琵琶湖の西岸付近の湖底堆積物には肉眼で確認される砂層以外にもシルトを主とする細粒の粒子からなる湖底地滑りを起源とする堆積物が多くはさまれている。これらのタービダイトの堆積年代を重量堆積速度を基に推定した結果, 歴史地震と対応する事が明らかになった。湖底地滑りを起こした地震の震度の下限値は, 琵琶湖においては気象庁震度階のIVとVのそれぞれの下限値の中間である。この震度を加速度表示した場合, 約44galに相当する。これはMM震度階のVIとVIIの境界の加速度に相当する。

(1) A local, but severe earthquake occurred near Nagaoka City, Niigata Prefecture, on February 2nd, 1961. Its epicentral area was in the western part of Nagaoka City, being not very far from the area stricken by the Sekihara Earthquake of 1927. Figs. 2 and 3 show the epicenter and isoseismal lines of the earthquake (after JMA, Niigata Meteorological Observatory). According to the JMA, the epicenter was located at 37°27'N and 138°49'E, and the depth of the origin about 10 km. The magnitude of the earthquake was 5.0. (Gutenberg-Richter)

1961年8月19日岐阜,福井,石川3県境界付近に発生した北美浜地震にともなう余震群を,本震震央南南西30kmの岐阜県郡上郡八幡町において8月27日より約1ケ月間磁気テープ記録による多成分観測装置によつて観測した.辺長1kmにちかい3点観測によつて初詣の到来方向,みかけの速度をもとめ余震群の分布を現地でただちに推定することができたが,それによると余震域は本震震央の西方にひろがるごくせまい面積をしめ,深度はO~25kmの地殼内にかぎられることがわかつた.余震域の面積A(km2)は本震の規模(M=7.2)から宇津・関の公式logA=M-4で推定されるものにくらべいちぢるしくせまい.なお余震群以外の局地的小地震が観測されたことも注目にあたいする結果である.|After the Kita Mino (North Mino) Earthquake of August 19th, 1961, we hurried to Hachiman, Gujo County, Gifu Prefecture, Central Japan, about 30 kms south-east of the epicenter to observe its aftershock activity for several weeks. Tripartite stations were occupied, as shown in the map of Fig. 1, near the temporary observation room at Gujo High School and from Aug. 27th to Sept. 20th the observation were executed almost continuously.

The area around Mt. Gankyoji-yama, 45 km east of Fukui City and 70 km north of Gifu Gity, was attacked by a severe earthquake at 14 h 33 m on August 19, 1961 (The earthquake was later named as Kita Mino Earthquake). In this area, in addition to the damage done to houses and stone walls, fissures were opened on narrow ridges. Many rock fall and earth fall took places on the steep cliffs.

Detailed rupture processes of six intraplate earthquakes in Japan, the 1961 Kitamino earthquake, the 1969 GifuKen-Chubu earthquake, the 1974 Izu-Hanto-Oki earthquake, the 1975 OitaKen-Chubu earthquake, the 1980 Izu-Hanto-Toho-Oki earthquake, and the 1984 NaganoKen-Seibu earthquake, are compiled and compared to each other to make clear common features of an earthquake rupture process. The rupture processes are obtained by waveform inversion using strong motion seismograms in previous studies. Five of these rupture processes are also compared with distributions of precisely determined aftershocks. Earthquakes with relatively smooth rupture propagation, such as the 1974 Izu-Hanto-Oki earthquake and the 1961 Kitamino earthquake, represent smoother slip distribution than earthquakes with relatively irregular rupture propagation, such as the 1969 GifuKen-Chubu earthquake and the 1980 Izu-Hanto-Toho-Oki earthquake. It is also recognized that aftershocks of magnitude greater than 4 do not occur in the large slip area. Most large aftershocks take place near the edge of the large slip region and in the small slip region. Aftershocks also tend to cluster near the edge of the large slip region. These results are very consistent with numerical experiments of dynamic rupture, so it is suggested that the relation between aftershocks and coseismic slip pattern obtained in this paper hold generally for earthquake rupture processes. A clear delay of rupture propagation occurs in the large slip area during the 1969 GifuKen-Chubu earthquake: on the other hand, the small slip area in the 1980 Izu-Hanto-Toho-Oki earthquake is characterized by a deceleration of rupture propagation. The large slip area in the former case is interpreted as a barrier which resisted fracturing at first and was broken with a high stress drop. In the latter case, mechanical weakness due to volcanic structure located around the source region, seems to have affected the rupture process. A similar geological condition may have affected the rupture process of the 1978 Izu-Oshima-Kinkai earthquake which occurred about 10 km south of the 1980 Izu-Hanto-Toho-Oki earthquake.

The fact that the pictures of the Imperial family of Japan were called "goshin-ei", and were treated as the icons of the religious observance at schools in modern Japan was pointed out by a lot of preceding studies on the "goshin-ei". According to these precedent studies, on festival days of the Imperial family, school students at the prewar days were made to worship pictures of the Imperial family that Japanese government sent to many schools, and through these religious observances at schools, the government succeeded in cultivating the respects for the Imperial family in Japanese people. By the way, many pictures and portraits of the Imperial family of Japan were sold by private merchants, and were printed in newspapers and magazines frequently at prewar days. But preceding studies on the "goshin-ei" treated the pictures of the Imperial family that the government sent to schools exclusively, and didn't refer to the pictures and portraits of the Imperial family sold or distributed by private merchants and the mass media. The purposes of this paper are to elucidate the activities of the Japanese government, the mass media and people around gravures of the Imperial family of Japan in newspapers and magazines at prewar times, and to make clear the mentalities to the Imperial family that these gravures cultivated in Japanese people.
