Dverchre J. Other branch is called the Dngen fault, located to the north of the Bolnay rupture, near its centre, and close to the junction of Bolnay and Tsetserleg. Comparison of the Bolnay S waveforms recorded at Jena, Uppsala and Gttingen after doing all corrections. San'kov V. b values chosen for the geometrical correction of the data. 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. Third, assuming a crustal thickness of about 50 5 km, we start with a nucleation near 45 km depth, and a rupture propagating down to 70 km (Table 3c). Melnikova V. It also propagated 80 km to the southeast along the Teregtiin fault. Additionally, each one of these events gave rise to fault movements as big as twenty feet and rupture lengths of several hundred miles. After scanning the records at high resolution, the original trace was precisely redrawn by using Adobe Illustrator.

Rizza, J.F. We could not decrease the rupture velocity because the P- and SH-wave signals would be too long. This representation is not valid at the beginning of the signal. (2003). Therefore, we will test various nucleation depths between 17 and 55 km. Amarjargal S. We thank two anonymous reviewers for their careful reading of the manuscript, and their valuable suggestions. 2005). 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. Surface ruptures, epicentre (star), focal mechanism of each segment, and rupture propagation direction (open arrows) for Tsetserleg (green) and Bolnay (red) earthquakes.

(151.2 miles), 2008-08-27 01:35:32 UTC Epicenter at 36.888, 105.606 However, rockslides were reported in the nearby mountains, and supposedly "two lakes, each of eight acres in size, disappeared". 4). In consequence, it is possible for very large earthquakes to break under the seismogenic zone. 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. (90.2 miles), 1967-01-05 00:14:41 UTC 133.2 km from Thus, the needle movement corresponds to the intersection between a cylinder and a sphere. 8.3 magnitude earthquake. All selected instruments were Wiechert seismographs with a mass of 1000 kg (Wiechert 1903, 1904). This Mongolia-related article is a stub. 1992) in the increasing and decreasing time directions, using the signal before and after, respectively.

The 11 January 2021 Mw 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. 1991, 2001; Bayasgalan 1999). The value of the arm shift is not measured during the recording, and it must be deduced. 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). The sign (-) is used when the writing arm is displaced to the north or the east. The case, in which both durations were equal, was rare. Particular effort has been done to retrieve a no deformed signal from the historical seismograms. 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. Epicenter at 37.645, 102.489 Bulletin of the Seismological Society of America (2015) 105 (1): 7293. Deep-seated structure and geodynamics of Mongolia . Indeed, this criterion produces artificial symmetry and is even more doubtful for surface waves, because it perturbs the dispersion. On July 9, 1905, an earthquake of magnitude 8.4 occurred in the GobiAltai region of southwestern Mongolia, close to the Chinese border. Only magnitude 6.0 or greater earthquakes appear on the list. The recent evolution of methods and tools allow us to extract more information from the 1905 seismograms: Is the Tsetserleg segment associated to the July 9 event?

