Figure 8
Rotation of the split foundation of the east end-building. The accelerometers were mounted anti-parallel with a distance d/2 from the center of the foundation and the signals were added. The difference between d = 1 m and d = 5 m at daytime is not clear. Both measurements were made with a long time interval, and there is no sign whether a tractor has produced additional signals for the d = 5 m measurement or not.
