Seismologist william mccann and his colleagues have identified trouble spots in a remote region of alaska on the boundary between the north american and pacific at which there has been only minor activity to relieve pressure for 30 years more
地震學家威廉?麥卡恩和他的同事們準確地測出了在北美板塊和太平洋板塊接界的阿拉斯加的一個邊遠地區，是地震活躍區。Along with increase of pressure, the parameters such as velocity, amplitude, main frequency and quality factor of seismic wave change big gradually, while change very weakly with the change of temperature. through testing research for artificial crack and pore model, we conclude that crack density, azimuth, opening and the change of pore have obvious influences on speed, amplitude, attenuation ( or quality factor ) and main frequency of seismic wave etc. but, seismic wave dynamic characteristics are more evident than its kinematical characteristics for the change of crack and pore parameters. therefore, it offers reliable experiment foundation for detecting crack and pore by seismic wave kinematical characteristics ( such as amplitude, attenuation and main frequency etc. )
通過對人工裂縫和孔洞模型的超聲波實驗研究，可以認為：裂縫密度、方位、張開度和孔洞密度的變化對縱橫波的速度、振幅、衰減（或品質因子q ）和主頻率等參數均有明顯的影響，但裂隙參數的變化對地震波動力學特徵參數（振幅、衰減、主頻率等）的影響遠遠大於對運動學特徵參數（速度等）的影響，這為利用地震波的振幅、衰減和主頻率等屬性參數進行裂縫和孔洞特徵的檢測提供了可靠的實驗基礎。“ the question to be addressed in this debate is whether the accurate, reliable prediction of individual earthquakes is a realistic scientific goal, and, if not, how far should we go in attempting to assess the predictability of the earthquake generation process
「這場辯論中涉及的問題是，對個別的地震進行準確、可靠的預測是否是一個現實的科學目標，以及，如果不是的話，我們在嘗試對地震孕震過程的預測性評定方面應該走多遠？ 」
