大正3年3月28日羽後平鹿郡の地震の震央について

抄録

The epicenter of the Numadate Earthquake on March 28, 1914 (JMT) has been reported to be at 140°.9E, 39°.8N in the “Rika-Nenpyo”, which is a standard reference on big earthquakes in Japan. However, this location is inconsistent with the distribution of damage or with other evidences. The epicenter is relocated in this paper based on the newly collected reports about damage as well as the S-P times at several stations. Both the macroseismic and instrumental results give the epicenter at 140°.4E, 39°.2E.
