In 1905, two M ~ 8 continental strike-slip earthquakes occurred along the Bulnay fault system, in the northwestern part of Mongolia. Nevertheless, the important mass of the Wiechert (1000 kg) limits its impact. The 1905 Tsetserleg earthquake occurred in or near the Tsetserleg Sum of Khvsgl Province in Mongolia on 9 July 1905. You can help Wikipedia by expanding it. Indeed, this criterion produces artificial symmetry and is even more doubtful for surface waves, because it perturbs the dispersion. The segments activated during the Bolnay earthquake are clearly visible on the satellite images, whereas those of the Tsetserleg event are more difficult to identify (Okal 1977). [6], Lasting damage of the earthquake can be seen in the Mongolia special of the Amazon Prime motoring show The Grand Tour.[7]. When the first gap is preceded by only few seconds of signal, the quality of the prediction is limited. Vetterling W.T. The Bolnai earthquake is believed to be a strike-slip rupture of a branch of the Bolnai Fault, extending about 300[3] to 375[4] km along the fault, and possibly an additional 80km of the Teregtiin Fault. Calais et al. What is their source history? The sign (-) is used when the writing arm is displaced to the north or the east. To determine the unknown parameters, we either inverted each of them, or we tested a set of a priori values, by using the Nabelek (1984) program. This catastrophic event in 1905 was an exception. Main active faults in Mongolia and the large earthquakes of the XX century (after Schlupp 1996). However, several earthquakes have been observed in the region at the base of the crust, down to 50 km (Chen & Molnar 1983; Nelson et al. Starting at 22 s after the nucleation, it improves the P, SH and SV waveforms. For the P waves, we obtained good signals at Jena and Uppsala. (b) Source function of the Tsetserleg earthquake with an eastward rupture propagation. Khovd (28.2 miles), 1990-06-14 12:47:28 UTC Please check your email address / username and password and try again. We do not allow fault azimuth to vary more than 10 from the observed surface rupture and the slip or dip angles more than 20. A land area in parts of Mongolia, China, and Russia, covering as much as two million square miles, was affected by these events and people experienced the shaking from east to west over a distance of 1,500 miles. Craven J.A. On the other hand, it propagated to the west along a N80 structure with left lateral strike-slip until its junction with the Bolnay fault. You can help Wikipedia by expanding it. There are few records of the immediate effects of the earthquake due to the remoteness of Mongolia in 1905. For periods less than half the natural period of the pendulum, the impact of solid friction becomes very small. 38.2 km from A local stress tensor in the Tsetserleg area is proposed from surface ruptures. Historical seismograms are being used more frequently now, due to the recent efforts to organize the collections, and to digitize the old records (Ferrari 2000; Michelini et al. at 16:35 December 17, 1938 UTC, Location: The SH component, at Goettingen and Uppsala, are poorly explained after 80 s. Considering only the known surface ruptures, it could not be modelled and neither another kind of wave arrivals, nor anisotropy can, up to now, explain it. On July 9, 1905, an earthquake of magnitude 8.4 occurred in the Gobi-Altai region of southwestern Mongolia, close to the Chinese border. 