Both an emergency earthquake prompt report via a digital broadcast and an emergency earthquake prompt report via a wide-area wireless communication system are utilized, and if one of the two emergency earthquake prompt reports is received and thereafter the other emergency earthquake prompt report cannot be received within a predetermined time period, then it is determined that the former emergency earthquake prompt report is an erroneous report.
