The August 17, 1914 Bilimbaev earthquake: location based on instrumental data

The parameters of the hypocenter of the Bilimbaev earthquake that occurred on August 17, 1914, are located. We performed earthquake location based on our compilation of all available seismological bulletins of the time that included data from the ISC-GEM (International Seismological Centre–Global Earthquake Model) project, the EuroSeismos project, and the Geophysical Survey of the Russian Academy of Sciences. The location was performed using a modified generalized beamforming method based on the ak135 travel time model and regional model by the Ural region. The new epicenter is removed from the epicenters, previous-ly determined from macroseismic and partly instrumental data, at a distance not exceeding 28 km. The previously calculated earthquake epicenters are in the region of the error ellipse of the new epicenter. The depth values indicated earlier also lie in the range of possible depths of the focus of the specified hypocenter. Thus, all the epicenters, including the new one, are relevant and with equal probability can be considered as the true epicenter of the earthquake

The Impact

Researchers at the Seismological Laboratory of the Institute of Geodynamics and Geology of the Federal Center for Integrated Arctic Research of the Russian Academy of Sciences (FCIARctic) have been engaged in the seismological monitoring of the European Arctic sector since 2011. In this paper, we present a comparative assessment of the earthquakes spatial distribution in this region based on the data from the International Seismological Centre (ISC) and the FCIARctic’s Arkhangelsk Seismic Network (ASN) obtained in 2012–2016. The paper presents the waveforms of earthquakes occurred at the Gakkel Ridge and the Svalbard archipelago processed with the use of a Russian software package WSG (Windows Seismic Grafer) recommended by the Unified Geophysical Service of the Russian Academy of Sciences. A standard 4–8 Hz bandpass filter was used for the processing of regional Arctic earthquakes. The impact of seasonal variations on the quality of earthquakes registration was analysed based on the seismograms recorded by the ASN’s island-based Arctic stations from 2012 to 2014 The same analysis was done for the central broadband sensor SPA0 of the Norwegian NORSAR-owned SPITS group installed at the Svalbard archipelago. A correlation has been established between the number of earthquakes recorded by the ASN’s island Arctic stations and SPA0 station. The number of regional earthquakes, recorded by ASN’s island Arctic stations is is smaller in summer-autumn periods than in winter periods. Forthe SPA0 station, which is part of SPITS group, there is not seasonality in the number of registered earthquakes. Generally, earthquakes are recorded uniformly, exception on January. This might be due to the increased seismic activity in the Svalbard archipelago during that period.

Study Base

The article provides information about G. Nechaev’s study, “Latinization of the Komi-Permyaks of the Ural Region”, dated March 7, 1933, deposited in the archival fund of the All-Union Central Committee of the new (Latinized) alphabet under the Council of Nationalities of the Central Executive Committee of the USSR, stored in the Archive of the Russian Academy of Sciences. The study noted that Permian Komi, who had been in high school and learned how to communicate in Russian somehow, no longer considered themselves Permian Komi, but considered themselves Russian. Information is given on three directions in resolving the issue of the Komi-Permyak alphabet: the great-power-chauvinistic one, which proposed the Russian alphabet; the one of Latinists who proposed the Latin alphabet, oriented to the Western bourgeois states; nationalistic one, oriented to V.A. Molodtsov’ alphabet based on modified cyrillic. Unification of the Komi-Permian alphabet, with all the shortcomings in work, made it possible to solve the main problem - the elimination of illiteracy, and the struggle of various directions showed the indigenous population's deep interest in creating and mastering the modern language. The information provided will expand the source study base on the history of linguistics, in particular the Komi-Permian language, and can be used for educational and research purposes.

The Relationship

This report describes an unusual and persistent dysphonia in two young women who had taken a therapeutic regimen of isotretinoin for intractable acne. We report perceptual and instrumental data for their dysphonia, and pose a theoretical basis for the relationship of dysphonia to this drug. We also provide recommendations for reducing the risk of acquiring a dysphonia during the course of treatment with isotretinoin.
