Alp01 and Alp02 are the longest profiles recorded during ALP 2002, a large international seismic refraction wide‐angle reflection experiment undertaken in Eastern Alps 2002. crosses Alpine orogen from north to south, thus providing cross section mainly affected by collision between Europe Adriatic microplate. extends Pannonian basin, supplying evidence on relation crustal structure tectonic escape basin. During this experiment, 363 single‐channel recorders were deployed along these with an...
Results are presented of the first airborne LiDAR survey ever flown in Europe for purpose mapping surface expression earthquake‐prone faults. Detailed topographic images derived from data Idrija and Ravne strike‐slip faults NW Slovenia reveal geomorphological structural features that shed light on overall architecture kinematic history both fault systems. The 1998 M W = 5.6, 2004 5.2 Fault earthquakes historically devastating 1511 6.8 earthquake indicate systems pose a serious seismic hazard...
Abstract Located at the northeastern corner of Adria microplate, Alps‐Dinarides junction represents a key region for understanding how microplate interacts with stable Europe. However, little is known on present‐day deformation imposed by rotation absorbed across Dinarides. Using morphotectonic analysis based satellite and aerial images, accurate topographical maps, digital elevation models combined field investigations, we mapped in detail three main active faults Northern Geomorphic...
Abstract. The town of Kobarid is located in one three areas with the highest seismic hazard Slovenia. It was hit by several 1976–1977 Friuli sequence earthquakes and recently 1998 2004 Krn Mountains which caused damage intensity up to VII EMS-98 scale. a small basin filled heterogeneous glaciofluvial Quaternary sediments site effects due soft are expected. existing microzonation based on surface geological data only inadequate, no borehole or geophysical available that would allow modelling...
Abstract. The town of Idrija is located in an area with increased seismic hazard W Slovenia and partly built on alluvial sediments or artificial mining smelting deposits which can amplify ground motion. There a need to prepare comprehensive microzonation the near future support risk assessment. To study applicability microtremor horizontal-to-vertical spectral ratio (HVSR) method for this purpose, 70 free-field measurements were performed 0.8 km2 50–200 m spacing between points. HVSR...
Abstract Knowledge about the crustal thickness is one of key elements in reconstruction regional tectonic history. The Dinaric mountain belt most enigmatic segments Alpine‐Mediterranean collision zone, characterized by large variations and not studied sufficiently. We present a new Moho depth map for wider Dinarides region which was created using teleseismic earthquake recordings from 87 permanent temporary seismic stations region. Teleseismic data were analyzed receiver function method to...
Abstract. The AlpArray Gravity Research Group (AAGRG), as part of the European program, focuses on compilation a homogeneous surface-based gravity data set across Alpine area. In 2017 10 countries in realm agreed to contribute with for new field an area spanning from 2 23∘ E and 41 51∘ N. This relies existing national databases and, Ligurian Adriatic seas, shipborne Service Hydrographique et Océanographique de la Marine Bureau Gravimétrique International. Furthermore, Ivrea zone Western...
Slovenia is located on an active convergent boundary between the Adriatic microplate and Eurasian plate, characterized by compressive fault systems moderate seismicity. Relatively high seismic hazard in W related to Dinaric Fault System of dextral strike slip faults. After Idrija fault, second most important more than 100 km long Raša Fault. Its activity has been estimated previous geomorphological studies rate at about 0.7 mm/year. Due its length, relatively large earthquake...
On Kranjsko polje in central Slovenia, carbonate conglomerates have been dated to several Pleistocene glacial phases by relative dating based on the morphostratigrafic mapping and borehole data, paleomagnetic 10Be analyses. To define how age of determines geomorphological characteristics karst surface features, morphometrical distributive spatial analyses dolines were performed three test sites including old, middle, young conglomerates. As are covered a thick soil cover show strong human...
The region of Ilirska Bistrica is one the most seismically active areas Slovenia, where 15 damaging earthquakes with maximum intensity equal or greater than V EMS-98 have occurred in last 100 years. These shown that strong site effects are characteristic parts town built on soft Pliocene clay and sand overlain by Quaternary alluvium. Since there a lack boreholes geophysical earthquake data, microtremor horizontal-to-vertical spectral ratio (HVSR) method was applied to 250 m dense grid...
Abstract. The 12 April 1998 Mw = 5.6 Krn Mountains earthquake with a maximum intensity of VII–VIII on the EMS-98 scale caused extensive environmental effects in Julian Alps. application scales based mainly damage to buildings was limited epicentral area, because it is high mountain area and thus very sparsely populated. On other hand, natural environment were prominent widespread. These facts introduction new Environmental Seismic Intensity (ESI 2007) motivated research aimed evaluate...
A review of geological and seismotectonic investigations conducted in the two decades after 12 April 1998 earthquake Krn Mountains, according to its magnitude strongest Slovenia 20th century, is given. Many these studies have wider scientific meaning than expected from size earthquake. This was first case that a strong undoubtedly related particular fault. Seismotectonic seismogenic Ravne fault revealed it an actively propagating strike-slip growing by interaction individual right stepping...
The earthquake on 12 April 1998 at 10h 55min UTC (12h local daylight-saving time) in the Krn mountains was according to its magnitude (mb=5.3, Mm =5.3, MLV=5.6, MW=5.6, MS=5.7, MWA=6.0) among strongest Slovenia 20th century. Its epicentre situated about 8 km south-east from town of Bovec and hypocentral depth 7.6 km. maximum intensity VII-VIII EMS-98 observed four villages. Mainly older buildings, built rubble simple stone, were damaged. A temporary network portable stations deployed...
Overview of extensive seismological studies Krn Mountains earthquakes performed in two decades is given. Detailed macroseismic by using a new European Macroseismic Scale EMS-98 showed large variations damage to buildings due the influence very heterogeneous sediments and partly also differences source radiation pattern. Site effects were carefully studied it was proven microtremor HVSR method that soil-structure resonance severely enhanced many places. Particularly important seismotectonic...
