“…Thrusts as well as segments of the Tóalmás zone were reactivated during this event. This is corroborated by doming of the Upper Pannonian at Tóalmás, as already observed by Fodor et al (2005a) and Ruszkiczay-Rüdiger et al (2007). As no detailed sedimentological mapping for the Pannonian has been undertaken, the absolute age of this phase remaines to be solved.…”

“…1), this is a valid name in the western part of the country. In a neotectonic study of the region (Fodor et al 2005a), partly overlapping with the current study area, the eastern continuation of the Balaton line has been called the Tóalmás line (or zone). As we deny the direct continuity of the strike-slip system to the west (a separate study focusing on this issue is in preparation), this latter name will be used in the following.…”

Abstract:Recently shot 3D seismic data allowed for a detailed interpretation, aimed at the tectonic evolution of the central part of the Mid-Hungarian Shear Zone (MHZ). The MHZ acted as a NW vergent fold and thrust belt in the Late Oligocene. The intensity of shortening increased westwards, causing clockwise rotation of the western regions, relatively to the mildly deformed eastern areas. Blind thrusting and related folding in the MHZ continued in the Early Miocene. Thrusting and gentle folding in the MHZ partly continued in the earliest Pannonian, and was followed by sinistral movements in the whole MHZ, with maximal displacement along the Tóalmás zone. Late Pannonian inversion activated thrusts and generated transpressional movements along the Tóalmás zone.

“…Horváth and Royden (1981) pointed out the occurrence of thinning and updoming of the lithospheric mantle, thermal contraction and related subsidence in a post-rift phase of basin formation. In general, uplift, denudation and sedimentation are competing processes in the Transdanubian zone and all need to be considered to understand the neotectonic pattern of this part of Central European (Fodor et al, 2005). Convergence with the Nubia plate is mirrored by seismic activity at considerable depth (>100 km) in the Vrancea Seismic Zone, and to some extent by the kinematics of the Adria microplate and the Pannonian Basin.…”

The Central European Geodynamics Project CERGOP-2, funded by the European Union from 2003 to 2006 under the 5th Framework Programme, benefited from repeated measurements of the coordinates of epoch and permanent GPS stations of the Central European GPS Reference Network (CEGRN), starting in 1994. Here we report on the results of the systematic processing of available data up to 2005. The analysis has yielded velocities for some 60 sites, covering a variety of Central European tectonic provinces, from the Adria Indenter to the Tauern Window, the Dinarides, the Pannonian Basin, the Vrancea Seismic Zone and the Carpathian Mountains. The estimated velocities define kinematical patterns which outline, with varying spatial resolution depending on the station density and history, the present-day surface kinematics in Central Europe. Horizontal velocities are analyzed after removal from the ITRF2000 estimated velocities of a rigid rotation accounting for the mean motion of Europe: a ∼2.3 mm/year north-south oriented convergence rate between Adria and the Southern Alps that can be considered to be the present-day velocity of the Adria Indenter relative to the European Foreland. An eastward extrusion zone initiates at the Tauern Window. The lateral eastward flow towards the Pannonian Basin exhibits a gentle gradient from 1 to 1.5 mm/year immediately east of the Tauern Window to zero in the Pannonian Basin. This kinematic continuity implies that the Pannonian plate fragment recently suggested by seismic data does not require a specific Eulerian pole. On the southeastern boundary of the Adria microplate, we report a velocity drop from 4 to 4.5 mm/year motion near Matera to ∼1 mm/year north of the Dinarides, in the southwestern part of the Pannonian Basin. A positive velocity gradient as one moves south from West Ukraine across Rumania and Bulgaria is estimated to be 2 mm/year on a scale of 600-800 km, as if the crust were dragged by the counterclockwise rotation along

“…According to Fodor et al (2005), based on structural analysis, earthquake and GPS data, the south-eastern Pannonian-Carpathian (Tisza) unit is currently moving eastward with respect to the north-eastern block of the ALCAPA unit and this process results in the formation of active transtensional and transpressional shear zones in the region of the Mid-Hungarian line.…”

Macroseismic intensity data of the 22 April 2013 Tenk (Hungary) earthquake

2014

On 22 April 2013 an earthquake of magnitude 4.8 occurred near the village of Tenk (Hungary), which was the strongest Hungarian earthquake in the past 28 years. This event was detected by a number of seismological stations, thus it is well documented. Nevertheless, it is still possible to get further data through macroseismic surveys, which cannot be obtained using seismological instruments, but are very useful for the understanding of seismic properties of the affected area.The studied earthquake was felt in approximately third of the territory of Hungary. The number of incoming macroseismic questionnaires was over eight hundred and damage descriptions for the epicentral area reached almost one thousand. Intensity evaluation was carried out following the European Macroseismic Scale guidelines (Grünthal et al, 1998). Intensities were assigned to 211 places, including 23 districts of Budapest. The earthquake caused non-structural building damages, the epicentral intensity was estimated as VI on the EMS-98 scale and was assigned to three villages: Tenk,Átány and Erdőtelek. The event was widely felt west to the epicentre, but much less observed in the east direction. The asymmetry of the intensity distribution raises questions and requires further investigation.
