摘要

人们对 1895 年 4 月 14 日发生在斯洛文尼亚卢布尔雅那地区的地震(震级 6.1 级)仍未完全了解。这项工作的目的是通过反演最新的地震烈度数据集(使用 EMS-98 评估)来获取有关震源的信息。这项工作是通过自动非线性地球物理反演 KF-NGA 来完成的,该反演使用了 Niching 遗传算法,已在其他文章中介绍过。这次地震造成的破坏分布并不均匀,相邻地点之间往往存在明显的烈度差异。对地震烈度、震中距 离和震中地质性质的统计分析显示了一些震点效应。尽管如此,得出的解决方案与区域地震构造一致,即几乎是纯粹的倾滑机制:走向 282°±5°,倾角 38°±7°,倾斜角 86°±9°(由于 KF-NGA 转换的内在模糊性,倾斜角为 ±180°)。由于前倾角接近 90°,焦距机制的两个平面之间几乎完全模糊。因此,我们的解决方案具有迪纳拉方向,既可能与向东北倾斜的断层面有关,也可能与向西南倾斜的断层面有关。

The 1895 Ljubljana earthquake: source parameters from inversion of macroseismic data

The 14 April 1895 (Mw 6.1, in the area of Ljubljana, Slovenia) earthquake is still not fully understood. The aim of this work is to derive information about its source from the inversion of an updated dataset of intensities (evaluated with EMS-98). This was done via automatic non-linear geophysical inversion KF-NGA, which was performed using a Niching Genetic Algorithm and has been presented in other articles. The distribution of damage caused by this earthquake is not homogeneous and often shows significant intensity differences between neighbouring sites. Statistical analysis of the intensities, epicentral distances and geologic nature of the sites suggests some site effects. Nevertheless, the resulting solution is consistent with regional seismotectonics, i.e. an almost pure dip-slip mechanism: strike 282° ± 5°, dip 38° ± 7°, rake 86° ± 9° (± 180° because of the intrinsic ambiguity of the KF-NGA-inversion). Since the rake angle is close to 90°, there is an almost perfect ambiguity between the two planes of the focal mechanism. Therefore, our solution has a Dinaric direction and could be associated either with a fault plane that dips NE or with one that dips SW.
