Fig. 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. 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. It shares the focal geometry of Model 22.1, but features a lower rigidity, and hence an enhanced slip, with a slightly elongated more ‘ribbon-like’ fault geometry. Bardet J.-P. Across the Pacific, both the Philippines and New Zealand were on alert for possible tsunamis. 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. Although this model shows a marginal increase in wave heights, it still cannot account for the devastating nature of the tsunami. 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. 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. 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. Search for other works by this author on: Bulletin of the Seismological Society of America (1985) 75 (5): 1301–1313. 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. Davies H.L. Note the different scale of the palette in (b). Those eight ‘major’ aftershocks are plotted with their confidence ellipses on Fig. Same as Fig. (b) Field of maximum wave heights during a 2-hr time window after origin time. Table 2 lists all the records used in this study. This site uses cookies. 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. 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. 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). Despite a slightly different mechanism that does not require rupturing on a splay fault (Newman et al. Our results show maximum amplitudes on the order of 3.5 m in the bay of MNZ, in general agreement with the descriptions compiled by Sánchez & Farreras (1993), and lesser values in Cuyutlán. 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. 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. 12a) and wave heights reach 7 m (Fig. Event II, the largest aftershock on 1932 June 18, caused additional damage, especially in the hinterland locations of Colima and Guadalajara. 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. 1 as the circle, at 19.46°N, 104.15°W. Bulletin of the Seismological Society of America ; 75 (5): 1301–1313. The central dashed line and shaded area are the average value and 2s confidence interval, respectively. You could not be signed in. Among the 29 earthquakes listed on Table 1, we earmark with a a eight events which have generally better locations, as evidenced by smaller confidence ellipses. This content is PDF only. Goodstein J.R. She uses her Christian name ‘Carmen’ and her husband’s surname as an ironic po… Relocation of Events I (red), II (blue) and III (green). 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 … Kanamori′s (1972) original paper was based on two events: the 1896 Sanriku earthquake and the 1946 Aleutian one. 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. Qiang Q. 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. 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). 3, does not stray outside of the 2s window shown as the yellow band. 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. In Model 22.1, we consider the case of a regular earthquake, obeying scaling laws, but simply located up-dip from the main shock. Note that a regression of the full data set of Mc values with frequency, shown as the blue dashed line on Fig. For events in the 1930s, we give this noise a standard deviation σG= 5 s. Results are given in Table 1. 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). 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. What makes the event truly remarkable is the occurrence, 19 d later, of an aftershock that generated an even more devastating tsunami, despite a clearly smaller conventional magnitude and seismic moment. 1 with various other estimates. Emile A. Okal, José C. Borrero, The ‘tsunami earthquake’ of 1932 June 22 in Manzanillo, Mexico: seismological study and tsunami simulations, Geophysical Journal International, Volume 187, Issue 3, December 2011, Pages 1443–1459, https://doi.org/10.1111/j.1365-246X.2011.05199.x. 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. Mikumo T. It’s undercut with grit and attitude by her cigarette-in-hand. Seismic records used in this study. Same as Fig. As shown on Fig. This is the exact geometry favoured by Fukao (1979) to explain the Kuril ‘tsunami earthquakes’ of 1963 October 20 and 1975 June 10. EMSC (European Mediterranean Seismological Centre) provides real time earthquake information for seismic events with magnitude larger than 5 in the European … The analysis of the spectral amplitude of mantle surface waves yields low-frequency moments of 24, 5.2 and 4 times 1027 dyn cm, respectively, with Event III featuring a moment growing with period, which expresses the source slowness characteristic of ‘tsunami earthquakes’. 1). 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 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 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. Briggs R.W. Kanamori H. The 1985 earthquake hit near the capital Mexico City, killing thousands and injuring many more. The largest observed earthquake in the region was a magnitude 8.6 in Oaxaca in 1787. This is confirmed by a deficient energy-to-moment ratio, as derived from high-frequency P waves recorded at Pasadena. (1985) used a combination of differential S-P and L-P travel times and of first motion polarities at the local station MNZ and the regional stations GUM and TAC (Tacubaya), in support of Eissler & McNally′s (1984) solution. 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. Reyes G. Oxford University Press is a department of the University of Oxford. Historical newspaper articles were compiled and translated in 2005 by Rachel Ryskin as part of an internship at Northwestern University. Reexamination of arrival time data for the 1932 Jalisco earthquake yields an epicenter at 19.57°N, 104.42°W, close to the boundary zone inferred from these two earthquakes. 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'. All relevant parameters are listed in Table 3. The second earthquake caused as few as 3 or as many as 52 deaths. ‘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.