1993). This is a list of earthquakes in 1905. A left lateral movement characterizes its northeastern part with a reverse component dipping to the northwest. Amarjargal S. Bulletin of the Seismological Society of America (2015) 105 (1): 7293. Epicenter at 46.938, 89.399 33.2 km from Central Mongolia. The t* values considered are 1 s for P waves and 4 s for S waves. We have 2.6 105 in the case of the Bolnay and Gobi-Altay earthquakes (Mongolia, 4 December 1957, Ritz et al. at 18:21 December 22, 1906 UTC, Location: Additionally, each one of these events gave rise to fault movements as big as twenty feet and rupture lengths of several hundred miles. Epicenter at 37.645, 102.489 Trampert J.. Zorin Y.A. The problem being non-linear, we cannot quantify exactly the effect of friction. Teukolsky S.A. Artemyev A.A. The value of the arm shift is not measured during the recording, and it must be deduced. Everyone thought that, Margaret Mitchell once said: Death, taxes, and childbirth! Then the seismogenic zone could be also thick, probably around 2030 km. The source duration was 115 s. The moment magnitude Mw varies between 8.3 and 8.5. Gao S.S., Oxford University Press is a department of the University of Oxford. Synthetic Love wave seismograms for a series of reasonable models of the catastrophic earthquakes of July 1905 in Mongolia are generated and compared to observed data, to help constrain the source parameters suggested from older field reports. Bourls D.L. 1985; Baljinnyam et al. 2003). Aviles C.A. Dezember 1905. 2003). The fault segment at Tsetserleg touches the one that ruptured during the Bolnay event, 14 days later. 2001; Petit et al. For the July 23 event, as the surface ruptures along the Bolnay fault are quite pure strike-slip and very linear, we allowed a freedom of only 5 on the direction and 6 on the slip angle permitting a maximal vertical movement of 1 m. The amplitude of the source time function, the scalar seismic moment, the delay of each segment from the nucleation and the depth of the rupture were never fixed. 2), the Tsetserleg event of 1905 July 9 at 9 hr 40 m UT [Mw = 8.4 (Kanamori 1977), Ms = 7.9 (Okal 1977)] and the Bolnay earthquake of 1905 July 23 at 2 hr 47 m UT [M = 8.7 (Richter 1958), Mw = 8.4 (Kanamori 1977); M = 8.2 (Khil'ko et al. Epicenter at 49.114, 89.707 A continuity of the waveform, during the gap related to the minutes mark, has been obtained using predictive filters. Hence, we first considered a nucleation at the southwestern end of the mapped surface ruptures, but the fit was poor. 139.2 km from 47.2 km from Then, the two predicted values are averaged with weights given by the corresponding standard deviations. It was discovered only in 1958 by V. A. Aprodov & O. Namnandorg (Aprodov 1960) and studied in detail by Khil'ko et al. 77.2 km from Kungurtug (6.2 miles). Since 1900, Mongolia has had 3 quakes of magnitude 8.0 or above, 9 quakes between 7.0 and 8.0, 35 quakes between 6.0 and 7.0, and 247 quakes between 5.0 and 6.0. (1993). An extension of the ruptures to the SW would imply that part of the Bolnay main fault broke, in contradiction with the previous wave modelling. This article about an earthquake in Asia is a stub. This appears to be the minimum depth of the rupture on Bolnay fault. The return periods on the Gobi-Altay segment are between 3000 and 4000 yr (Prentice et al. The tests with a change in the strike or a lower dip angle on the main rupture could not explain the amplitudes on Sh, Sv and P and became also inconsistent with the field observation. The 1905 M8 Tsetserleg-Bulnay earthquake sequence, which occurred 14 days apart in Mongolia, constitutes one of the major continental strike-slip earthquake sequence ever documented. Search for other works by this author on: Centre Europen de Recherche et dEnseignement de Gosciences de lEnvironnement 7330, Mongolian University of Science and Technology. A value near 60 km gives the best results, and explains better the end of the recorded signal (Figs 9a and b). It appears then necessary to introduce another rupture mechanism at the beginning of the earthquake. (137.2 miles), 2021-01-11 21:32:58 UTC Therefore, we allowed a freedom on the parameter rupture depth from 20 to 100 km. Theorie der automatischen Seismographen. Two great Mongolian earthquakes, Tsetserleg and Bolnay, occurred on 1905 July 9 and 23. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. Altay Van der Woerd J.

