with a megathrust event that registered 8.2 on the moment magnitude scale.With a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale, at least 400 deaths were caused in Mexico and neighboring Guatemala.It was the first of a series of seismic events that affected parts of western Mexico … 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. 1 with various other estimates. This scenario would apply in Nicaragua and Java (Polet & Kanamori 2000). Historical earthquake in Mexico. Kisslinger C. Espíndola J.M. It generated a minor tsunami starting with a leading depression, but which did not rise over 1 m. GR assigned it MPAS= 7.9. Although its location on the interplate contact would be generally similar to that of the 2010 Mentawai, Sumatra ‘tsunami earthquake’ (Newman et al. 1 as the circle, at 19.46°N, 104.15°W. 1981; Wang et al. 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. Note that Event III is systematically offset about 50 km to the SSW of Event I. For each event, we use scaling laws (Geller 1976) to interpret the static values of the seismic moment M0 in terms of fault length L, fault width W and seismic slip Δu. It generated a tsunami featuring a leading depression followed by an inundation with run-up reaching 3 m. Event I was assigned a magnitude MPAS= 8.1 by Gutenberg & Richter (1954, hereafter GR). 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). 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). In 1932, a M 8.4 thrust earthquake struck in the region of Jalisco, several hundred kilometers to the northwest of the June 23rd event. 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. 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. 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. 161 people were killed in the 1932 Ierissos earthquake. 2002). The present computations use three nested grids, the coarsest one covering a total area of 330 000 km2 and the finest one, shown on Figs 6-11, featuring a sampling of 0.1 nautical mile (0.185 km). Frohlich C. Jennings P.C. In the case of Event III, the strong slope, reaching outside of the confidence interval, expresses the intrinsic slowness of the source. 1932 (4.0) — Slight damage resulted from an earthquake in the Mexia-Wortham area on April 9, 1932. 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 The slow character of a seismic source, such as a ‘tsunami earthquake’, can also be assessed by comparing the high- and low-frequency parts of its source spectrum. In short, this model simulates a tsunami smaller than that of Event I and thus, fails to account for the much larger wave heights observed. The diagonal lines feature constant T, the solid one being the theoretical value (-4.90) expected from scaling laws. 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. Same as Fig. ‘Tsunami earthquakes’ have parameters T typically 1-1.5 logarithmic units below the theoretical value (-4.90) expected from the application of seismic scaling laws. 6 for Event II (Model 18.1). Same as Fig. Event III is a typical ‘tsunami earthquake’, with a slowness parameter Θ =-6.18, more than one logarithmic unit less than predicted by scaling laws. The US Geological Survey reported the earthquake's magnitude as 8.1, making it the biggest earthquake in Mexico since 1932 Castro R. 12(b) shows inundation of the land spit separating the ocean from the Cuyutlán lagoons, in accordance with the description reported in local newspapers (El Excelsior 1932) and summarized by Sánchez & Farreras (1993). In 1932, Mexico was hit by the Jalisco earthquake with a magnitude of 8.1. Bilek S.L. 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). Earthquake information for europe. (An additional element of diversity is the occurrence of many foreshocks including several large ones during the 1963 sequence.) The latter (Event III) generated a tsunami more devastating than that of the main shock despite much smaller seismic magnitudes, thus qualifying as a so-called ‘tsunami earthquake’. Villaseñor A. 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. 2, the resulting estimate for the fault length relies entirely on their events 1, 22 and 12. (b) Field of maximum wave heights during a 2-hr time window after origin time. Although this model produces larger waves than 22.1 and 22.2, they remain smaller than reported. Brown A. For each event, our relocated epicentre is shown as the large star (surrounded by its Monte Carlo confidence ellipse), the ISS location as the inverted triangle, GR′s estimate as the upward triangle, EV′s relocation as the circle and in the case of Event I, Eissler & McNally′s (1984) estimate as the square. For each available surface wave, we compute spectral amplitudes at mantle periods (50 ≤ T ≤ 250 s), which we interpret as mantle magnitudes Mm in the formalism of Okal & Talandier (1989). Despite a slightly different mechanism that does not require rupturing on a splay fault (Newman et al. By contrast, Event III, on 1932 June 22, that GR assessed at only MPAS= 6.9, generated a catastrophic tsunami that wiped out a 25 km stretch of coastline and in particular, destroyed the resort city of Cuyutlán, killing at least 75 people. 