摘要

亚得里亚海南部的部分，毗邻穆尔热地区(意大利南部的阿普利安前陆)，被认为主要是地震。最近的2018年3月23日发生在布林迪西(普利亚地区)附近的地震(3.7 Mw)，使我们有机会重新考虑来自不同来源的数据(仪器记录，历史记录和古地震解释的地震)，这些数据表明亚得里亚海的这一部分发生了一些中等地震冲击。本研究基于ViDEPI项目对公共域地震剖面和勘探测井资料的重新解释，重点关注震源区域第四纪活动断层的识别。一条以倾滑运动为主的s向断层可能是孕震源。其几何形状与INGV (Istituto Nazionale di Geofisica e Vulcanologia)计算的断裂面解和震源深度一致。

In search of the seismogenic fault of the March 23rd 2018 earthquake (Mw 3.7) near Brindisi (Puglia, Southern Italy)

The portion of the southern Adriatic Sea, adjacent to the Murge area (Apulian Foreland, Southern Italy), is considered mainly aseismic. The recent March 23rd 2018 earthquake (Mw 3.7), occurred near Brindisi (Puglia Region), giving us occasion to reconsider data coming from different sources (instrumentally-recorded, historically-documented and palaeoseismologically-interpreted earthquakes), that suggest some moderate seismic shocks in this portion of the Adriatic Sea. The present study, based on the re-interpretation of public domain seismic profiles and exploration well logs available in the ViDEPI Project, has been focused on the recognition of faults with Quaternary activity in the epicentral area. A S-dipping fault, with a main dip-slip component of movement, is suggested to be the seismogenic source. Its geometry is consistent with the fault plane solution and the depth of the hypocenter calculated by the INGV (Istituto Nazionale di Geofisica e Vulcanologia).

期刊介绍： Geologia Croatica welcomes original scientific papers dealing with diverse aspects of geology and geological engineering, the history of the Earth, and the physical changes that the Earth has undergone or it is undergoing. The Journal covers a wide spectrum of geology disciplines (palaeontology, stratigraphy, mineralogy, sedimentology, petrology, geochemistry, structural geology, karstology, hydrogeology and engineering geology) including pedogenesis, petroleum geology and environmental geology. Papers especially concerning the Pannonian Basin, Dinarides, the Adriatic/Mediterranean region, as well as notes and reviews interesting to a wider audience (e.g. review papers, book reviews, and notes) are welcome.
