After the destructive Siduoka earthquake of July 11th, 1935. in strongly shaken area a precise levelling along a route of old Tokaido extending from Tegosi, Siduoka, to Sodesi near Okitu, and that along a route extending from Kunosan-sita to the eastern bank of the river Abe along Suruga Bay were carried out in four times. The relative vertical displacements of the bench marks along these level lines obtained by comparing the results of the recent measurements with those of earlier ones are shown in Table I-IV and in Fig5. 2~6. The writer made some discussions for the results.

From the period of perestroika, there has been an argument in the criticism of Soviet culture that the Stalinist culture suppressed the representation of the body, which is irreducible to the canonical language. In this body/language opposition, the body is seen as deviation, excess or something antagonistic to the social and language order. But it is not appropriate to think that the body can be represented outside of and autonomous from language because, taking this assumption and regarding the body as something that needs release from the yoke of the language order, we only repeat the same scheme of such sayings that the body must be suppressed by language. The body should, therefore, be seen as that formed in the practice of language. In this light, dissident writer Aleksandr Solzhenitsyn's text appears to tell how the body is formed in the language activity and treated by the language order. His text does not take the body/language opposition for granted, but probes the mechanism which this opposition stands on. Solzhenitsyn's novel, The First Circle, describes the process of the formation of the body far more clearly and elaborately than in any other of his writings. The central motif of the novel is voice-hearing, which inevitably raises the question of the relation of language and body. That is because, on one hand, voice carries linguistic messages, but on the other, it is a part of the human body. Voice separates from the body and goes through various media (recorder, telephone, radio etc.), but in this process it does not seem to lose the trace of the body in the form of its materiality, such as frequency and amplitude. This duality of voice plays a decisive role in The First Circle. In the beginning of the story, Innokentii Volodin, a young diplomat, calls the embassy of the United States in Moscow and reveals that a Soviet agent will receive information about the manufacturing of an atomic bomb. His conversation is tapped and recorded, and the Ministry of State Security (MGB) commits the tape to a special prison-institute commonly called a sharashka, where confined scientists and engineers are working for the benefit of the government. Gleb Nerzhin, a mathematician, and Lev Rubin, a linguist, are ordered to analyze the tape and identify the criminal among five suspects. The novel depicts in detail the process of voice analysis, which is to be examined concretely in this paper. Previous studies on Solzhenitsyn's novels have not read these technology motifs in their literal meaning. If attention is paid to descriptions of technology, they tend to concentrate on metaphorical and ideological interpretations of them (the telephone network stands for the bureaucratic system of the socialist state, for instance) and ignore the material and practical aspect of them. Solzhenitsyn himself lived in a sharashka for three years, and the model of Nerzhin is the author. He compared the sharashka to "the first circle" (borrowed from Dante's The Divine Comedy), which is the most privileged place among the concentration camps. There, prisoners were exempted from hard labor and even enjoyed freedom of speech, unthinkable in the outside society. Their work was directly connected with the benefit of the state, and significant contribution sometimes freed them. Many technical experts imprisoned in the sharashka, however, belonged to the generations before the Revolution, and a part of them were anti-Stalinist sympathizers. What sustained this inclination was their assurance of the autonomy of "techno-elite," but in fact their life depended on the technological innovation which they devised for the regime. In other words, the channels of their voices are strictly controlled, but at the same time their technology regulates the conditions on how voices are transmitted. Located in this ambiguous position of sharashka, the prisoners in The First Circle are confronted with difficult ethical questions to decide one after another. The depiction of the analysis of Volodin's voice is based on a true story Solzhenitsyn experienced in the sharashka and that Rubin's model Lev Kopelev wrote a detailed memoir about. By the time they take up Volodin's case, the prisoners have been engaged in the development of a