If we fix the depth to moderate value, the waveforms are explained (Table 3a). M. Rizza, J.F. 102.2 km from 8.3 magnitude earthquake. Michelot, M. Todbileg, ASTER Team; Earthquake Geology of the Bulnay Fault (Mongolia). 12). Thus, the region of the 1905 events consists of a transition zone with a rotation of 1 from N3049 to NS. It also propagated 80 km to the southeast along the Teregtiin fault. One occurred in 1931, one in 1957, and one in 1967, each one of magnitude 8 or greater, a rare record in the history of earthquakes anywhere in the world.

(b) Effect of the nucleation and rupture depths on the modelled body waveforms at Uppsala (Bolnay earthquake). Tocheport A. Although the surface ruptures associated with these two events are well-preserved due to dry climate, they had only been mapped in details along short sections. Zaysan Mongolia has had: (M1.5 or greater) 0 earthquakes in the past 24 hours 0 earthquakes in the past 7 days 0 earthquakes in the past 30 days 20 earthquakes in the past 365 days The largest earthquake in Mongolia: this year: 5.6 in Mugur-Aksy , Tyva , Russia Sorted: Biggest Nearby Places 102 years ago 8.3 magnitude, 15 km depth The Bolnay earthquake, 14 days later, starts at the intersection between the main fault (left lateral strike-slip) and the Teregtiin fault (right lateral strike-slip). Maintaining our website and our free apps does require, however, considerable time and resources. The maximum uncertainty induces a time error of 0.5 s at an amplitude of 30 mm. This time drift can be linear, sinusoidal or complex. The southern 50 km are complex (Voznesenskii & Dorogostaiskii 1914), with subvertical left lateral strike-slip faults oriented N80 (Khil'ko et al. Epicenter at 39.496, 96.616 The case, in which both durations were equal, was rare. The variation in amplitude, due to the observed b shift (maximum 33 mm), is less than 1 per cent for an arm length of 450 mm. The earthquake has been estimated at 8.25 [3] to 8.4 [2] on the moment magnitude scale . Spakman W. Comparison between the Gttingen and Jena S waveforms (Bolnay earthquake).

The Tsetserleg rupture (azimuth N60) correspond to a N60 oriented branch of the long EW oriented Bolnay fault. These events where studied by using Love G1 waves recorded at Gttingen (Okal 1977). Thus we needed a longer source history. The natural period, partially adjustable, varies between 9 and 15 s. The damping, by forced air circulation between a cylinder and a piston, is about = 4 1. At the first step, we model a nucleation at 17 km depth, near the base of the seismogenic zone, and a rupture propagating down to 30 km, the schizosphere zone (Table 3a). 2002; Zorin et al. Epicenter at 49.369, 96.61 Dverchre J. Introduction During the summer of 1905, two major earthquakes occurred along the Bolnai fault (also known as the Khangai fault in the U.S.S.R), in northern Mongolia, at 14 days' interval: event 1, on 'uly 9, 1905 *, was followed on July 23 * by event 11, a seemingly larger earthquake. Recorded seismicity in the BolnayTsetserleg region. (1985). Only magnitude 6.0 or greater earthquakes appear on the list. Der Kniglichen Gesellschaft der Wissenschaften zu Gttingen. Report it! Kendrick K.J. The nucleation and rupture depths remain uncertain. We fixed the depth of the nucleation at 15 km, but allowed for a deep propagation of the rupture (Tables 4a and b). Materials from the department of Physical Geographical Society of the USSR, Map of the earthquakes of 9 and 23 July, 1905 (scale1/420 000) SPb, New empirical relationships among magnitude, rupture length, rupture width, rupture area, and surface displacement. The added northeast segment should be associated with 7 m of left lateral strike-slip. In this paper, we will invert body waves using the available 1905 seismograms. Januar bis 31. Finally, we increased the fault length to the NE. They are orientated N 80 5 and they displace a river in a left lateral way (Table 4a). However, the seismic moment of Kokoxili is about 1021 N m (with 400 km active fault and slip of about 6 m) when the main segment of Bolnay is at minimum 3.3 1021 N m (with 375 km active fault and slip of about 10 m). T1 - The July 9 and 23, 1905, Mongolian earthquakes. The nucleation of the Tsetserleg earthquake is, for our favoured but not unique solution, at the western extremity of the central segment oriented N60 and characterized by left lateral strike-slip with reverse component. Show quakes near me! at 02:46 July 23, 1905 UTC, Location: Background. On the other hand, there were no Wiechert vertical components before 1906. Houdry-Lmont F.

