The Tsetserleg earthquake is believed to be a strike-slip rupture of a branch of the Bolnai Fault, extending about 190km. at 11:33 September 27, 2003 UTC, Location: Epicenter at 51.019, 98.15 Kendrick K.J. 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. Seismic reflection profiling and the structure of the continental lithosphere. The added northeast segment should be associated with 7 m of left lateral strike-slip.

To use it, it is necessary to know the radius of the cylinder, the length of the recording arm, and the distance from the axis of the rotating arm to the axis of the cylinder. This adds an inclination to the previous deformations of the signal (Fig. In consequence, it is possible for very large earthquakes to break under the seismogenic zone. A left lateral movement characterizes its northeastern part with a reverse component dipping to the northwest. Two of them are particularly interesting (Fig. In the case of western Mongolia the crust is thick (50 5 km; Villaseor et al. Kyren AU - Okal, Emile A. PY - 1977/3. Now at AixMarseille Unisit, CNRSIRDCollge de France, CEREGE UMR 34, BP80 13545 Aix en Provence, France; rizza@cerege.fr. The Teregtiin segment oriented N160, is characterized by a right lateral motion at the south west of the Bolnay fault. We fixed the depth of the nucleation at 15 km, but allowed for a deep propagation of the rupture (Tables 4a and b). Mugur-Aksy 220.2 km from The correction done independently for Jena and Gttingen shows a very good correlation (Fig. The Tsetserleg rupture (azimuth N60) correspond to a N60 oriented branch of the long EW oriented Bolnay fault. 2002; Zorin et al. In the case of the Tsetserleg earthquake, we obtained well-constrained S waveforms at Gttingen and Uppsala, despite a poorly predicted signal for the first gap at Uppsala. Surface ruptures associated with the Tsetserleg earthquake (1905 July 9, in green) and the Bolnay earthquake (1905 July 23, in red). Solutions for an eastward propagation during the Tsetserleg earthquake. Notice that in our case, the predominant period is about the natural period of the available instrument (1020 s). Actually, we can compare Jena, Gttingen, Strasbourg and Uppsala since their epicentre-station azimuth varies less than 9 (Fig. In general, each segment measures several tenths of kilometres, and in the case of Bolnay, they are very linear. After scanning the records at high resolution, the original trace was precisely redrawn by using Adobe Illustrator. (50.2 miles), 1958-04-07 19:13:29 UTC The total seismic moment is 1.06 0.05 1021 N m, giving Mw = 7.95 0.02. The best fit is obtained if it starts 17 s after the nucleation. On July 9, 1905, an earthquake of magnitude 8.4 occurred in the Gobi-Altai region of southwestern Mongolia, close to the Chinese border. Indeed, Kosmos satellite images show 80 km of active faults at the NE of the mapped surface ruptures. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. After a first earthquake that ruptured the Tsetserleg oblique fault strand, the second event ruptured the main Bulnay fault 14 days later. Two great Mongolian earthquakes, Tsetserleg and Bolnay, occurred on 1905 July 9 and 23. 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. Surface ruptures, epicentre (star), focal mechanism of each segment, and rupture propagation direction (open arrows) for Tsetserleg (green) and Bolnay (red) earthquakes. 2). In 1905 there were about a hundred seismic stations operating around the world (Wood 1921). "Source history of the 1905 great Mongolian earthquakes (Tsetserleg, Bolnay)", "Fault interaction and stress triggering of twentieth century earthquakes in Mongolia", https://en.wikipedia.org/w/index.php?title=1905_Tsetserleg_earthquake&oldid=1133365086, This page was last edited on 13 January 2023, at 12:01. 24.2 km from By doing this, we obtained good results on most parts of the signal (Fig. It starts at the southwest of the central subsegment, showing a left lateral strike-slip with a reverse component. However, rockslides were reported in the nearby mountains, and supposedly "two lakes, each of eight acres in size, disappeared". Its value generally varies from 150 to 250 for the 1000 kg Wiechert. (1993). Artemyev A.A. Nevertheless, the natural period of the instruments, about 1015 s, smoothes the signal and could favour the inversion of such large values of depth. The cylinder and the paper are laterally displaced at a rate of 4.5 mm hr1 thus producing a helicoidally trace. Here, using sub-metric optical satellite images . For the P waves, we obtained good signals at Jena and Uppsala. at 01:03 October 01, 2003 UTC, Location: 6 Celebs Who Lost Their Lives Under the Knife. Amarjargal S. 140.2 km from Thus, the needle movement corresponds to the intersection between a cylinder and a sphere. Heres The Truth! Does the Great Glen fault really disrupt Moho and upper mantle structure? Ritz, C. Prentice, R. Vassallo, R. Braucher, C. Larroque, A. Arzhannikova, S. Arzhannikov, S. Mahan, M. Massault, J.L. Amato A. at 09:09 December 27, 1991 UTC, Location: Xu X. 1905-07-09 09:40:39 UTC at 09:40 July 09, 1905 UTC Location: Epicenter at 49.709, 98.483 . (2003) estimated a left lateral slip rate of 2.6 1 mm yr1 on the Bolnay fault, using GPS measurements (from 1994 to 2002), giving a return period of 4500 1750 yr. The PcP arrives at more than 1 min for Gttingen and Jena and at more than 1.5 min for Uppsala after the P. 