| 内容記述 | 日本海側に発生した元禄7年(1694)能代地震・宝永元年(1704)岩館地震・寛政4年(1793)鯵ケ沢地震および文化7年(1810)男鹿地震について,新史料を加えた震度分布図を示し,地震の規模を検討した.一方,史料をもとに各地の津波の高さを現地調査し,津波の規模を考察した.1939年男鹿地震(M=7.0)の震度分布と比べると,鯵ケ沢地震の規模はM=7.2,能代地震・岩館地震・男鹿地震はいずれもM=7.0と推定される.これらのマグニチュード値は,従来のものより0.1～0.2大きい.鯵ケ沢地震では鯵ケ沢～深浦間で3～5mの波高が確められ,津波マグニチュードはm=1と推定される.岩館地震の潮位記録は,深浦～滝ノ間間で0.6～1.4mの津波が伴ったことを示唆しており,津波マグニチュードはm=Oとみなせる.また,能代地震・男鹿地震では20～30cmの津波があったと考えられる.震度・津波および地殻変動のデータを考え合せると,震源域は西津軽～男鹿沿岸にそって並び,震源の大きさは30～50kmと推定される. | |||||

| 内容記述 | Four earthquakes in 1694, 1704, 1793 and 1810 hit the Aomori-Akita district along the coast of the Japan Sea. From 12 to 400 persons were killed and 150 to 1200 houses were destroyed in each earthquake. These earthquakes were associated with tsunamis and remarkable crustal uplifts (0.9～2.2m). In this paper, the distribution of seismic intensity and the tsunami behavior are investigated with the aid of the field survey and newly collected data. The results are summarized as follows: 1) The magnitude of the 1793 Ajigasawa earthquake is inferred to be M=1.2, because the area of the seismic intensity was larger than the 1939 Oga earthquake (M =7.0). The distribution patterns of seismic intensity for the 1694 Noshiro, 1704 Iwadate and the 1810 Oga earthquakes are similar to that of the 1939 Oga earthquake, and these earthquake magnitudes may be regarded as M=7.0. 2) The inundation heights of the tsunami generated by the 1793 Ajigasawa earthquake were surveyed along the coast from Ajigasawa to Fukaura and found to be 3～5 meters (above M.S.L.). The tsunami magnitude (Imamura-Iida scale) was m=1, sug- gesting that the source area extended to the continental shelf. 3) According to the documents of sea-level change, the tsunami heights due to the 1704 Iwadate earthquake were 0.6―1.4 meters between Fukaura and Takinoma, suggesting that the tsunami magnitude can be regarded as m=0. For the 1694 Noshiro and 1810 Oga earthquakes, the wave-heights of about 20～30 cm were recorded at the mouths of the Yoneshiro River and Lake Hachiro. These behaviors suggest a tsunami magnitude of m=-1. 4) Source lengths ranging from 30 to 50 km are estimated for these earthquakes from the distributions of seismic intensity, tsunami and crustal deformation. The seismic sources were lined up along the coast from the West Tsugaru to the Oga Peninsula. | |||||
