This is a proposal for a new project in which is studied                        anomalous wavetrains associated with long-period spheroidal mode                overtones.  The proposed projects include: (A) Observation of                   anomalous wavetrains using Global Digital Seismograph Network                   (GDSN) and GEOSCOPE records.  We will use a stacking technique                  (UC contours) to separate modes and examine particle motion                     tracings to identify anomalies.  A compilation of data sets of                  anomalous wavetrains caused by the path effects is essential.                   (B) Analysis of path-dependent dispersion relations.  Our                       preliminary study of anomalous surface wave overtones indicates                 that this problem is spatially dependent on the path.  In this                  case the local dispersion relation does not determine the modes                 of waves.  Instead we should consider an expression that depends                on the properties of the mode over its entire range of wave                     propagation, so we can use the results to construct the overall                 eigenvalues for the system.  (C) Collaboration through a work                   station network.  Our proposed study of surface wave propagation                requires a knowledge of the earth's structure which may also be                 supplied by tectonic, geodetic and geological studies.  We will                 exchange data, information and ideas related to the earth's                     structure with scientists in different fields through a work                    station network.
