Article
On 29 December 2020, a shallow earthquake of magnitude Mw 6.4 struck northern Croatia, near the town of Petrinja, more than 24 hours after a strong foreshock (Ml 5). We formed a reconnaissance team of European geologists and engineers, from Croatia, Slovenia, France, Italy and Greece, rapidly deployed in the field to map the evidence of coseismic e...

Presentation
Full-text available
After the earthquake of 29/12/2020 in Petrinja (ML6.2, ImaxVIII-IX EMS), an attempt was made to characterize the active structure associated with the earthquake. As a first step towards this goal, we performed a geomorphological analysis in order to contribute to the identification and characterization of the surface expression of the active Pokups...

The 29 December 2020, Mw 6.4 Petrinja earthquake nucleated at a depth of~10 km in the Sisak-Moslavina County in northern Croatia,~6 km WSW of the Petrinja town. Focal mechanisms, aftershocks distribution, and preliminary Sentinel-1 InSAR interferogram suggest that the NW-SE right-lateral strike-slip Pokupsko-Petrinja fault was the source of this ev...
Article
Full-text available
Estimating sound velocity in seabed sediment of shallow near-shore areas submerged after the Last Glacial Maximum is often difficult due to the heterogeneous sedimentary composition resulting from sea-level changes affecting the sedimentary environments. The complex sedimentary architecture and heterogeneity greatly impact lateral and horizontal ve...
Article
Full-text available
We use geophysical and sedimentological data to study the high-resolution acoustic stratigraphy and sedimentology of a Late Quaternary alluvial plain (located in the Gulf of Trieste, northern Adriatic) which was transgressed during the post-LGM sea-level rise. With sub-bottom sonar profiling we determined six acoustic facies, of which the top five...
Article
Full-text available
We use various geophysical datasets (multibeam and singlebeam echosounder data, sub-bottom profiling Chirp and sonar data and very high-resolution boomer seismic data) along with published sedimentological data and depth data from nautical charts in order to create models of the depth of the seafloor and the base of Holocene marine sediment in the...

Article
We use multibeam sonar scanning of the seafloor and high-resolution sub-bottom sonar profiling to investigate pre-Holocene geomorphic features in the Gulf of Trieste that are visible in seafloor topography. We focus on two channel-like features, the Paleorižana and Paleoreka. Sub-bottom profiles and published core log data reveal that these feature...

The youngest seafloor sediments of the Gulf of Trieste (Northern Adriatic) are represented by an up to several 100 meters thick succession of Pliocene to Quaternary continental and shallow-marine deposits recording numerous transgressive-regressive cycles. These sediments are separated from older lithologies (mainly Eocene flysch) by an erosional u...
Poster
Full-text available
In the Gulf of Trieste (northern Adriatic), the seafloor is covered by up to several 100s of m of continental sediments, characterized predominately by alluvial and aeolian deposits that formed during Pleistocene sea-level lowstands. High-resolution multibeam bathymetry revealed the existence of several meandering river channels. One such channel a...
Conference Paper
Full-text available
On November 4-6 2012 heavy precipitation resulted in floods in the middle and lower course of Drava River in NE Slovenia causing damage to many properties in the flooded area. The meteorological situation that led to consequent floods was characterized by high precipitation, fast snowmelt, SW wind and relatively high air temperature. The weather ev...

Project
INQUA projects SPLOSH (https://www.researchgate.net/project/SPLOSH-Submerged-Palaeolandscapes-of-the-Southern-Hemisphere) and Neptune (https://www.researchgate.net/project/NEPTUNE-NEw-Procedures-and-Technologies-for-UNderwater-paleo-landscapE-reconstruction) have come together to host an online workshop, SHINE, on 14 and 15 June 2021. The meeting aims to create a discussion opportunity for researchers dealing with past and recent evolution of coastal and submerged landscapes and provide a non-traditional workshop where participants are invited to present their field activities and study sites as a virtual scientific tour. Presentations can introduce methodologies (or technologies) used during a survey or an ongoing study and we provide an opportunity to showcase research and/or site surveying in its early phases. This meeting format favours ECRs in the early stages of their research projects. We pay particular attention to studies of less known sites, studies conducted with limited funds, demonstrations of innovative technology and/or methodology, and state-of-the-art workflow. The thematic sessions are based on different typologies of coastal landscapes, from past reconstructions to future predictions: •Ancient rocky coasts and their traces along the modern landscape; •Ancient coastal lagoons; •Volcanic coasts and their submerged morphologies; •Urban palaeo-landscapes and anthropogenic traces; •Ancient sandy coasts and their submerged and/or buried morphologies; •Glacial landscapes and their origins; •Wave- or tide-dominated coasts; •Cyclone or tectonically-affected regions. The SHINE motto is “A picture tells a 1000 words”. The deadline for presenting a 300-word abstract, with 1 or 2 photos or figures representing the studied area (template guidelines: https://drive.google.com/file/d/18kTvtdhokcgi4Br6K79_V4tEYoXG3qK8/view), is April 30, 2021.

Project
NEPTUNE INQUA project aims to develop innovative techniques and procedures to analyse the past landscape evolution at a wider scale from near-shore locations to the continental shelf. This project fuels the discussion on this topic by creating a wide community of scientists dealing with all aspects of coastal landscape evolution, such as, for instance, geomorphological, climatic, structural and anthropogenic forcing. Our goal is to create a new scientific network that will discuss the most promising innovative techniques and procedures for submerged landscape reconstructions during workshops and common field activities. Neptune project started its activities online by organizing this first meeting but also by creating our online channels periodically updated with the Neptune news.