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. Kanamori′s (1972) original paper was based on two events: the 1896 Sanriku earthquake and the 1946 Aleutian one. Note: This seismic event was followed by a 7.5-8.1 magnitude earthquake in the same general area (the second shock was closer to Colima) on 18 June 1932 at 10:12 UT. On their Fig. Lee W.H.K. This procedure is necessary to allow a run-up computation simulating the interaction with the coastline. 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. The second earthquake caused as few as 3 or as many as 52 deaths. 1993). 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. 6(b). Lin L. Two other earthquakes of magnitude 8 or over were recorded in the 20 th century—a magnitude 8.1 in 1932 and a magnitude 8 in 1985. Based on the long-period seismic moments derived in this study, our hydrodynamic simulations reproduce the main characteristic of the tsunamis as reported in historical chronicles: a run-up of about 3 m concentrated in the bay of Manzanillo during Event I, a much more benign tsunami during Event II and a catastrophic inundation after Event III with run-ups reaching 7 m; the latter is explained by setting the rupture on a splay fault in weaker, presumably sedimentary, material in the wedge of the subduction system under the exact scenario proposed by Fukao (1979) in the Kuril Islands. This site uses cookies. We also explored, in Model 03.2, the possibility of a source displaced WNW along the coastline, as suggested by Singh ′s (1985) model of an extended rupture and Eissler & McNally′s (1984) relocation significantly westwards of the other solutions (Fig. Estimated magnitude: 7.8-8.4. Epicenters and Locations of the Latest Quakes Near Santa Anita, Jalisco, Mexico 8.0 magnitude and above - Before 1932-06-03 10:36:56 UTC Earthquake … Its relationship to the main shock fits Fukao′s (1979) model and is particularly reminiscent of that of the Kuril duo on 1963 October 13 and 20. Depth: 15 km Note again significantly lower wave heights, in agreement with the weaker nature of the tsunami, as compared to Event I. Moore C. Newman A.V. 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’. 11, but differs from Figs 6-10. Hayes G. Suwargadi B. However, we emphasize the trend, common to all solutions, in the relative locations of Events III and I. Bull′s eye symbols denote ‘tsunami earthquakes’, all featuring Θ =-5.8 (N: Nicaragua, 1992; J: Java, 1994 and 2006; M: Mentawai, 2010; K: Kuril, 1963 and 1975; C: Chimbote, Peru, 1996; T: Tonga, 1982; A46: Aleutian, 1946; S04: Sumatra, 2004; for the latter, both the CMT and normal mode moments are shown). This content is PDF only. 1982; Eissler & McNally 1984; Singh et al. ‘Tsunami earthquakes’ are characterized by a slow rupture, as slow as approximately 1 km s-1 (Polet & Kanamori 2000; López & Okal 2006), which leads to a destructive interference of the high-frequency component of their spectrum, expressed, for example, as a strong mb:Ms anomaly. S. K. Singh, L. Ponce, S. P. Nishenko; The great Jalisco, Mexico, earthquakes of 1932: Subduction of the Rivera plate. The resulting displacement field is shown on Fig. doi: We have analyzed seismograms of the 3 June 1932 (Ms = 8.2) and the 18 June 1932 (Ms = 7.8) Jalisco earthquakes and their aftershocks at Manzanillo (MNZ), Guadalajara (GUM), and Tacubaya (TAC). Summary of energy-to-moment ratios for a data set of large recent earthquakes (adapted from Newman & Okal 1998; López & Okal 2006; Okal et al. EPA-EFE/JORGE NUÑEZ Emergency Services workers inspect the debris of a … The aftershocks locations, the first motions at MNZ, and the isoseismic maps of the two main shocks strongly suggest that: (a) the 3 June 1932 earthquake initiated NW of but close to MNZ and propagated NW for an estimated length of rupture of 220 km; (b) the 18 June 1932 earthquake nucleated SW of MNZ (offshore) and perhaps ruptured a length of about 60 km; … 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. The parameters L= 150 km, W= 75 km and Δu = 4.5 m are derived from scaling laws (Geller 1976). 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. Earthquake's victims rest outside their residences in Juchitan town, Oaxaca, Mexico, Sept. 9, 2017. You do not currently have access to this article. Note significantly lower wave heights. It seems that the 1995 event is not a repeat of either June 3 or June 18, 1932 earthquakes. 2. 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 Dixon T. Engdahl E.R. 1). Pacheco J. Link to Wikipedia biography Fig. Numbers refer to Table 1. Although this model shows a marginal increase in wave heights, it still cannot account for the devastating nature of the tsunami. What controls the lateral variation of large earthquake occurrence along the Japan trench? The latter (Event III) generated a tsunami more devastating than that of the main shock despite much smaller seismic magnitudes, thus qualifying as a so-called 'tsunami earthquake'. SE-50, U.S. Dept. There is a slight growth of moment with period due to the effect of source finiteness at higher frequencies (Ben-Menahem 1961) with an average value of 2.4 × 1028 dyn cm beyond 150 σ that we propose as the static value of M0 for Event I. 