In this region, the depth of the Moho interface decreases from about 28 km in the west to about 20 km in the east. The transition between continental and oceanic crusts is reflected in the variation of the depth of the Moho interface. There are several NW trending faults in the Taiwan Strait, including the Ningde-Sandiaojiao fault zone (宁德-三貂角断裂带), the Taichung-Jinjiang fault zone (台中-晋江断裂带), and the Bashi fault zone (巴士断裂带).沈金瑞 许世远 傅文杰 台湾海峡地区横向构造及其对东南沿海地震的作用 大地构造与成矿学 2009 33 4 535–541 http://www.cnki.com.cn/Article/CJFDTotal-DGYK200904008.htm 1 December 2018 zh-cn 27 August 2019 https://web.archive.org/web/20190827044831/http://www.cnki.com.cn/Article/CJFDTOTAL-DGYK200904008.htm dead In addition, there are several faults in the NE direction, including the Binhai Fault Zone (or the Littoral Fault Zone) (滨海断裂带)."南澎列岛及邻近海域地质地貌与灾害地质分析" by 詹文欢, 张乔民, 孙宗勋, 唐诚, and 丘学林詹文欢 张乔民 孙宗勋 唐诚 丘学林 南澎列岛及邻近海域地质地貌与灾害地质分析 热带海洋学报 2002 21 1 11–17 http://www.cqvip.com/qk/96022a/200201/5977085.html 344004/7739 1 December 2018 zh-cn Some sources suggested that the earthquake was related to the activity of the Bashi fault system. However, there are still disputes over whether the fault plane should have been in the NW or the NE direction. A paper of Fujian Seismological Bureau showed that the earthquake was caused by left-lateral strike slip of a normal fault. The earthquake had a maximum slip of 14 m in the hypocentral region. The source duration was about 4 s, which is short for an event with magnitude about w 6.7. From the slip amplitude and the source duration, it was suggested that this earthquake began as a breaking of a strong asperity with low dynamic friction, had high stress drop, and was stopped by large friction around the asperity.The 16 September 1994 Taiwan Strait earthquake: A simple rupture event starting as a break of asperity Physics of the Earth and Planetary Interiors 107 4 269–284 1998 Zheng Tian-yu Ai Yin-Shuang Chen Qi-zhi 1998PEPI..107..269Z 10.1016/S0031-9201(98)00085-5 Damage The intensities recorded in Taiwan were shindo 4 in Penghu, 3 in Kaohsiung, and 2 in Taipei.

Effects of Seismicity in the Taiwan Strait on the Southeast Coastal Area of the Chinese Mainland Tsunami A tsunami was triggered by the earthquake. The heights of the tsunami were recorded as 38 cm in Penghu, Taiwan and 18 cm in Dongshan, Fujian, China.
