Seismic on the edge – a 3D transition zone seismic survey from concept to final volume

Seismic evidence for an inner core transition zone

Seismic waves that traverse Earth's inner core along north-south paths produce unusually broad pulse shapes at long periods (compared with waves along east-west paths) and reflections from below the inner core boundary at short periods. The observations provide compelling evidence for a seismic velocity discontinuity along north-south paths about 200 kilometers below the inner core boundary sep...

Notes on seismic hazard sensitivity studies for Eastern Tennessee Seismic Zone 3 March 2008 -

Could you please make sure that these documents are part of the record for the industry proposal to resolve the ETSZ issue that was agreed upon by the NRC on our last telecon on March 4 th? If it would help, I can send these in a letter to you as well. Our understanding is that the NRC agrees the proposed scope is satisfactory. Also, the industry will provide the study to the NRC for review no ...

Extracting Seismic Profiles from Background Seismic Signals

The idea of obtaining the seismic trace representing the impulse response at one receiver due to a source at another receiver has discussed by many authors. Jon Claerbout (see e.g. Rickett and Claerbout, 1996; Claerbout, web) introduced the concept to seismology. It has been investigated in the laboratory by Lobkis and Weaver (2001), observed in seismic data by Campillio and Paul (2003), and in...
