作者根据位错模型导出了震级不仅与震中烈度和震源深度有关,而且与极震区面积有关。震中烈度通过应力降和震级联系起来,而极震区面积则通过位错面的面积或震源体积和震级联系起来,使震级与烈度的物理联系更加明确。 用我国的61个浅源地震资料,用逐步回归方法计算出震级M与震中烈度I 0、极震区面积（面积单位为平方公里）A 0的关系为: M=3.53+0.039I 02+0.0178（Ig A 0） 3,还分别计算出震级与6-8度区面积A 6、A 7、A 8的关系为: M=3.63+0.72 Ig A 6, M=5.34+0.718（Ig A 7）·（IgIg A 7）, M=5.92+0.104（Ig A 8） 2。并外推出震级与5度区面积A 5的关系为: M=3.03+0.72 Ig A 5。 利用这些关系式来确定历史地震震级比仅考虑震中烈度来确定有较好的效果。 相似文献

用体波合成地震图与观测地震图拟合的方法确定了渤海地震（1969.7.18. M=7.4）和云南永善地震（1974.5.11. M=7.1）的震源参数.针对震中距为30至90的远震 P+pP+sP 波,采用 WKBJ 近似和实路径积分,做出了20个 WWSSN 台站的渤海地震和7个WWSSN 台站的永善地震的全波理论合成地震图.与实际记录到的长周期垂直分量地震图进行比较,以试错法确定两大地震的震源参数如下:渤海地震:h=25km,=205,=85,=-145,M0=2.41019Nm,R=25,L=36km,vR=6km/s;永善地震由两个同时发生的 h=15km 的子破裂组成,其一为=45,=65,=0,M0=1.91019Nm,R=225,L=10km,vR=1km/s;其二为=200,=75,=170,M0=1.31019Nm,R=30,L=23km,vR=2km/s.这里 h 为震源深度,为走向,为倾角,为滑动角,M0 为总地震矩,R 为断裂扩展方向,L 为断层长度,vR 为破裂传播速度. 相似文献

在假定地震动物异常行为(SAAB)是对地震电信号(SES)的电生理反应的前提下,通过施加电场、实验再现了神户地震所报道的SAAB————蚕及鱼的定向排列．由于垂直于电场时动物体内骨格肌的阻抗较平行时大,动物表现出沿垂直于电场方向排列的行为．基于偶极电荷q源于地震应力(t)的变化,提出了一断层的电磁模型:dq/dt=－(d/dt)－q/,其中是一表征电荷生成的常数,比如压电系数;为介电常数,为花岗岩的电阻率．一长2a且位错或破裂时间为的断层,由于应力的变化将产生脉冲状的偶极电荷(面密度):+q(t,x)和－q(t,x+2a),或由地震矩M0而给出偶极矩P(t)=2aAq(t)=M0［/(－)］(e－t/z－e－t/)．断层位错D、位错速率D和应力降满足=D/D=(/0)(a/)．断层域的电场强度F及电流密度J可由F=q/及J=F/得到．若为水的电阻率,则可得到J=0.1～1 A/m2,该值足以引起动物的异常行为．由P(t)所产生的近场甚低频(ULF)波可解释与距离R成反比的SES． 相似文献