scrambler phone that can protect Stalin's telephone conversation from being tapped by encoding and decoding human voices. The decoded voice must be identifiable with the speaker as well as being clearly heard. Looking back to the duality of voice mentioned above, clarity of voice (what one is saying) is related to its linguistic aspect, while identification (who is speaking) to its materiality or body. The latter is considered more complicated than the former, and what is necessary for the analysis of Volodin's voice is the latter (who is the criminal). To develop this special apparatus, Nerzhin (Solzhenitsyn) and Rubin (Kopelev) used a device called "visible speech," the prototype of today's sound spectrograph. It gives voiceprints which records frequency and energy of voices according to time. Rubin thinks their patterns differ from person to person, so he can identify the criminal by comparing the voiceprints of given tapes. But, in fact, voiceprint does not reveal the owner of the voice by itself. It only transcribes the materiality (body) of voice, which is unique and unrepeatable every time. To identify the owner, one must find some distinct features of his voice, always unchangeable. Rubin (Kopelev) has inmates and staff in the sharashka read the same words and syllables in various ways, but, as he confessed, Kopelev could not discover such features. What is important here is that the identity of voice is sought by articulating its materiality (voiceprints) linguistically (by particular words and syllables). In The First Circle, through voice analysis, Rubin focuses his attention on two suspects, Volodin and Shchevronok, and he tells his boss that Shchevronok is more suspicious. But that is a mistake. His boss reports to a MGB official about two suspects, requiring more data, but the official rejects the request and announces that he will arrest both. Here the strict examination of voice properties turns to absurdity. We might wonder, with all of the complicated investigation, which Rubin is forced to work on, why the author lets Rubin make a mistake and for the authorities to arrest an innocent man. Before answering this question, we should reexamine the special nature of Volodin's case -- a crime on the telephone line. As it was already seen, voice has two aspects; it is regarded as a trace of the body (and this trace also has materiality) and a carrier of language simultaneously. This duality of voice makes Volodin's case very unique. On one hand, his voice transmits linguistic message, which is recognized as a crime in the social order. On the other hand, his voice is the criminal act itself. It means that the language order and the bodily act are connected directly in his voice. Usually, bodily acts, occurring in particular time and space, are unrepeatable. But Volodin's recorded voice makes it repeatable. Through the process of voice analysis, the repeatable body (materiality) of voice is articulated to the language order and identified with its owner. In this sense, the identifiable body of the criminal is formed in the practice of the language order. We may think that Rubin's mistake shows the imperfection of this articulation system: he could not tell the difference between two men's voices. This imperfection, however, is necessary to the order. Stalin in the novel suspects that 5 to 8 percent of the people in the state are not content with the present regime although they vote for it in elections. Stalin asserts that the MGB can exist only because there are always hidden enemies in the society. His suspicion keeps on creating newly imagined enemies, who do not appear in elections, that is, who are not articulated to the language order (election has the simplest linguistic form -- yes or no). This supposed percentage of hidden enemies can be seen here as corresponding to the percentage Rubin mistakes. For Rubin's identification process is accompanied with the possibility of misidentification, and this misidentification (the imperfection of articulation) produces the hidden body of enemies behind the language order. Thus, the imperfection of the articulation technology makes the language order produce suppressible body. The voice analysis depicted in the novel shows the process of how the deviant body is produced, identified and oppressed in the regulation of social and linguistic order. Along with Rubin's voice analysis, the novel presents a different kind of voice-hearing. Nerzhin is said to have "strange hearing," with which he has been able to hear suppressed people moaning and shrieking since his childhood. This voice reaches him without going through any material medium -- newspaper, radio, or telephone. He does not trust them at all. Volodin's voice is carried by the telephone line and analyzed by the device of visible speech, by which, as a result, he