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. Station parameters for Tsetserleg and Bolnay earthquakes, 1905 July 9 and 23. 244.2 km from (28.2 miles), Location: 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. But the average slip (6 2 m) during the Kokoxili event is smaller than that of the Bolnay earthquake (8 2 m to 10 2 m). 2005). In parallel, paleoseismological investigations show evidence for two earthquakes prior to the 1905 event with recurrence intervals of ~2700-4000 years. at 15:21 December 27, 2011 UTC, Location: N2 - 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. This allows us to verify the quality of the different corrections and rotations previously done on the data, as shown in Fig. 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. 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. This representation is not valid at the beginning of the signal. We determined the source history of these events using body waveform inversion. 176.2 km from A .gov website belongs to an official government organization in the United States. The depth of the rupture was always free. 86.2 km from These events where studied by using Love G1 waves recorded at Gttingen (Okal 1977). This work has been possible thanks to the archives of the world wide seismic stations. Your email address will not be published. Finally, the last solution, with the nucleation at 43 km depth and a rupture propagating down to 70 km, appears to be the most satisfactory. We also tested rupture propagation to the west with the same segments. San'kov V.. Dverchre J. Morphotectonic analyses carried out at three sites along the eastern part of the Bulnay fault, allow us to estimate a mean horizontal slip rate of 3.1 1.7 mm/yr over the Late Pleistocene-Holocene period. The total duration of the modelled source function is 65 s. The seismic moment deduced from the inversion is 1021 N m, giving a magnitude Mw = 8. Theorie der automatischen Seismographen. The parameters used in the source model are: azimuth, dip, slip on the fault, scalar seismic moment, depth of the nucleation, depth of the centrod of each segment, amplitudes of the source time function and relative position of the different segments. Kosarev G.L. Antoine Schlupp, Armando Cisternas, Source history of the 1905 great Mongolian earthquakes (Tsetserleg, Bolnay), Geophysical Journal International, Volume 169, Issue 3, June 2007, Pages 11151131, https://doi.org/10.1111/j.1365-246X.2007.03323.x. This time drift can be linear, sinusoidal or complex. Active faults in Hangay region are in black. Lemiszki & Brown (1988), Blundel (1990), Klemperer & Peddy (1992), Jones et al. In practice, the equilibrium position of the needle arm may not be perpendicular to the driving cylinder axis. 47.2 km from at 18:21 December 22, 1906 UTC, Location: 1985; Ritz et al. Comparison between the Gttingen and Jena S waveforms (Bolnay earthquake). The Dngen complex segment, a NS right lateral strike-slip of about 1.5 0.5 m, is at the junction between the ruptures of the July 9 and 23 earthquakes (Baljinnyam et al. (1993). 1993). As the vertical recording system did not exist that time, we used the values of emergence angles from the IASPEI91 model (Kennett 1991) in order to estimate the amplitudes of the SV and P. Within the working windows (140 to 150 s), we recorded the following waves: S/pS/sS/SPn/PnS which have a similar emergence angle (differences less than 0.5 degrees). Altay In particular they saw that what had happened in the GobiAltai earthquake, namely the simultaneous rupturing of two major faults, were to happen in California, it would be worse than anything that had yet hit that state. We could explain the strong amplitude on the SV and the rather small ones on the SH and P components. T1 - The July 9 and 23, 1905, Mongolian earthquakes. 1993). Bulletin of the Seismological Society of America (2015) 105 (1): 7293. E. in der Zeit von 1. Aktash Everyone thought that, Margaret Mitchell once said: Death, taxes, and childbirth! We deduced different b values for each record with an uncertainty going from 1 to 3 mm (Table 2). With the data from 1905 available to them in 1957, and encouraged by the new interest in eastern Siberia by political leaders, geologists began to study the GobiAltai region in greater detail than had ever been previously attempted. The t* values considered are 1 s for P waves and 4 s for S waves. The P projection on the NSEW plane and the emergence angle, allowed us to deduce the P waveform. Epicenter at 51.839, 95.921 2003) in the area of the Tsetserleg and Bolnay earthquakes. This article related to the history of China is a stub.