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. A continuity of the waveform, during the gap related to the minutes mark, has been obtained using predictive filters. Beside the various parameters (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. The return periods on the Gobi-Altay segment are between 3000 and 4000 yr (Prentice et al. The rupture was bilateral along the main fault: 100 km to the west and 275 km to east. Altay Main active faults in Mongolia and the large earthquakes of the XX century (after Schlupp 1996). at 16:35 December 17, 1938 UTC, Location: McNeice G.W. Kosarev G.L. A left lateral movement characterizes its northeastern part with a reverse component dipping to the northwest. Kungurtug Khovd The seismic moment suggested by Baljinnyam et al. 2001; Petit et al. 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. When the first gap is preceded by only few seconds of signal, the quality of the prediction is limited. Epicenter at 45.971, 90.429 2003). The first part of the paper concerns the instrumental corrections. 1993). 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 What are the focal depth, rupture length and width, or seismic moment? We fixed the depth of the nucleation at 15 km, but allowed for a deep propagation of the rupture (Tables 4a and b). Levshin A.L. at 19:29 August 25, 1922 UTC, Location: 176.2 km from (66.2 miles), 1957-12-04 03:37:53 UTC to constrain them. at 21:18 August 10, 1931 UTC, Location: The new interest in the GobiAltai Region enabled the geological societies of Russia, China, and Mongolia to work together in the investigation of the 1957 earthquake when it struck. An empirical relation has been proposed where the displacement u = L, with = 1.5 105 for plate boundaries and 6.5 105 for intraplate earthquakes (Scholz et al. The Bulnay earthquake of July 23, 1905 (M w 8.3-8.5), in north-central Mongolia, is one of the world's largest recorded intracontinental earthquakes and one of four great earthquakes that occurred in the region during the 20th century. It starts at the southwest of the central subsegment, showing a left lateral strike-slip with a reverse component. Arrows show poorly explained waveforms. The first segment, known as Tsetserleg, is oriented N60E and has been mapped over 130 km. Our field observations suggest that in many areas the width and geometry of the rupture zone is the result of repeated earthquakes; however, in those areas where it is possible to determine that the geomorphic features are the result of the 1905 surface rupture alone, the size of the features produced by this single earthquake are singular in comparison to most other historical strikeslip surface ruptures worldwide. Van der Woerd J. Theorie der automatischen Seismographen. 1993). It was one of the very few for which detailed data was available. 10.2 km from 2003). We checked this postulate on modern seismograms. Baykalsk Active faults in Hangay region are in black. 1). The average horizontal displacements are of 10 2 m over 200 km, 8 2 m over 100 km and 5 2 m over 75 km (Baljinnyam et al. Saryg-Sep 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.

However, rockslides were reported in the nearby mountains, and supposedly "two lakes, each of eight acres in size, disappeared". 145.2 km from Comparison between the Gttingen and Jena S waveforms (Bolnay earthquake). 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. This adds an inclination to the previous deformations of the signal (Fig. 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. 102.2 km from Epicenter at 46.817, 89.915 Does the Great Glen fault really disrupt Moho and upper mantle structure? Usually it is restrained to the seismogenic layer. The Bulnay earthquake of 23 July 1905 (M w 8.3-8.5), in northcentral Mongolia, is one of the world's largest recorded intracontinental earthquakes and one of four great earthquakes that occurred in the region during the twentieth century.The 375 km long surface rupture of the leftlateral, strikeslip, N095Etrending Bulnay fault associated with this earthquake is remarkable for . 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. 2005) The previous magnitude published for the Tsetserleg event where: Okal 1977: Ms = 7.9 0.2; Kanamori 1977: Ms = 8.25; Abe 1981: Ms = 8.4; Baljinnyam et al. at 00:14 January 05, 1967 UTC, Location: Tosontsengel at 22:32 May 22, 1927 UTC, Location: (2002) used fault plane solutions from the TsetserlegBolnay sequence (Schlupp 1996) and two different procedures. The horizontal component works as a reversed pendulum with a stationary mass of approximately 1000 kg. Subsequent research, mainly in modern times after World War II, identified a series of earthquakes subsequent to the 1905 quake. 3). at 15:21 December 27, 2011 UTC, Location: Central Mongolia. 9.2 km from (23.2 miles), 1927-05-22 22:32:49 UTC (b) Effect of the nucleation and rupture depths on the modelled body waveforms at Uppsala (Bolnay earthquake). The fault displacement during the earthquake was greater than 6 m,[5] and possibly as much as 11 m,[2] and the duration is estimated at about two minutes. The amplification adjustment is mechanical, uses connecting rod and lever, and it is separated for each component. 47.2 km from The earthquake has been estimated at 8.25 [3] to 8.4 [2] on the moment magnitude scale . Epicenter at 45.189, 99.368 Such important variations in slip between segments are possible and have been recently observed after the Kokoxili earthquake (Klinger et al. (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 parameters of the solutions for the Bolnay earthquake (1905 July 23). Voznesenskii & Dorogostaiskii (1914), Voznesenskii (1962) and Khil'ko et al. To obtain good results using the linear predictive filter, the signal durations should be two to three times the natural period of the instrument. The solid friction reduces the amplification factor functions of the natural period of the instrument, the signal frequency and the recorded amplitude. Ritzwoller M.H. We cannot reject the possibility that the rupture propagates down through the whole crust (50 5 km), or even through a part of the lithosphere, which is about 100 km thick in this region (Villaseor et al. For our study, we consider it as negligible. 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. It appears then necessary to introduce another rupture mechanism at the beginning of the earthquake. (109.2 miles), 1932-12-25 02:04:30 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. 106.2 km from Ein astatisches Pendel hoher Empfindlichkeit zur mechanischen Registrierung von Erdbeben, A list of the seismological stations of the world, Low seismic velocity layers in the Earth's crust beneath Eastern, Siberia (Russia) and Central Mongolia: receiver function data, and their possible geological implication, 2007 The Author Journal compilation 2007 RAS, Geophysics-steered self-supervised learning for deconvolution, Local estimation of quasi-geostrophic flows in Earths core, Bayesian Detectability of Induced Polarisation in Airborne Electromagnetic Data, Analytical computation of total topographic torque at the Core-Mantle Boundary and its impact on tidally driven Length-of-Day variations, The ground deformation of the south-eastern flank of Mount Etna monitored by GNSS and SAR interferometry from 2016 to 2019, Volume 233, Issue 3, June 2023 (In Progress), Volume 233, Issue 2, May 2023 (In Progress), Volume 233, Issue 1, April 2023 (In Progress), Volume 234, Issue 1, July 2023 (In Progress), Geomagnetism, Rock Magnetism and Palaeomagnetism, Marine Geosciences and Applied Geophysics, Correction Of The Wiechert Seismograms Before Body Waveform Inversion, Body Waveform Inversion And Source History, https://doi.org/10.1111/j.1365-246X.2007.03323.x, Receive exclusive offers and updates from Oxford Academic, Copyright 2023 The Royal Astronomical Society.

