Notwithstanding this reservation, Fig. Fig. It seems that the 1995 event is not a repeat of either June 3 or June 18, 1932 earthquakes. Nicaragua, 1992, -6.47) and comparable to that derived for Event III. Meltzner A. Taylor F.W. In a variation to this model, Bilek & Lay (1999) and Lay & Bilek (2007) have proposed that the slowness of the slip release could be due to the existence of a zone of reduced rigidity along the interplate contact, itself resulting from the ingestion, compaction and dehydration of sediments along its uppermost part. 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. 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’. (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 vertical static displacement from the earthquake grows to a maximum of 3.2 m (Fig. 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. Parameters of rupture models used in tsunami simulations. 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. As shown on Fig. 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'. Reyes G. Oxford University Press is a department of the University of Oxford. 1982; Eissler & McNally 1984; Singh et al. 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’. This content is PDF only. Events triggering landslides are generally not considered ‘tsunami earthquakes’ as their sources do not exhibit seismically anomalous behaviour. Bilek S.L. 9 for Model 22.2, featuring a steeper fault dip. This is the exact geometry favoured by Fukao (1979) to explain the Kuril ‘tsunami earthquakes’ of 1963 October 20 and 1975 June 10. 1 with various other estimates. Seismic records used in this study. We also show, on Fig. Another mechanism for the generation of exceptionally large tsunamis after earthquakes is the triggering of submarine landslides. 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). 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. 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. Sweet S. Note again significantly lower wave heights, in agreement with the weaker nature of the tsunami, as compared to Event I. Earthquake's victims rest outside their residences in Juchitan town, Oaxaca, Mexico, Sept. 9, 2017. It’s undercut with grit and attitude by her cigarette-in-hand. The central dashed line and shaded area are the average value and 2s confidence interval, respectively. 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. Kahlo positions herself atop a stone which straddles the border. These events have relatively small confidence ellipses and as such help provide an estimate of the dimension of rupture. Billy D. Yagi Y. Same as Fig. (1991), which includes a Monte Carlo algorithm injecting Gaussian noise into the data set. Note that the ISS did not locate the event, but simply assumed a common epicentre with Event I. She uses her Christian name ‘Carmen’ and her husband’s surname as an ironic po… 1 as the circle, at 19.46°N, 104.15°W. 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. 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 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). Qiang Q. Engdahl E.R. 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). 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. 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. 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. In Model 22.1, we consider the case of a regular earthquake, obeying scaling laws, but simply located up-dip from the main shock. 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). 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 … Run-up reaches 7 m in the bay of Manzanillo and 6-7 m further east in Cuyutlán. 6(b). ‘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. Okal & Kirby (2002) and later López & Okal (2006) have shown that this approach can be applied to paper records from historical events. 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). Earthquake information. Same as Fig. 2002). 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. Fig. 4). Records of Events I, II and III on the west-east component of the 6-s Wood-Anderson torsion seismometer at Pasadena. The parameters L= 150 km, W= 75 km and Δu = 4.5 m are derived from scaling laws (Geller 1976). 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. Tsunamis in Mexico In a total of 24 tidal waves classified as a tsunami since 1732 a total of 91 people died in Mexico. 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. earthquakes today - recent and latest earthquakes, earthquake map and earthquake information. Historically, several significant earthquakes have occurred along the southern coast of Mexico. 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. All relevant parameters are listed in Table 3. (1985) suggested the existence of a Colima seismic gap, which was filled during the later Tecoman earthquake of 2003 January 22 (Yagi et al. 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. 6310 km 2 (=2436 sqare miles) as a first-order estimate. 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 … 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. This procedure is necessary to allow a run-up computation simulating the interaction with the coastline. This variability in delay before the ‘tsunami earthquake’ expresses the non-linear nature of the stress transfer outside of the rupturing area of the main shock. Across the Pacific, both the Philippines and New Zealand were on alert for possible tsunamis. 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. 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. 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. 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. Estimated magnitude: 7.8-8.4. 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. This is confirmed by a deficient energy-to-moment ratio, as derived from high-frequency P waves recorded at Pasadena. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. 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. 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. Historical newspaper articles were compiled and translated in 2005 by Rachel Ryskin as part of an internship at Northwestern University. In general, two tectonic contexts have been proposed for the occurrence of ‘tsunami earthquakes’. Tappin D.R. Simulations are carried out for a time window lasting 2 hr after origin time. Lee W.H.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… Bulletin of the Seismological Society of America ; 75 (5): 1301–1313. Tanioka & Satake (1996) have suggested that it may also apply to the 1896 Sanriku event, where the faulting would have deviated into the wedge at the end of the rupture. 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 inscription reads, ‘Carmen Rivera Painted Her Portrait 1932’. 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.