is arrested. Adding to such media technologies, one more medium participates in voice analysis -- the body of the analyzer (Rubin); the clarity of decoded voice is examined by his ears, one of which is deaf, a fact which Rubin hides from people around him. Furthermore, when Rubin (Kopelev) has to infer from a voiceprint what the voice is saying in front of a MGB official, Nerzhin (Solzhenitsyn) secretly tries to help Rubin by showing the answer by gesture. All these mediums are described as things which deceive people. Among the mediums in the novel, written letters in documents are particularly deceptive. Recorded letters are easily placed under the control of a third party so they do not hold the truth. The cause of the deceptiveness is the materiality of media and body. Nerzhin's hearing is "strange" and fantastic because it omits such media technology and body, which seems indispensable for normal communication, and still can catch voices. Denying all the mediums, Nerzhin tries to approach the origin of suppressed people's voice. In the sharashka he likes to go and listen to Spiridon, a plain peasant, because Spiridon is a blind and illiterate man that is cut from the deceptive media networks (Rubin calls this Nerzhin's "going to the people" in fun). Nerzhin cannot learn any principle of life from Spiridon's tales, but just listens to his voice through his "soul" while sitting side by side; Nerzhin's hearing is independent of reason and media. Nerzhin goes further this way "to the people" and takes a much more radical step by refusing to take part in the work on the cryptography for the scrambler phone, as a result of which he is sent to a regular concentration camp. To leave the sharashka, which serves the regime with media technology, means that he will join the truly suppressed people. At the last moment in the sharashka, Nerzhin sees the van that will transport him and fellow prisoners elsewhere through Moscow city. He sees the word "Meat" painted on the body of the van for disguise. This detail has rich implication. The word "Meat" does not only hide the body of prisoners in the car, but exposes by accident the violence of the language order which treats the human body as "meat." In this scene, violence is not generated in the situation where language has already screened out the body as recent criticism insists, but when language designates the body in a certain way. Throwing his own body from the language order to outside of it, Nerzhin reveals such violence because in this moment he can observe both aspects of Soviet society. This is the point where the relation between language and body is determined. After that, the viewpoint of the narrative suddenly switches to a foreign newspaper reporter who sees the van on the street and takes the word "Meat" as it is. Nerzhin's body vanishes to outside of language but leaves the strange hearing to readers, who now know the violence of language. This consequence of Solzhenitsyn's novel has been criticized in two ways; first, it distinguishes the world of suppressed ordinary people as something sacred. Secondly, it stands in an omnipotent position which commands view of both sides of Soviet society. These arguments are apparently true, but, as we have seen in this paper, The First Circle narrates how two aspects of society (suppressing language order and suppressed body) are being separated. In this separation consists violence, which is depicted in the last scene of the novel (the scene about the "Meat" van). In fact, Nerzhin's vanishing body acts as the medium that informs readers of the two aspects of Soviet society, though he will not admit that the human body functions as a medium. It can be said that Solzhenitsyn himself, when he writes The Gulag Archipelago, for example, works as such a medium, articulating the "reality" of concentration camps to language text.

Les observations accelerometriques ont etc continuees encore pendant 1934 aux memes stations dans les deux villes. A cette annee nous avons reussi a enregistrer 15 seismes de degree II et 2 seismes de degree III. L'acceleration maxima corresponded a chaque seisme a etc determinee et montree dans le tableau II. D'une part elle est superieur a la partie haute de la ville quand la distance epicentrale reste moins que 50 km. D'autre part la periode predominante dans les secousses sismiques est comparativement petite ii la partie haute de la ville. Nous constatons que la periode predominante corresponde a celle d'oscillation propre de la couche superficielle du terrain et elle a un rapport serre avec des dommages sismiques. De plus, nous avons essaie de trouver quelque relation entre la periode des secousses provoquees artificiellement et la periode predominante dans les secousses sismiques, mais nous n'avons pu constater aucune coincidence entre eux.