Then, for signal duration of 150 s, the use of a unique emergence angle is acceptable for the 1905 July 9 and 23 events except for the end of the P wave which could be affected by PcP with another emergence angle. Lemiszki & Brown (1988), Blundel (1990), Klemperer & Peddy (1992), Jones et al. Raisbeck G.M. The cylinder and the paper are laterally displaced at a rate of 4.5 mm hr1 thus producing a helicoidally trace. Baykalsk The local velocity model used was one simple half-space crustal model with Vp = 6 km s1Vs = 3.46 km s1 density = 2.75 g cm3. at 03:37 December 04, 1957 UTC, Location: All selected instruments were Wiechert seismographs with a mass of 1000 kg (Wiechert 1903, 1904). Three cases have been explored: (1) nucleation and rupture in the seismogenic layer; (2) nucleation in the seismogenic layer with rupture propagation down to the base of the crust and (3) nucleation at the interface between the crust and the upper mantle with rupture propagation under the crust. The Teregtiin segment must break first since numerous tests, placing it later in the history of the source, do not explain the beginning of SH and P waves. For 1 horizontal and oriented NS, the best shape factor R is 0 (2 = 3), meaning uniaxial compression (Armijo & Cisternas 1978). Does the Great Glen fault really disrupt Moho and upper mantle structure? They were mapped a few months after the events (Voznesenskii & Dorogostaiskii 1914). All observed data has been normalized, using geometric and physical attenuation, to an epicentral distance of 40, and then the instrumental amplification has been changed to 10 000. 23.2 km from Epicenter at 51.639, 101.134 It has been associated to the 1905 July 23 earthquake because the scarp was fresh, and no other large event has been observed since. We inverted jointly these two parameters. Flannery B.P.. Ritz J.F. Kurtz R.D. The total rupture length for the Tsetserleg earthquake may reach up to 190 km, in order to explain the width of the recorded body waves. The Punjab Gov- earthquakes to the west and east of the Kangra rupture ), the most constrained parameters are the azimuth of the segments, the relative position of the segments and the slip angle. This last case appears to be the most satisfactory to explain our data. We compared the final signal of the different stations, and we observed a good correlation of the results even though the data were corrected separately. 153.2 km from This article about an earthquake in Asia is a stub. We could use only four stations (Jena, Gttingen, Uppsala and Strasbourg) because we selected the distance (30 to 90), the recording geometry (no circular recording as Ewing), damped seismometers (we did not use the Milne seismogram) and the largest possible azimuth distribution. You can help Wikipedia by expanding it. It is interesting to compare Bolnay earthquake with the Kokoxili earthquake (Kunlun, 2001 November 14, left lateral strike-slip, Mw = 7.9) whose nucleation and rupture depth are shallower than 20 km (Rivera et al. (1993)(Mo = 2.28 0.56 1021 N m), which is deduced from the surface ruptures and a hypothetical rupture depth of 20 km, is much smaller than our solution (Mo = 3.97 0.47 1021 N m). In consequence, it is possible for very large earthquakes to break under the seismogenic zone. 5). [2] However, this interpretation is contested; field surveys after the earthquake show a complex rupture not necessarily characteristic of a strike-slip mechanism.[5]. Then, we moved the nucleation to the southwestern end of the main fault with bilateral propagation (Fig. (50.2 miles), 1958-04-07 19:13:29 UTC For our study, we consider it as negligible. The same pendulum records the two horizontal components of the ground shaking, and may produce a coupling between them. 1987; Chen 1988; Dverchre et al. In the case of the Bolnay earthquake, the source duration is 150 s if we suppose a rupture velocity of 2.5 km s1 and a unilateral rupture along the 375 km of the main fault. Actually, we can compare Jena, Gttingen, Strasbourg and Uppsala since their epicentre-station azimuth varies less than 9 (Fig. Shihezi 10a). Thus, the needle movement corresponds to the intersection between a cylinder and a sphere. 