1932 mexico earthquake

Simulations are carried out for a time window lasting 2 hr after origin time. The second earthquake caused as few as 3 or as many as 52 deaths. earthquakes today - recent and latest earthquakes, earthquake map and earthquake information. 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. 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 This approximation, classical in tsunami modelling, is justified by the fact that any seismic rupture, including a slow one characteristic of a ‘tsunami earthquake’, remains hypersonic with respect to the propagation velocities of tsunamis (Okal & Synolakis 2003). 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. 2011), the recent Mentawai disaster (700 killed) illustrates the shortcomings of a natural warning relying only on shaking ‘intensity’, the challenges of educating populations to the perception of shaking ‘duration’ remaining of course formidable (Fritz et al. Taylor F.W. Okal & Kirby (2002) and later López & Okal (2006) have shown that this approach can be applied to paper records from historical events. Please check your email address / username and password and try again. The 1932 Changma earthquake occurred at 10:04:27 local time on 25 December. 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). Scawthron C. Synolakis C.E. 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. Event II, the largest aftershock on 1932 June 18, caused additional damage, especially in the hinterland locations of Colima and Guadalajara. 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. Relocation of the principal aftershocks, flagged with a a in Table 1. 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. 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. 1932-06-03 10:36:56 (UTC) | 19.786°N 103.784°W | 15.0 km depth Seismic records used in this study. Dixon T. Pacheco J. Previous studies of the 1932 earthquakes (Espíndola et al. We note that both GR′s and EV′s locations fall within our Monte Carlo confidence ellipse. It’s undercut with grit and attitude by her cigarette-in-hand. Suwargadi B. 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). ‘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. Synolakis C.E. The common scale allows for direct comparison of the three events, clearly exposing Event III′s deficiency in high frequencies. It is remarkable that Fukao′s (1979) model, derived for the Kuril province, can be exported to a subduction zone with significantly different tectonic characteristics: a much younger age and a slower convergence rate. Note the flat spectrum of Event II and the mild frequency dependence for Event I expressing source finiteness. 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). The parameters L= 150 km, W= 75 km and Δu = 4.5 m are derived from scaling laws (Geller 1976). 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. 1, at 19.57°N, 104.42°W. 7 shows that the simulated tsunami amplitude falls to 1.5 m in Manzanillo, substantially lower than observed.

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. Earthquake information for europe. 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. 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). We used S times only for depleted data sets involving small events, for which their contribution is crucial to the performance of the algorithm. 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. For each event, the estimated energy EE is plotted against the seismic moment M0 in logarithmic units. Aftershocks of the 7.8 quake Colima, Mexico, 18 June 1932 10:12 GMT More info Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. This site uses cookies. Her choice to clothe herself in the garb of a socialite debutante has more than a touch of irony to it. The largest observed earthquake in the region was a magnitude 8.6 in Oaxaca in 1787. Davies H.L. Silver E.A. Latest Earthquakes in the world. We also show, on Fig. 2011). 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 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. Domínguez T. Okal E.A. 3, does not stray outside of the 2s window shown as the yellow band. (c) Run-up along coastline, plotted as a function of longitude. All our results then fit the model for ‘tsunami earthquake’ aftershocks proposed for the Kuril Islands by Fukao in 1979. Sweet S. 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… In general, two tectonic contexts have been proposed for the occurrence of ‘tsunami earthquakes’. This estimate is half the 280 km proposed by Singh et al. 10 shows that the results are changed only marginally and that it would not predict the reported widespread inundation. Earthquake's victims rest outside their residences in Juchitan town, Oaxaca, Mexico, Sept. 9, 2017. 1981; Wang et al. Five of those were assigned magnitudes MPAS ≥ 6 by GR. In this respect, it is most reminiscent of the sequences of 1963 October and 1973-1975, both in the Kuril Islands. As expected, the combination of a smaller source and an inland epicentre (as confirmed by significant destruction in the hinterland) results in a much smaller tsunami with simulated amplitudes around Manzanillo of 1-1.5 m (Fig. This scenario, which requires a sedimentary input into the subduction zone, could apply to the 2010 Mentawai aftershock of the 2007 Bengkulu earthquake (Newman et al. 6 for Model 22.3, featuring a deficient rigidity along a gently dipping fault plane. 