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). 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. It generated a minor tsunami starting with a leading depression, but which did not rise over 1 m. GR assigned it MPAS= 7.9. 3 regroups our results for all three events. 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. Both were aftershocks of larger events (on 1963 October 13 and 1973 June 17, respectively) whose tsunamis could be considered as regular. Wei Y. 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). Synolakis C.E. We used S times only for depleted data sets involving small events, for which their contribution is crucial to the performance of the algorithm. Depth: 15 km 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. The diagonal lines feature constant T, the solid one being the theoretical value (-4.90) expected from scaling laws. Note that a regression of the full data set of Mc values with frequency, shown as the blue dashed line on Fig. Also a comparison of seismograms of 1932 and 1995 earthquakes show great differences. (1984). 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. 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. However, we emphasize the trend, common to all solutions, in the relative locations of Events III and I. Please check your email address / username and password and try again. Convers J. Singh S.K. 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). 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. 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. This scenario would apply in Nicaragua and Java (Polet & Kanamori 2000). Search for other works by this author on: Bulletin of the Seismological Society of America (1985) 75 (5): 1301–1313. 9 shows that the wave heights remain moderate, not exceeding 2.5-3 m in the area of Manzanillo and Cuyutlán. 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 Pacheco J. Relocation of the principal aftershocks, flagged with a a in Table 1. 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. You could not be signed in. 2011). In summary, Model 03.1 best describes the effects of the tsunami on Manzanillo and its vicinity. Note significantly lower wave heights. Singh S.K. Estimated casualties: 600. Event I on 1932 June 3 resulted in severe destruction in Manzanillo and adjoining areas with upwards of 400 casualties. 10 shows that the results are changed only marginally and that it would not predict the reported widespread inundation. The resulting displacement field is shown on Fig. Villaseñor A. Moore C. Newman A.V. 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°). 6 for Model 22.3, featuring a deficient rigidity along a gently dipping fault plane. 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. 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. In the case of Event III, the strong slope, reaching outside of the confidence interval, expresses the intrinsic slowness of the source. Castro R. 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. 6(a) and a close-up of the wave heights in Manzanillo and its vicinity on Fig. 1980), so the details of his relocation remain unknown. S. K. Singh, L. Ponce, S. P. Nishenko; The great Jalisco, Mexico, earthquakes of 1932: Subduction of the Rivera plate. 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’. The relocated epicentre of Event I, at 19.65°N, 104.00°W, is compared on Fig. According to Mexico’s National Seismological Service, three of those happened within a nerve-wracking nine-month span in 1902-1903. 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. Lee W.H.K. Briggs R.W. There is no evidence of events occurring SE of MNZ even up to 1 1/2 yr after the first main shock. The scale of the palette is common with Fig. 1981; Wang et al. 12a) and wave heights reach 7 m (Fig. Although this model shows a marginal increase in wave heights, it still cannot account for the devastating nature of the tsunami. 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.

Note that the fault length is in good agreement with the extent of the well-located aftershocks plotted on Fig. 12b). 6 for Event II (Model 18.1). We note that both GR′s and EV′s locations fall within our Monte Carlo confidence ellipse. 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. 2004). EPA-EFE/JORGE NUÑEZ Emergency Services workers inspect the debris of a … 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. Kanamori H. 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. The 1932 Mexican sequence constitutes a classical example of a regular main shock triggering, within a few weeks’ time, a slow ‘tsunami earthquake’. 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’. Skanavis V.