Brown E.T. Saryg-Sep at 09:40 July 09, 1905 UTC, Location: In 1905, two M ~ 8 continental strike-slip earthquakes occurred along the Bulnay fault system, in the northwestern part of Mongolia. What is their source history? 3). Latest earthquakes in Mongolia: list & interactive map Updated: Feb 7, 2023 15:20 GMT - 19 minutes ago refresh Felt a quake? 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 . Therefore, even though the timing mechanism is common for the two components, the beginning of their minute marks may be different. 1). The Uppsala, Gttingen and Jena stations were on granite, on limestone and on sandstone, respectively. 33.2 km from (151.2 miles), 2008-08-27 01:35:32 UTC 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. 2003). Background. (15.2 miles), 1931-08-18 14:21:05 UTC (b) Source function of the Tsetserleg earthquake with an eastward rupture propagation. Calais et al. The parameters of the solutions for the Tsetserleg earthquake (1905 July 9). The 1905 Bolnai earthquake occurred in or near the Asgat Sum of Zavkhan Province in Mongolia on 23 July. Geologists have concluded that, in this poorly understood region, events like these appeared in cycles over geological time with recurrence rates of several thousands of years. Baiyin A large number of rocks rolled down from the 12,000 feet high surrounding mountains, trees were uprooted, and two lakes, each of eight acres in size, disappeared. Solonenko N.V. The trace is then transformed to a dense set of points, with coordinates (xi, yi). Barmin M.P. This implies a difference of less than 5 s between the length of P- and S-wave signals, too short to be observed with certainty. Seismogram (vertical component) last 60 minutes. 45.2 km from 2001; Petit et al. Belichenko B.G. This catastrophic event in 1905 was an exception. The minute gaps at Gttingen are corrected by using predictive filters. (66.2 miles), 1957-12-04 03:37:53 UTC Franceschi D.. Prentice C.S. Recorded seismicity in the BolnayTsetserleg region. Altai 69.2 km from Delouis et al. 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. The return periods on the Gobi-Altay segment are between 3000 and 4000 yr (Prentice et al. Considering the amplitudes being analysed, these uncertainties are negligible. San'kov V.. Jones A.G. Bayanhongor (2002) used fault plane solutions from the TsetserlegBolnay sequence (Schlupp 1996) and two different procedures. The EW oriented Bolnay rupture is characterized by an almost pure left lateral strike-slip over a length of 375 km (all ruptured segments give a length of 455 km). We thank our colleagues from the Mongolian Academy of Sciences (Ulaanbaatar), the Mongolian University of Science and Technology (Ulaanbaatar), the Institute of Physics of the Earth, (Moscow) and the Institute of Earth's Crust (Irkutsk) for the facilities we had during the field work. The magnitude Mw is between 8.34 0.04 and 8.51 0.02. 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. It also propagated 80 km to the southeast along the Teregtiin fault. We verified the stability of the linear prediction by changing the length of the signal used in the filter. The southern 50 km are complex (Voznesenskii & Dorogostaiskii 1914), with subvertical left lateral strike-slip faults oriented N80 (Khil'ko et al. You can help Wikipedia by expanding it. This strategy is important as the result of the inversion depend strongly on the initial value of the parameters. We could not decrease the rupture velocity because the P- and SH-wave signals would be too long. (20.2 miles), 2003-09-27 11:33:25 UTC (1985) reported a right lateral component on a subvertical NS oriented fault. Since 1900, Mongolia had 294 quakes up to magnitude 8.3. Altay Additionally, each one of these events gave rise to fault movements as big as twenty feet and rupture lengths of several hundred miles. 106.2 km from 153.2 km from Show quakes near me! It was one of the very few for which detailed data was available. However, rockslides were reported in the nearby mountains, and supposedly "two lakes, each of eight acres in size, disappeared". The time waveform is modelled by a set of triangular source elements (Nabelek 1984). The value of the arm shift is not measured during the recording, and it must be deduced. The fault displacement during the earthquake was greater than 5 m,[3] and the duration is estimated at about one minute. The first segment, known as Tsetserleg, is oriented N60E and has been mapped over 130 km. On July 9, 1905, an earthquake of magnitude 8.4 occurred in the GobiAltai region of southwestern Mongolia, close to the Chinese border. 