Du 14 Fevrier 1930 an 22 Avril de la meme annee, an grand nombre de seismes ont eu lieu dans la region d'Ito, ville d'eaux situee au bord oriental de la presqu'ile d'Idu. Dans le but d'etudier le mouvement de la croute terrestre a l'occasion de ces seismes, on a installe un paire de pendules horizontaux (clinographes de silice fondu, inventees par le Prof. M.Ishimoto) a Ito afin d'observer les variations de l'inclinaison de la surface terrestre; les observations ont etc effectuees a, partir du 12 Mars. De plus, le 19 Mars une installation iclentique a ete faite a Kawana et les deux observations ont ete poursuivies jusqu'au 30 Juiri. La sensibilite du clinographe a Ito etait reglee de facon a donner 1 cm. de deviation pour 1 seconde d'inclinais-on, tandis que la sensibilite du clinographe a Kawana et les deux fois plus grande que celle du clinographe d'Ito. Les clinographes etaient installees dans des caves creusees dans la masse de scorie volcanique.

In this paper the crustal structure of the South Fossa Magna region, where a Tertiary geosyncline is developed, is inferred geologically under some assumptions. The method here adopted consists of two steps; 1) preparation of the stratigraphic profiles in every stage of geological devolopment of the region, and 2) modification of the stratigraphic profiles by the subsequent deformation of the crust. 1) Preparation of the stratigraphic profiles. The early Miocene Misaka and the middle to late Miocene Fujikawa series are the main conponents of the nearsurface crust of the region. They vary in thickness in different geological provinces in the region. Their geologic and tectonic maps are shown in Figs. 1 and 2. The pre-Misaka sediments are supposed geologically to have been deposited on the oceanic crust of transitional crust between the main Japanese Islands and the Pacific. These data and assumptions as well as those listed in A) of Table 2 are used for the stratigraphic profiles of the region (Fig. 3). 2) Modification of the stratigraphic profiles. After the deposition of the Misaka series, the following events took place: i) crustal warping with deposition of the Fujikawa series in the downwarping parts and with erosion of the Misaka series in the upwarping parts, ii) intrusions of quartz diorite stocks of the uplifted parts, and iii) formation of the crystalline schist along the southern limb of the Tanzawa upwarping part. (Boulders of the quartz diorite and of the crystalline schists appear in the upper part of the Fujikawa series of the subsiding belts). Until the end of the deposition of the Fujikawa series, the crustal surface was de- formed in a wavy contour as shown in curve s-s of Fig. 4. From the observations of the Tanzawa schist belt, we can assume that the wavy deformation of the crust mentioned above is due to shear fold with the shear plane inclined northward with angle about 70°. Then we get curve b-b in Fig. 4 as the bottom of the crust. Besides, it is assumed that the quartz diorite magma originated due to melting of the crust and the Mohodiscontinuity represents a boundary between two different materials (the basaltic and ultramafic), and that the volume change of the crust through the magmatic process which brought the quartz diorite stocks and through other tectonic process is negligible. Thus, we get Fig. 5 (b) as the crustal structure of the South Fossa Magna at the end of the Fujikawa time. Fig. 5(b) is here proposed as the present status of the region. If the method and data used in this paper are adequate, it is suggested that present Moho-discontinuity lies between the -15 to -20 km level with increasing depth northward. The Moho-discontinuity shows a fairly strong relief (10 km or more), whose troughs and swells correspond to the subsided belts and uplifted belts originated in Miocene. It is also suggested from Figs. 3 and 5 that the quartz diorite magma was generated from the lower crust in 15 to 20 km depth in the orogenetic epoch. The heat sufficient to melt the crust at such a shallow level might have been supplied from the mantle below.

Geology of the main seismic area in and around the town of Matsushiro, the northern part of Nagano Prefecture, central Japan, is investigated by field and literature surveys for the better understanding of the earthquake-swarm which is now taking place. The Matsushiro earthquake-swarm started at the beginning of August, 1965. Since then, the local seismicity has become more active with occasional rise and fall.

