| 摘 要： | 南阳盆地内发生的地震在仪器记录图上与其他地震波形有所不同,在直达横波正常出现后立即开始衰减,紧接着二次出现大振幅、大周期波形。对此进行了分析,证明在南阳地区地壳中存在一个硬度较大的界面,地震波到达该界面时发生反射,反射波与直达波叠加,即出现了第二个较大振幅的波形。

| Abstract: | The earthquake waves in Nanyang Basin are different from other areas,the S wave attenuated as soon as it arrived,and then appeared large amplitude and periodic wave.The big hard interface was found in Nanyang crust,and the seismic waves were reflected when they reached there,so the second large amplitude waves appeared when the reflected wave and S wave were superposed. |

| Keywords: | Nanyang Basin Special seismic phase Wave anomaly |