64.2 km from Their observations were completed by Aprodov (1960), Khil'ko et al. All selected instruments were Wiechert seismographs with a mass of 1000 kg (Wiechert 1903, 1904). Particular effort has been done to retrieve a no deformed signal from the historical seismograms. 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. 2). a: Model with an eastward rupture propagation: Mo total = 1.06 0.05 1021 N m = >;Mw = 7.95 0.02. The 11 January 2021 M w 6.7 Hovsgol, Mongolia, earthquake is the largest event that has occurred in the Hovsgol graben, which is noted for being the northernmost convergence region of the India-Eurasia collision and the youngest extension region of the Baikal rift. THE Kangra earthquake of 4 April 1905 in the north-west been ruptured by these great earthquakes. 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. Hence, we first considered a nucleation at the southwestern end of the mapped surface ruptures, but the fit was poor. The stress 1 varies from N30, at the south, with a form factor R = 0.5 (triaxial compression with 1 vertical), to NS, at the north, with a form factor R = 0 (uniaxial compression). All of the information we now have about the 1905 event came from one Russian seismologist who traveled to the area of the earthquake at his own expense, in 1905, and by primitive means of transportation. TY - JOUR. 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. Engdahl E.R. Nevertheless, the important mass of the Wiechert (1000 kg) limits its impact. lgiy . Aktash Nevertheless, we cannot explain the amplitude or the SH polarity (Fig. Latest earthquakes in Mongolia: list & interactive map Updated: Feb 4, 2023 14:56 GMT - 1 day 6 hours ago refresh Felt a quake? 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. 38.2 km from The displacements are of the order of 3 1 m (Baljinnyam et al. 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. Thus we favour the eastward propagation as proposed by Okal (1977). It would be at least 40 km for Bolnay. The obtained displacement on the central segment was 6.3 m, much higher than the 2 m observed on the field (Baljinnyam et al. Background [ edit] Epicenter at 50.211, 87.721 A local stress tensor in the Tsetserleg area is proposed from surface ruptures. Therefore, we will test various nucleation depths between 17 and 55 km. A value near 60 km gives the best results, and explains better the end of the recorded signal (Figs 9a and b). The average displacement is 2 0.5 m for the horizontal component and about 1 m for the vertical component. 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. 3). 127.2 km from (23.2 miles), 2003-10-01 01:03:25 UTC 1a). The observed surface ruptures are about 130 km long. The earthquake has been estimated at 8.25 [3] to 8.4 [2] on the moment magnitude scale . How could so many catastrophic earthquakes occur within a single century and within two hundred miles of one another? Both shocks were reported felt over several millions . Voznesenskii and Dorogostaiskii reached the region only 3 months after the earthquake, but they had enough information to say that the first event is associated to the Tsetserleg earthquake, and the second one to Bolnay. The seismic moment released by the July 23 earthquake is four to seven times greater than that of the 1905 July 9 earthquake. Tapponnier P. The 1905 Tsetserleg earthquake occurred in or near the Tsetserleg Sum of Khvsgl Province in Mongolia on 9 July 1905. Calais E. at 02:49 February 13, 1933 UTC, Location: On the other hand, there were no Wiechert vertical components before 1906. Okal (1977) proposed a rupture propagating eastwards along a fault oriented EW. The total duration of the modelled source is 65 s for Tsetserleg and 115 s for Bolnay earthquakes. 13 shows the recorded seismicity from 1964 up to 2000 (Adiya et al. San'kov V. (79.2 miles), 2011-12-27 15:21:56 UTC Dverchre J.. Delouis B. Gough D.I. The surface ruptures show almost pure left lateral strike-slip with displacements between 8 2 and 11 2 m (Khil'ko et al. 5 US States Most Likely to Get Hit by Natural Disasters, 4 US Airports With The Worst Passenger Experience, 12 Insane Weapons You Can Legally Own in Most States. We made the hypothesis that there was no P/SV conversion under the station that could modify the P waveform on the horizontal component, and then perturb the calculation of the P wave. 1993:Mw = 7.5 0.1. 