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. As shown on Fig. 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 … We used S times only for depleted data sets involving small events, for which their contribution is crucial to the performance of the algorithm. Events triggering landslides are generally not considered ‘tsunami earthquakes’ as their sources do not exhibit seismically anomalous behaviour. We are grateful to Ota Kulhánek, James Dewey, Brian Mitchell and Bernard Dost for access to historical seismograms. Frohlich C. The inscription reads, ‘Carmen Rivera Painted Her Portrait 1932’. Latest Earthquakes in the world. the development of H. Benioff′s broad-band ‘1-90’ seismometers), the significant difference in size between Events I and III (which can preclude a direct comparison, with Event III hardly emerging from the noise on Wiechert seismograms), and other unfortunate occurrences (the records being changed or the presence of obvious non-linearities). SE-50, U.S. Dept. 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. Note that the ISS did not locate the event, but simply assumed a common epicentre with Event I. We obtain Θ =-5.20, -5.14 and -6.18, respectively for Events I, II and III. 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. Note again significantly lower wave heights, in agreement with the weaker nature of the tsunami, as compared to Event I. Domínguez T. Note inundation of Cuyutlán land spits and run-up reaching 7 m. See text for details. A tsunami was reported which destroyed a … Moore C. Newman A.V. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Note the flat spectrum of Event II and the mild frequency dependence for Event I expressing source finiteness. 2) in general agreement with our estimate of 140 km. This procedure is necessary to allow a run-up computation simulating the interaction with the coastline. Simulation of Event I′s tsunami under Model 03.1. It seems that the 1995 event is not a repeat of either June 3 or June 18, 1932 earthquakes. This qualifies that aftershock as a so-called ‘tsunami earthquake’, a class of events defined by Kanamori (1972) as generating tsunamis of much greater amplitude than suggested by their seismic magnitudes, especially conventional ones. However, we emphasize the trend, common to all solutions, in the relative locations of Events III and I. Also, Fig. Chen W.-F. 6 for Event III (Model 22.1). Her choice to clothe herself in the garb of a socialite debutante has more than a touch of irony to it. 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. Unlike seismic intensity, which measures the strength of shaking and varies according to distance from the quake and other factors, the magnitude is intended to measure the intrinsic size of an earthquake. S. K. Singh, L. Ponce, S. P. Nishenko; The great Jalisco, Mexico, earthquakes of 1932: Subduction of the Rivera plate. 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. Note that the fault length is in good agreement with the extent of the well-located aftershocks plotted on Fig. Simulations are carried out for a time window lasting 2 hr after origin time. 2011). 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; and (c) the width of rupture was approximately 80 km. Kanamori H. 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. The resulting displacement field is shown on Fig. (a) Field of vertical displacement of the ocean floor, computed using Mansinha & Smylie′s (1971) algorithm. All this evidence strongly suggests that Event III occurred about 50 km seawards of the main shock, in a geometry which would be compatible with rupturing either at the very top of the interplate contact, or along a splay fault located in an accretionary wedge inside the North American Plate. We conclude that the possibility that the 1932 Jalisco earthquake broke the northernmost section of the Cocos‐North American plate interface, as opposed to the Rivera‐North American plate interface, cannot be … Note that Event III is systematically offset about 50 km to the SSW of Event I. Note significantly lower wave heights. 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 … 8), once again in agreement with the reported values (Sánchez & Farreras 1993). Tick marks indicate minutes. 9 for preferred Model 22.4, featuring rupture in a weaker material. Pacheco J. Papabatu A.K. 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… 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. 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. 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. Estimated casualties: 600. Both were aftershocks of larger events (on 1963 October 13 and 1973 June 17, respectively) whose tsunamis could be considered as regular. 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. Okal E.A. These events have relatively small confidence ellipses and as such help provide an estimate of the dimension of rupture. 