| 摘 要： | 分析了震动京津的文安地震的特点:余震微小,最大仅1.5级,属于孤立型地震;震区烈度偏低、有感范围大;宏观震中与微观震中相差10余公里;震源较深;具有较大的正断层错动分量。对此作出初步解释,并认为可能是岩石圈减薄的新证据

| Abstract: | Through analysis, we found that the Wen'an earthquake has the following characteristics: the aftershocks are small with the biggest of only M 1.5, belonging to the isolated type earthquake; the earthquake intensity is low, but the perceptible area is relatively large; the macro-epicenter is over 10km away from the micro-epicenter; the hypocenter is deep; and the fracture of earthquake shows a normal fault slip. The explanation for these characteristics is presented, which can be regarded as a new evidence for lithospheric thinning. |
