歴史地震の研究 (4) : 慶長 9 年 12 月 16 日(1605 年 2 月 3 日)の地震及び津波災害について Investigation of Historical Earthquakes (4) : Earthquake and Tsunami Damages by the Keicho Earthquake of February 3,1605
The earthquake and tsunami damages caused by the Keicho earthquake of 1605 are investigated from old documents collected to understand the damage locality and the occurrence characteristics of an earthquake in off Tokaido districts. The distribution of seismic intensity and tsunami inundation heights are also studied. Tokaido and Nankaido districts along the Pacific coasts were hit by the tsunami of this earthquake. Most severe inundation heights are estimated at about ten meters in Tokushima Prefecture and Hachijo Island. Two epicenters of the Keicho earthquake are assumed as longitude 137.8°E, latitude 34.0°N in Enshunada and longitude 134.9°E, latitude 33.3°N, off Kii Peninsula, respectively. It is estimated that about five thousand houses were destoryed and about several thousand peoples were drawned by the Keicho earthquake and tsunami. The magnitude of this earthquake is estimated at 8.0-8.1 for off Tokaido and 8.1-8.2 for off Nankaido, respectively.
