Research Abstract	A rotational seismometer based on the 'pinning effect' of high Tc superconductive materials has been developed and prototyped in this study. The characteristics of the prototype seismometer, such as stability, resolution are studied and the test observation in the laboratory has been performed. Throughout these studies, it was confirmed that the aimed specifications of the instrument has been achieved and its ability to observe rotational seimic motion caused by near earthquakes has been demonstrated.