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. 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). 2 and can be used to obtain an estimate of the length of rupture of the main shock, their relocated epicentres spreading over 140 km parallel to the coastline. of Commerce, Tsunami field survey of the 1992 Nicaragua earthquake, The great Jalisco, Mexico, earthquakes of 1932: subduction of the Rivera plate, Ultra-long period seismic study of the December 2004 Indian Ocean earthquake and implications for regional tectonics and the subduction process, The slump origin of the 1998 Papua New Guinea tsunami, An algorithm for automated tsunami warning in French Polynesia, based on mantle magnitudes, Fault parameters of the 1896 Sanriku tsunami earthquake estimated from tsunami numerical modeling. Events triggering landslides are generally not considered ‘tsunami earthquakes’ as their sources do not exhibit seismically anomalous behaviour. 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. 2011) and possibly to the Hikurangi, New Zealand event of 1947 March 25 (Doser & Webb 2003). Relocation based on published arrival times … greater than the 1995 earthquake. In Model 22.1, we consider the case of a regular earthquake, obeying scaling laws, but simply located up-dip from the main shock. Same as Fig. (1985) suggested the existence of a Colima seismic gap, which was filled during the later Tecoman earthquake of 2003 January 22 (Yagi et al. Taylor F.W. Event II, the largest aftershock on 1932 June 18, caused additional damage, especially in the hinterland locations of Colima and Guadalajara. Note that the ISS did not locate the event, but simply assumed a common epicentre with Event I. The 1998 tsunami in Papua New Guinea is also generally described as resulting from a landslide triggered by the seismic event with a delay of 13 min (Synolakis et al. The resulting values of T (-6.37 and -6.43, respectively) are typical of recent tsunami earthquakes (e.g. Briggs R.W. Isobaths identify the location of the trench and suggest that Event 23 (square, with dotted ellipse), flagged with a b in Table 1, is an outer rise earthquake. For Event III, we assume a steeper dip, representative of faulting along a splay fault in the accretionary wedge that will be our preferred model. 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 … Although Talandier & Okal (1989) further identified the Tonga earthquake of 1982 December 19 as a ‘tsunami earthquake’, it was not until the decade of the 1990s that interest in this matter was revived due to the occurrence of three events, in Nicaragua (1992 September 02), Java (1994 June 02) and Chimbote, Peru (1996 February 21). 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. Mantle magnitude analysis of the low-frequency surface waves from Events I, II and III. They also noted that Event I′s rupture had to extend across the boundary between the Rivera and Cocos plates, under either Reid′s (1976) or Eissler & McNally′s (1984) plate geometries, indicating that such boundaries along subduction systems cannot serve as barriers to the rupture of a very large event, an idea later confirmed by Taylor et al. Havskov J. Fritz H.M. A detailed seismological study of the 1932 sequence in Manzanillo and in particular of Events I, II and III, confirms that the latter occurred up-dip of the main shock and that it featured source slowness resulting in a growth of moment with period and in a deficiency of high frequencies in its source spectrum. 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. 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). 9 shows that the wave heights remain moderate, not exceeding 2.5-3 m in the area of Manzanillo and Cuyutlán. 6(a) and a close-up of the wave heights in Manzanillo and its vicinity on Fig. 12a) and wave heights reach 7 m (Fig. Please check your email address / username and password and try again. Reyes G. Oxford University Press is a department of the University of Oxford. By contrast, in a second scenario, originally described by Tanioka et al. 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. Mikumo T. Those eight ‘major’ aftershocks are plotted with their confidence ellipses on Fig. 12b). We note that both GR′s and EV′s locations fall within our Monte Carlo confidence ellipse. There is generally more scatter among the published solutions, but once again our confidence ellipse includes EV′s solution and grazes GR′s. Near-field hydrodynamic simulations show that the effects of the main shock′s tsunami are well modelled by a standard seismic source, whereas the stronger tsunami from Event III can be modelled by rupture along a splay fault in a mechanically deficient material.