2002; Ritz et al. Next, keeping the source nucleation at 17 km, we tested the propagation of the rupture in depth between 30 and 80 km (Table 3b). 3). Bulgan Institut de Physique du Globe, 5 rue Ren Descartes, 67084 Strasbourg, France. 47.2 km from King G.. Michelini A. The 1905 Tsetserleg earthquake occurred in or near the Tsetserleg Sum of Khvsgl Province in Mongolia on 9 July 1905. 2). Indeed, Kosmos satellite images show 80 km of active faults at the NE of the mapped surface ruptures. The 375-km-long surface rupture of the left-lateral, strike-slip, N095E trending Bulnay Fault associated with this earthquake is remarkable for its strong . In 1905 there were about a hundred seismic stations operating around the world (Wood 1921). Calais E. We thank two anonymous reviewers for their careful reading of the manuscript, and their valuable suggestions. De Simoni B. Altay For the Bolnay earthquake, we obtained S wave forms at Gttingen, Jena and Uppsala. Nevertheless, the natural period of the instruments, about 1015 s, smoothes the signal and could favour the inversion of such large values of depth. (79.2 miles), 2011-12-27 15:21:56 UTC Petit C. On the other hand, the Tsetserleg ruptures change in direction near the Tesiin River, where there are structures with EW extension and NS compression, suggesting a 1 oriented NS. Saryg-Sep We see that, 100 yr after these large events, the activity is still located near these faults. See quake list Quakes since 1900: Yiou F. San'kov V.. Jones A.G. Epicenter at 47.869, 85.076 If we consider 1 oriented N30, the best result is obtained for R = 0.5, corresponding to triaxial compression with 3 vertical. (2003). Along the 80 km stretch, between 97.18E and 98.33E, the fault zone is characterized by several meters width and the mean left-lateral 1905 offset is 8.9 0.6 m with two measured cumulative offsets that are twice the 1905 slip. Tapponnier P. The Jena station was not inverted, but compared to the synthetic (weight of 0 in the inversion), as the beginning of the predicted signal was poorly constrained, and since the station was near Gttingen. 1920-12-16 12:05:55 UTC As the first results were very unstable, we decided to filter the high frequencies at 10 s by a two poles Butterworth low pass filter. The 375-km-long surface rupture of the left-lateral, strike-slip, N095E trending Bulnay Fault associated with this earthquake is remarkable for its pronounced expression across the landscape and for the size of features produced by previous earthquakes. 10.2 km from The best total seismic moment, Mo = 7.27 0.40 1021 N m, is comparable to that estimated by Okal (1977)(Mo = 5.5 2.5 1021 N m). This representation is not valid at the beginning of the signal. How could so many catastrophic earthquakes occur within a single century and within two hundred miles of one another? This adds an inclination to the previous deformations of the signal (Fig. Station parameters for Tsetserleg and Bolnay earthquakes, 1905 July 9 and 23. doi: https://doi.org/10.1785/0120140119.

Gough D.I. Y1 - 1977/3. [2], There are few records of the immediate effects of the earthquake due to the remoteness of Mongolia in 1905. Epicenter at 50.038, 87.813 These large values could be related to the straight geometry of the rupture, limiting the barriers and allowing then a propagation of the rupture over an important length. The southern part of the Teregtiin fault, oriented N160, is a right lateral strike-slip segmented into several en echelon ruptures along 60 km (Fig. We could explain the strong amplitude on the SV and the rather small ones on the SH and P components.
