Final report

 
Results in Hungarian
A projekt célja egy regionális tektonikai sebességtérkép készítése volt melynek során integráltuk a hosszabb idő óta Magyarországon, valamint Közép-Európában nemzetközi együttműködésben folytatott GPS geodinamikai vizsgálatok eredményeit. Korábban 1991-ben illetve 1994-ben létrehozták a szélső pontosságú GPS mérésekre alkalmas magyar, valamint közép-európai geodinamikai alappont-hálózatokat (HGRN,CEGRN). A projekt támogatásával ezeken a hálózatokon további nagy precizitású GPS mérések történtek 2003-ban és 2005-ben. Feldolgozásuk a szélső pontosságú BERNESE hálózati tudományos szoftverrel történt. A kiértékelés a korábban kapott eredményekre is megtörtént, ezáltal immár 14 illetve 11 éves méréssorokhoz jutottunk. A mérési pontosság horizontálisan 1,5 mm-nek vertikálisan 4,5 mm-nek adódott. Az alkalmazott légköri modellek és feldolgozási módszerek javításával sikerült a vertikális komponensek pontosságát javítani. A GPS mérési sorozatok kiértékelése eredményeképpen a projekt során egyre megbízhatóbb HGRN és CEGRN sebességvektorokhoz jutottunk egy „kontinensen belüli - intraplate” vonatkozási rendszerben. A horizontális sebességvektorok hibája átlagosan kisebb, mint 1 mm/év. Ezáltal sikerült a pontok által lefedett terület tektonikai sebességviszonyait minden eddigit meghaladó pontossággal feltérképezni. Ezzel nem csak számos korábbi földtudományi hipotézist sikerült alátámasztanunk, vagy pontosítanunk, hanem több új és meglepő következtetésre is jutottunk.
Results in English
The main objective of the project was to construct a regional tectonic velocity map by reprocessing the earlier GPS geodynamic monitoring data in Hungary as well as in the Central European region. In 1991 the Hungarian GPS reference network (HGRN) and in 1994 the Central European reference network (CEGRN) were established and monitored for geodynamic investigations. With the support of the project two additional monitoring measurement campaigns were carried out in 2003 and in 2005. The data processing was completed with the BERNESE software package. The processing and the analysis took also the earlier measurements into consideration, consequently 14 years; respectively 11 years time series were obtained on these networks. The horizontal accuracy achieved was better than 1.5 mm and the vertical accuracy was better than 4.5 mm for the whole network area. Due to the improved atmospheric models and processing methods, the vertical accuracy could also be improved. The longer time base led to more accurate velocity vectors of the HGRN and CEGRN sites. Consequently we were able to construct a highly reliable intraplate velocity map of the region. The horizontal accuracy of the vectors is better than 1 mm/yr. The investigations provided some surprising new results and supported some earlier assumptions concerning the tectonic activities in our region.
