Abstract

The Earthquake Research Committee of the Headquarters of Earthquake Research and Promotion estimated the probability of an earthquake of magnitude around 7.0 occurring during the next 30 years as 70%. This is based on five earthquakes that occurred in the southern Kanto region (i.e., the 1894 Meiji-Tokyo earthquake, the 1921 and 1922 Ibaraki-ken Nanbu earthquakes, the 1922 Uraga-channel earthquake and the 1987 Chiba-ken Toho-Oki earthquake). However, it has been revealed that the Kanto region is situated on complicated tectonic conditions due to subduction of the Philippine Sea Plate and the Pacific Plate beneath the continental plate, and that various types of earthquake occur. Therefore, it is necessary to classify these earthquakes into interplate and slab earthquakes, and to estimate their recurrence intervals. In this paper, at the outset of such studies, we review previous studies on two earthquakes (the 1894 Meiji-Tokyo and 1895 Ibaraki-ken Nanbu earthquakes) that occurred in the Meiji era and collect the data.