(a) Effect of the nucleation and rupture depths on the modelled body waveforms at Jena and Gttingen (Bolnay earthquake). Along the 80km stretch, between 97.18E and 98.33E, the fault zone is characterized by several meters width and the mean leftlateral 1905 offset is 8.90.6m with two measured cumulative offsets that are twice the 1905 slip. 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. On one hand, we obtained the orientation of the main stress 1 at N30 using striations on the fault planes of the Bogd earthquake (Mw = 8.1 the 1957 December 4 associated to 250 km of surface rupture, with a main left lateral component, along the Gobi-Altay range; fig. How could so many catastrophic earthquakes occur within a single century and within two hundred miles of one another? In the case of P waves, we obtained the signal only at Uppsala. Der Kniglichen Gesellschaft der Wissenschaften zu Gttingen. The deformations due to the shift b are combined with those due to the whole geometry of the recording system. Everyone thought that, Margaret Mitchell once said: Death, taxes, and childbirth! 1920-12-16 12:05:55 UTC (43.2 miles), 1960-12-03 04:24:18 UTC (6.2 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. Lake Baykal, Russia. Russia . Two great Mongolian earthquakes, Tsetserleg and Bolnay, occurred on 1905 July 9 and 23. 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. Spakman W. (b) Source function of the Tsetserleg earthquake with an eastward rupture propagation. 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. Yiou F. 6. Saryg-Sep Epicenter at 48.168, 103.036 Theres never any convenient time for any. The source duration was 115 s. The moment magnitude Mw varies between 8.3 and 8.5.

We have 2.6 105 in the case of the Bolnay and Gobi-Altay earthquakes (Mongolia, 4 December 1957, Ritz et al. 2). 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. 5.6 earthquake - 13 km east of Mugur-Aksy, Republic of Tyva, Russia, on Friday, Jul 29, 2022 at 8:01 pm (GMT +7). Here, using sub-metric optical satellite images . If the result of the inversion gives, for one parameter, values inconsistent with field information, we fixed them to stabilize the solution. Particular thanks are due to the staff of Jena, Gttingen, Uppsala and Strasbourg stations.
