This proposal requests support for fundamental study of                    seismic wave excitation by earthquakes of anomalously long                      duration.  They are particularly interested in the possibility                  that low-velocity deformation events occur with characteristic                  time scales too long to radiate significant high-frequency seismic              energy, but short enough to excite low-frequency free                           oscillations.  To test this hypothesis, they have developed a                   novel method capable of detecting low levels of free-oscillation                excitation superposed on background noise, and they propose to                  apply this detector to ten years of GDSN data.  Once a low-                     frequency event is detected, they will derive its location, total-              moment spectrum and source-mechanism spectrum using methods                     developed under an expiring NSF grant.
