    Abstract: PURPOSE: To judge whether earthquake data frame discrepancy is within an allowance range or not by selecting the width of an image as symmetry axis, dividing data around the symmetry axis, making the first and second data sets and comparing the data sets with a preset collating reference. CONSTITUTION: The results of earthquake testing groups are stored in an outside memory 210, prepared and modified to predict the image of earthquake data with specific symmetry around the axis. After they are modified, a device 200 is activated to read one frame of the earthquake data from a device 210 into an inside memory 220. An axis detector 240 accesses to the earthquake data and selects the axis as a symmetry axis. The maximum strength position is judged by a peak detecting technique. The earthquake data frame is sent to an edge detector 250 and a data point showing discontinuity in the data is identified, stored in an edge list and sent to a dividing means 260. The second edge list and the first edge list are collated by a collating device 160.