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). Detail showing Kahlo’s self-portrait Frida Kahlo was as talented at self-projection as she was at introspection. There is no evidence of events occurring SE of MNZ even up to 1 1/2 yr after the first main shock. Skanavis V. In Fukao′s (1979) model, they occur on a splay fault developing above the interplate contact into a sedimentary wedge offering inferior mechanical properties and hence a reduced velocity of propagation of the seismic rupture. 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. 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. A study by Mexico's National Seismological Service says that quake is believed to have killed about 400 people, causing severe damage around the port of Manzanillo. 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. The significant difference in wave height and run-up between Models 22.2, 22.3 and 22.4 constitutes a numerical illustration of Okal′s (1988) theoretical results, showing that rupture in a ‘sedimentary’ layer, that is, a structure with deficient rigidity, enhances the excitation of tsunamis relative to seismic surface waves, especially for a 45°-thrust geometry, thereby explaining the properties of ‘tsunami earthquakes’ under Fukao′s (1979) model. Jennings P.C. Convers J. Singh S.K. 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). 669 were injured. 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). In general, two tectonic contexts have been proposed for the occurrence of ‘tsunami earthquakes’. Mantle magnitude analysis of the low-frequency surface waves from Events I, II and III. 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. Epicentral distances are computed for Event I and rounded to the nearest degree. 9 for Model 22.2, featuring a steeper fault dip. The common scale allows for direct comparison of the three events, clearly exposing Event III′s deficiency in high frequencies. 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. Estimated magnitude: 7.8-8.4. There is generally more scatter among the published solutions, but once again our confidence ellipse includes EV′s solution and grazes GR′s. 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. 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. In 1932, Mexico was hit by the Jalisco earthquake with a magnitude of 8.1. Pranantyo I.R. We interpret this as an outer-rise intraplate event, which we exclude from the data set of genuine aftershocks defining the extent of rupture. Tsunamis in Mexico In a total of 24 tidal waves classified as a tsunami since 1732 a total of 91 people died in Mexico. The bull′s eye symbol (M) identifies the city of Manzanillo and the solid dot (C) the resort of Cuyutlán. (1985) suggested the existence of a Colima seismic gap, which was filled during the later Tecoman earthquake of 2003 January 22 (Yagi et al. 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. The 1932 Mexican sequence constitutes a classical example of a regular main shock triggering, within a few weeks’ time, a slow ‘tsunami earthquake’. 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). Bilek S.L. 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). World earthquake list. 161 people were killed in the 1932 Ierissos earthquake. 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. Engdahl E.R. In this respect, it is most reminiscent of the sequences of 1963 October and 1973-1975, both in the Kuril Islands. The 1932 events are shown as the squares (Events I and II, regular T) and the triangle (Event III, deficient T; ‘tsunami earthquake’). 1932 (4.0) — Slight damage resulted from an earthquake in the Mexia-Wortham area on April 9, 1932. Relocation based on published arrival times … 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 … 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. 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). Among their conclusions, Singh et al. 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; … 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 diagonal lines feature constant T, the solid one being the theoretical value (-4.90) expected from scaling laws. 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. In particular, we address the question of a Rivera-Cocos boundary.There have been several large historic earthquakes in the coastal areas of the Mexican states Colima and Jalisco, but the last large event was in June 1932 (the 1932 Jalisco earthquake, M s = 8.1). 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. Also a comparison of seismograms of 1932 and 1995 earthquakes show great differences. All our results then fit the model for ‘tsunami earthquake’ aftershocks proposed for the Kuril Islands by Fukao in 1979. By contrast, in a second scenario, originally described by Tanioka et al. Villaseñor A. 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). The 1932 Changma earthquake occurred at 10:04:27 local time on 25 December. ‘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. 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. 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.