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. The bull′s eye symbol (M) identifies the city of Manzanillo and the solid dot (C) the resort of Cuyutlán. Tappin D.R. 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. 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). Skanavis V. 2011), we keep a conventional rigidity for this model. 8.1 magnitude earthquake. 1982; Eissler & McNally 1984; Singh et al. 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. (1928). Epicentral distances are computed for Event I and rounded to the nearest degree. Relocation of Events I (red), II (blue) and III (green). Table 2 lists all the records used in this study. 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. 12b). Hayes G. (a) Field of vertical displacement of the ocean floor, computed using Mansinha & Smylie′s (1971) algorithm. Compared to other countries, Tsunamis therefore occur more often than average, but still moderate. 1 also shows our relocation of Event II, at 19.58°N, 103.84°W, as well as the other estimates for this source. What controls the lateral variation of large earthquake occurrence along the Japan trench? Kahlo positions herself atop a stone which straddles the border. 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. 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 … 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 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. Borrero J.C. Rodríguez M. Synolakis C.E. By contrast, in a second scenario, originally described by Tanioka et al. You could not be signed in. Kisslinger C. Espíndola J.M. 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. 2011) and possibly to the Hikurangi, New Zealand event of 1947 March 25 (Doser & Webb 2003). The locked zone at this plate interface ruptured in two stages in June 1932. Unfortunately, we faced a number of challenges due to the date of the events (predating, e.g. Fig. The 1985 earthquake hit near the capital Mexico City, killing thousands and injuring many more.

Kanamori H. All bathymetry grids are derived from the GEBCO 0.5-min global data set, the finer ones being simply interpolated from the coarser grid. Fig. (a) and (b) Same as Fig. The ISS location is shown as a downward triangle at 19.2°N, 104.2°W, whereas GR′s is shown as an upward triangle at 19.5°N, 104.25°W. In the case of Event III, the strong slope, reaching outside of the confidence interval, expresses the intrinsic slowness of the source. Mikumo T. 5 shows that Events I and II feature T values characteristic of large interplate thrust earthquakes whereas Event III exhibits an energy-to-moment ratio typical of ‘tsunami earthquakes’ such as the 1992 Nicaragua event. The paper was significantly improved by the comments of two anonymous reviewers. 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. 9 for Model 22.2, featuring a steeper fault dip. 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’. Numbers refer to Table 1. This is the exact geometry favoured by Fukao (1979) to explain the Kuril ‘tsunami earthquakes’ of 1963 October 20 and 1975 June 10. Brown A. All relevant parameters are listed in Table 3. 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. ... El Paso, and southern New Mexico. 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). There is no evidence of events occurring SE of MNZ even up to 1 1/2 yr after the first main shock. Also, Fig. 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 … 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. MOST has been extensively validated through comparisons with laboratory and field data, per standard international protocols; full details can be found in Synolakis (2003). 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. 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). 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'. 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. 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. 9 shows that the wave heights remain moderate, not exceeding 2.5-3 m in the area of Manzanillo and Cuyutlán. Simulation of Event I′s tsunami under Model 03.1. The 1932 Mexican sequence constitutes a classical example of a regular main shock triggering, within a few weeks’ time, a slow ‘tsunami earthquake’. Also a comparison of seismograms of 1932 and 1995 earthquakes show great differences. 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. The strongest tidal wave registered in Mexico so far reached a height of 10.90 meters. (An additional element of diversity is the occurrence of many foreshocks including several large ones during the 1963 sequence.) Having assessed in Section 4 the static moment of Event III at 4 × 1027 dyn cm, we explore several possible geometries for its source. greater than the 1995 earthquake. 