【摘要】 选用经多次筛选的23次定位地震及130组高精度地震参数进行研究计算,用直达波时距方程计算了研究区直达纵、横波的平均传播速度(-pν-=6.13 km/s-、ν-s=3.52 km/s)。利用反射纵横波得出地壳厚度HP11、HS11,莒县—郯城地区平均地壳厚度为34.8 km。更多还原

【Abstract】 Using travel-time equation of direct wave,the average velocity of direct P-wave and direct S-wave(ν-p-=6.13 km/s,ν-s-=3.52 km/s) in Juxian-Tancheng area are calculated based on 23 Multiple screened earthquakes and 130 sets of high-precision seismic parameters.Then,the crustal thickness(HP11,HS11) of the study area are calculated using the reflection P-wave,reflection S-wave.The results indicate that the average crustal thickness in Junan-Tancheng area is about 34.8 km.更多还原
