Geophysical survey (GPR, ERT, magnetic) on active faults in Slovenia and Italy

The transition zone between the Southern Eastern Alps and the Dinarides is situated in western Slovenia and northeastern Italy. Here, a system of mainly NW-SE trending, right-lateral strike-slip faults accommodates the shortening between the Adriatic Plate and Eurasia. Due to the low deformation rates, geodetic techniques and seismology provide only limited insights into the activity of those faults. Geomorphological studies are confronted with problems arising from the low fault slip rates, distributed deformation, and unfavourable conditions due to the karst environment. One way to overcome these problems is the use of paleoseismology, i.e. the excavation of active faults to study their earthquake history and slip behaviour. A prerequisite for paleoseismological trenching is knowledge on the precise location of the fault trace and the availability of a suitable sediment record. […]

南东阿尔卑斯山脉与迪纳瑞山脉的过渡区域位于斯洛文尼亚西部和意大利东北部。该区域主要由西北-东南走向、右旋走滑断层系承受亚得里亚板块与欧亚大陆之间的缩短。由于变形速率较低，地测技术和地震学仅能对那些断层的活动提供有限的见解。地貌学研究面临着由低断层滑动速率、分布性变形以及由于喀斯特环境造成的不利条件所带来的问题。克服这些问题的方法之一是采用古地震学，即挖掘活动断层以研究其地震历史和滑动行为。古地震学沟渠挖掘的前提是掌握断层线精确位置以及适宜的沉积记录的可用性。