1. 地形的にその存在が推定されていた跡津川断層は,少なくとも庄川-神通川の分水嶺から北東へ常願寺川上流までたしかに存在する.長さ60km以上,部分的にゆるくを彎曲するがほぼ直線状で,その平均走向N60°E,断層面の傾斜はほぼ垂直,断層面上の断層条線はほぼ水平である. 2. この断層線に沿って,古生代の飛騨変成岩類から第四紀の河床堆積物までの地層および隆起小起伏面や段丘面などの地形面が変位している.この断層の変位の向きは多少の垂直成分を伴った右ずれである.この断層が示す変位の水平成分は断層の主部で約3km,垂直成分は,概して北側の相対的隆起でその量は1km以下である.すなわち,この断層は右横ずれ活断層である. 3. 第四紀の地層・地形面は古い時代のものほど大きく変位しているが,それ以前に生じた岩石では,時代が古くなっても変位量はそれ以上増加しない.したがって,現在この断層が示す変位量3kmは第三紀後期以後に生じはじめたと考えられる.数万年前に生成した河岸段丘が20m以上変位しているから,最近の数万年間における平均の変位速度は1~数m/1000年位と考えられる. 4. 段丘の変位や谷の喰違い現象は,この断層が最近地質時代に数十m以下を単位とする小刻みのほゞ同方向の変位を繰返してきたことを示している。また,この断層沿いにみられる断層崖などの断層地形は大地震時に生じる地形によく似ている.これらのことから,この断層の約3000mの変位量は地震時の変位の集積と考えられる.安政5年(1857)の飛騨地震はこの断層の最近の活動の1つと思われる. 5. 断層線上での谷の屈曲・転移のむきは概して右であるが,その量はその断層線から谷頭までの距離の大きな谷ほど大きい.このことは,この断層が活発な右ずれ変位を繰返していること,谷の喰違い地形は変位のむき・量を大略反映していること,谷の古さは断層線よりも上流の部分の長さにほゞ対応していること,を示唆している.このような谷の累進的転位現象の有無・程度は,未知の断層の活動性を知る1つの目安になると思われる.

松代地震の進展につれて松代町東部に地震断層の性格をもつた横ずれ地割れ群があらわれたので,その地割れ付近および周辺山地の地質を調べた. 1.調査地域内には,変位量数km以上の既存の大断層は存在しない.とくに今回あらわれた横ずれ地割れ群に沿つては,変位量数m程度の既存の小断層も見出せなかつた. 2.今回の地震であらわれた個々の地割れに沿つても,また,地割れ地帯に沿つても,最近地質時代に同様の変位が生じた形跡(地形的証拠)は見出されない. 3.鮮新世中期以降変位したことのない地質断層(滝本東断層)が地割れ帯に近接して存在するが,それに沿つては今回の地震で地割れは1つもあらわれなかった. 4.既存の断層に沿つて,断層性の変位が生じたたしかな例が1つだけみつかつたが,その断層は主な地割れ地帯からはなれているし,断層面のむきも変位のむきも特異である.松代地震における上記1.と2.の事実は,濃尾・北伊豆などの大地震に伴なつた地震断層の場合と全く異なつている.その意味で松代地震では従来いわれたような「古傷(大地質断層)の再活動」という表現は妥当でない.このような特異性と,松代地震が群発型であることを組合せると,大きな活断層が発達しない所(地質区)では群発地震の方が非群発型大地震よりもおこり易いらしいといえる.上記3の事実は,たとえ大断層があつても最近地質時代(この場合鮮新世中期以後)に変位を増加させた形跡のない断層は,今回のような地震の発生やそれに伴う変位に関与しないらしいという例になる.上記4の地震断層は,松代地震による直接の地震断層ではなくて,その周辺に生じた地盤の調整的変位の結果または地塊縁辺部での強い地震動の結果,地塊境界で生じた二次的変位(いわば間接的地震断層)であると思われる.

The Rikuu earthquake (M = 7. 2) occurred in the Mahiru Mountains in Tohoku district on 31 August 1896. Associated with the earthquake, reverse faults appeared on the surface along the western and the eastern feet of the Mahiru Mountains (Table 1 and Fig. 1), which are known as Senya and Kawafune earthquake faults (YAMASAKI, 1896), respectively. This was the largest on-land surface faulting of reverse fault type among events in historical time in Japan. These surface faults were re-studied.
