I will update a column of the NIED e-mail magazine which I wrote a long time ago because the content is not faded with time. (I will do this step by step in Japanese and English) I will also add comments to update the situation.

NIED-DIL e-mail magazine: Matsushiro Earthquake Center
■ Matsushiro Earthquake Center ■
There is an organization called Matsushiro Earthquake Center in Matsushiro, Nagano Prefecture in Japan. The Center was established in February 1967 at the Japan Meteorological Agency in Matsushiro Town, Nagano Prefecture (now Nagano City) based on the Matsushiro Seismological Observatory which was established in 1947. The background of this establishment is that between August 3, 1965, and April 17, 1966, insensitive earthquakes, seismic intensities 5 and 4 were observed three times each and a total of 6,780 earthquakes were detected in the Matsushiro town area. This severe earthquake activity has become a major social problem.
It is famous that Mayor Nakamura at that time said that he wanted to learn and research more than things and money, and that was a starting point of the center. The center is also well known as the location which was planned to build the imperial general headquarter at the end of the second world war. Besides, It is known that the experience gained from the observation of the earthquake has dramatically influenced the progress of earthquake prediction and disaster countermeasures today.
The author is organizing the records of the discourse at the time with the cooperation of the Japan Meteorological Agency’s Earthquake Observatory (Matsushiro Seismological Observatory) as the Disaster Information Office. I am surprised at the fascinating records. The fact that Matsushiro city was working to build a disaster-resilient town in the wake of an earthquake throughout the city is lively communicated. For example, there was not only research on the earthquake itself but also research on the health status of students, including psychological aspects from nearby schools caused by a swarm. This was due to the cooperation of Matsushiro health centers and hospitals. It does not stop there. Members were active in the front lines of various fields at the time, such as landslide surveys caused by earthquakes and the impact on water supply facilities during earthquakes, reports from various perspectives.
I am sorry that the format etc. is still insufficient, but I am starting to release these records on the HP in hopes that you can see it in a provisional form. Please see if you have time.
Now you can not access, but you can ask NIED DIL to have information.
