Abstract
Recently it was experimentally shown that rock crash by static pressure caused the microwave emission, and this result suggests the microwave would be emitted on the occasion of earthquakes. In order to verify this hypothesis, we have developed the computer system for analyzing the huge satellite database of Institute of Space and Astronautical Science (ISAS). The database includes the orbital parameters and the communication data of all satellites launched by ISAS. As a result, we have found out some anomalies in the data of the S-band (2GHz) microwave power level as for ASCA satellite by this system.