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. Event I on 1932 June 3 resulted in severe destruction in Manzanillo and adjoining areas with upwards of 400 casualties. In summary, Model 03.1 best describes the effects of the tsunami on Manzanillo and its vicinity. S. K. Singh, L. Ponce, S. P. Nishenko; The great Jalisco, Mexico, earthquakes of 1932: Subduction of the Rivera plate. Although this model shows a marginal increase in wave heights, it still cannot account for the devastating nature of the tsunami. Kanamori H. 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. 8), once again in agreement with the reported values (Sánchez & Farreras 1993). along the Pacific coast of Mexico is the plate boundary between the Rivera-Cocos plates and the North America plate (Figure 1). 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. 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. We obtain Θ =-5.20, -5.14 and -6.18, respectively for Events I, II and III. Rupture across arc segment and plate boundaries in the 1 April 2007 Solomons earthquake, Seismic strain release along the Middle America Trench, Mexico, Intraplate seismicity of the Pacific Basin, 1913-1988, Source rupture process of the Tecoman, Colima, Mexico earthquake of January 22, 2003, determined by joint inversion of teleseismic body wave and near source data, © The Authors Geophysical Journal International © 2011 RAS, Induced polarization of volcanic rocks. 2, the resulting estimate for the fault length relies entirely on their events 1, 22 and 12. In turn, such events can be treacherous for the local populations who feel them at most as weak tremors and are thus deprived of a natural warning for the impending tsunami. 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 … 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. 161 people were killed in the 1932 Ierissos earthquake. Wei Y. 6 for Event III (Model 22.1). 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. Note that the ISS did not locate the event, but simply assumed a common epicentre with Event I. ‘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. Note the different scale of the palette in (b). 6310 km 2 (=2436 sqare miles) as a first-order estimate. This content is PDF only. 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. As mentioned by Eissler & McNally (1984), Event I′s entry is missing from the collection of B. Gutenberg′s notepads (Goodstein et al. World earthquake list. 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. Same as Fig. 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. Historical earthquake in Mexico. 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). We conclude that Fukao′s (1979) model involving rupture along a splay fault satisfactorily explains the available data. Yamamoto J. On September 19, 1985, a powerful earthquake strikes Mexico City and leaves 10,000 people dead, 30,000 injured and thousands more homeless. Same as Fig. Note significantly lower wave heights. 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. The latter is our Event 23 (1932 August 24; b in Table 1), which clearly occurred farther south and east with a moderate-sized confidence ellipse, not reaching the coastline. Those eight ‘major’ aftershocks are plotted with their confidence ellipses on Fig. Events triggering landslides are generally not considered ‘tsunami earthquakes’ as their sources do not exhibit seismically anomalous behaviour. The vertical static displacement from the earthquake grows to a maximum of 3.2 m (Fig. 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. 3 regroups our results for all three events. Nicaragua, 1992, -6.47) and comparable to that derived for Event III. 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). 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. Both were aftershocks of larger events (on 1963 October 13 and 1973 June 17, respectively) whose tsunamis could be considered as regular. Although this model produces larger waves than 22.1 and 22.2, they remain smaller than reported. Hornbach M. Convers J. Singh S.K. 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. This model would predict a smaller, rather than larger, tsunami than for Event I. Solid dots form a background of typical values from recent sources. 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. 4. Please click on the PDF icon to access. Pranantyo I.R. For events in the 1930s, we give this noise a standard deviation σG= 5 s. Results are given in Table 1. According to Mexico’s National Seismological Service, three of those happened within a nerve-wracking nine-month span in 1902-1903. 1993). As shown on Fig. You do not currently have access to this article. Among their conclusions, Singh et al. The scale of the palette is common with Fig. 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. On their Fig. Borrero J.C. Note that a regression of the full data set of Mc values with frequency, shown as the blue dashed line on Fig. Notwithstanding this reservation, Fig. Note again significantly lower wave heights, in agreement with the weaker nature of the tsunami, as compared to Event I.
