A developing plate boundary: Tianshan-Baykal active tectonic belt

It is obvious that a great amount of strong earthquakes in central Asia occurred densely along Tianshan-Baykal belt; however, none huge continuous fault has been revealed on the surface along the belt. It caused academic argument related to their relationship. The authors analyzed its seismic activity in terms of seismicity in time-space domain, zoning feature, stress field, and recurrence period of earthquakes. In addition, we studied the Bouguer gravity and isostatic anomaly, and calculated the distributi...

Abstract:

It is obvious that a great amount of strong earthquakes in central Asia occurred densely along Tianshan-Baykal belt; however, none huge continuous fault has been revealed on the surface along the belt. It caused academic argument related to their relationship. The authors analyzed its seismic activity in terms of seismicity in time-space domain, zoning feature, stress field, and recurrence period of earthquakes. In addition, we studied the Bouguer gravity and isostatic anomaly, and calculated the distributi...