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. 133.2 km from A year later the Academy of Sciences of the USSR, the name of the country at that time, appointed a group of geologists to investigate the GobiAltai area, to map it in detail and to carry out seismological investigations over a large area. 2002). As 1Hz is a reasonable sampling for the digitization of low speed mechanical seismograph recordings and as we do not need higher frequencies, we sampled down the data to 1 second after applying a low pass filter (Butterworth with two poles) anti-aliasing at 2 s. The impact of the low pass filter is negligible for our study, as the record is made at teleseismic distances, and the natural period of our instruments is large, between 10 and 14 s. In order to fill the gaps at the minute marks, we applied a linear predictive filter (Press et al. Bayasgalan A. P-wave polarizationBolnay 1905 earthquake. The best results were obtained when we invert one to two parameters together, avoiding a rapid drift to aberrant solutions. The signal was recorded on smoked paper. Fig. 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. Then, the two predicted values are averaged with weights given by the corresponding standard deviations. 5). Schlupp A. b Main shear rupture of the Bolnai earthquake 1905, M w 8.4. 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). Epicenter at 36.888, 105.606 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. We tested three cases: (1) nucleation and rupture depth limited to the seismogenic zone; (2) nucleation in the seismogenic zone and rupture propagation going to the base of the crust and (3) nucleation within the crust-upper mantle interface and rupture propagation within the upper mantle. Therefore, we allowed a freedom on the parameter rupture depth from 20 to 100 km. 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). 2003). Saryg-Sep at 12:05 December 16, 1920 UTC, Location: (86.2 miles), 1905-07-09 09:40:39 UTC In conclusion, the nucleation must be near the junction of the Teregtiin and Bolnay faults, thus respecting a mainly eastward rupture propagation. Thus, the region of the 1905 events consists of a transition zone with a rotation of 1 from N3049 to NS. The problem being non-linear, we cannot quantify exactly the effect of friction. doi: https://doi.org/10.1785/0120140119. Van der Woerd J. at 18:52 September 27, 2003 UTC, Location: The Tsetserleg rupture (azimuth N60) correspond to a N60 oriented branch of the long EW oriented Bolnay fault. The fault segment at Tsetserleg touches the one that ruptured during the Bolnay event, 14 days later. (1992) and McBride (1995) observed from seismic profiles that strike-slip faults can cut the Moho. Russia . Your email address will not be published. Fairhead D.. Pintore S. Show quakes near me! The Dngen rupture broke about 24 s after the nucleation. 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. Adding this segment improves the SH and SV waveforms and gives higher amplitude on the P (Fig. The 1 direction makes an angle of 80 with the southern segment when 1 is oriented NS, and 60 when 1 is oriented N30. at 01:35 August 27, 2008 UTC, Location: The seismic moment suggested by Baljinnyam et al. (1993). We observe that: solid friction becomes very important for small amplitudes (less than 6 mm for Gttingen) even at periods (about 9 s) smaller than the natural period (about 14 s). Maintaining our website and our free apps does require, however, considerable time and resources. See quake list Quakes since 1900: Loncke L. The rupture propagated, on the one hand, to the east along the central segment and continued, farther than the mapped rupture, along the Tsanagulst fault (left lateral strike-slip). at 12:47 June 14, 1990 UTC, Location: 9.2 km from 23.2 km from The particle motion of the P wave is polarized along the direction of the path of the wave. Dverchre J. Januar bis 31. at 22:32 May 22, 1927 UTC, Location: You can help Wikipedia by expanding it. In the case of P waves, we obtained the signal only at Uppsala. This implies adding 60 km to the previously mapped fault. Its length is about 375 km (Fig. Additionally, Devastatingdisasters.com participates in various other affiliate programs, and we sometimes get a commission through purchases made through our links. at 14:21 August 18, 1931 UTC, Location: Demjanovich MG, Borisov BA, Vashchilov YY (1995) Deformation and faulting at large earthquakes in Mongolia-Siberian region.
