Hi,
I need the digitized data (Acceleration time history) of 1968 Tokachi-Oki Earthquake (Hachinohe harbor).
Here you can see the graph of this record (Acc. time history) that used in this article: Article Centrifuge model tests and effective stress analyses of offs...
And also an old report of this event is available in Port and Airport Research Institute of Japan website: [pari.go.jp] (Strong-Motion Earthquake Records on The 1968 Tokachi-Oki Earthquake And Its Aftershocks)
I wonder if someone can help me find this record. Thanks.
