In the last few decades dense large-scale seismic networks showed their importance in studying structure of lithosphere and upper mantle. The better understanding Apennines–Alps–Carpathian–Dinarides system is main target AlpArray European international initiative which more than 50 institutes are involved. core Seismic Network (AASN). With its $$\sim $$ 600 broadband stations ( 280 temporary) AASN is, so far, largest passive experiment Europe. MTA CSFK Geodetic Geophysical Institute, as a...
With the discovery of József-hegy Cave, a cave hydrothermal origin with an abundance minerals unknown so far in Hungary came to light. Diversity and frequency occurrence crystals make this similar Lechuguilla even if dimensions mineral precipitations passages do not compare scale. The variety mass carbonates sulphates are surprising. This paper describes speleothems their genesis, including determined ages. 41 U/Th measurements suggest that begun develop upper level more than 350 ka ago....
Summary We take advantage of the new large AlpArray Seismic Network (AASN) as part research initiative (www.alparray.ethz.ch), to establish a consistent seismicity-catalogue for greater Alpine region (GAR) time period 2016 January 1–2019 December 31. use data from 1103 stations including AASN backbone composed 352 permanent and 276 (including 30 OBS) temporary broad-band (network code Z3). Although characterized by moderate seismic hazard, European Alps surrounding regions have higher risk...
Information on seismic anisotropy in the Earth's mantle can be obtained from (1) shear-wave splitting analyses which allow to distinguish single or multi-layered and delay time of fast slow polarized wave indicate its thickness, (2) studying peridotites where properties inferred lattice preferred orientation deformed minerals. We provide a detailed map western part Carpathian-Pannonian region (CPR), an extensional basin recently experiencing tectonic inversion, using data. then compare...
The aim of this study was to establish a 3D shear-wave velocity model the transition zone between Eastern Alps and Pannonian basin by means ambient noise tomography. Datasets from permanent networks as well past recently deployed temporary broadband seismic stations have been processed. Empirical Green's functions were estimated via cross-correlation vertical component further processed obtain Rayleigh-wave group-velocity dispersion curves. They directly inverted for shear velocities through...

<div>A magnitude ML 4.0 earthquake struck southwest Hungary on March 7, 2019. The was reported to be felt in some 53 localities with maximum intensity V the EMS scale. preceded by four foreshocks and followed by aftershocks. hypoDD solutions using differential travel times from waveform cross-correlation show significant improvements event location. We were able determine moment tensor for main shock one of aftershocks, each...

Earthquakes are one of the most devastating natural disasters on Earth, causing sometimes huge economic losses and many human casualties. Since earthquake prediction is not yet possible, purpose civil protection to reduce damage protect lives, in which seismological networks different countries play a very important role. Special applications seismic early warning systems that can be used vulnerable infrastructures using automated shutdown procedures, stop high velocity trains save lives if...
