EARTHQUAKE PRECURSOR PHENOMENA AND CRUSTAL BUCKLING

Su Gang Xu Shiaoxie  
Being introduced to investigate seismic pattern, crustal buckling can explain many earthquake precursor phenomena according to the layered structure of crust. After a discussion on crustal buckling, whether the continental crust has possession of producing buckling condition and the relationship between crustal buckling and earthquake, we conclude thin layer in crust will be bended at first due to its low critical yield stress and there arises small shocks and seismic anomalies, which results from tbe intensification of the regional crustal movment and is named regional precursors. A considerable medium-long term precursors likely belong to the sets. Thick layer in crust corresponding to large quakes possesses higher critical yield stress, so it influences late upon the precursor field (excluding dilatancy). For that reason, the remarkable precursors from source of a large quake mainly are the one of short and immediate term. Linking with the relationship of precursor field and earthquake source, we can see that crustal buckling causes seismicity to grow big from being small before a large quake. It is identical with the R-T figure of regional small quake befores Tangshan earthquake of magnitude 7.8.There are two significant points which crustal buckling gives rise to earthquake precursors,1).Instability will provide the basic background for variation of precursor field and instable fracture;2) .Jumping, initiation and development of buckling will be reflected intensively in precursor observations. In addition, jumping, external cause modulation and triggers of quake all have relation of it. Therefore crustal buckling is one of the mechanics basis of earthquake precursor.
