Temporal characteristics of some aftershock sequences in Bulgaria
Aftershock Aftershock decay rate secondary Aftershock sequences
2015/9/30
We apply statistical analysis to study the temporal distribution of aftershocks in aftershock sequences of five earthquakes which occurred in Bulgaria. We use the maximum likelihood method to estimate...
The Kresna earthquake in 1904 in Bulgaria is one of the largest shallow 20th century events on land in the Balkans. This event, which was preceded by a large foreshock, has hitherto been assigned a ra...
State-of-the-art of historical earthquake investigation in Bulgaria
macroseismology bulletins and catalogues supporting data set site seismic histories
2015/9/14
This paper deals with non-instrumental seismology development in Bulgaria (the central-eastern part of the Balkan peninsula). The first steps and products of this scientific branch are discussed becau...
Abstract. We use a coupled atmosphere- re model to simulate a re that occurred on August 14{17, 2009, in the Harmanli region, Bulgaria.Data was obtained from GIS and satellites imagery, and from stan...
The Silistar Intrusive, Eastern Srednogorie Zone, Bulgaria: Structural Data and Potential for Porphyry Copper and Epithermal Systems
Eastern Srednogorie Bulgaria Silistar intrusion porphyry copper epithermal
2009/7/8
The Late Cretaceous Silistar intrusion comprises of gabbros, gabbro-diorites to quartz-diorites and aplites, that were emplaced into a volcano-sedimentary succession of similar age. Structural data su...
Alpine Metamorphism and Granitoid Magmatism in the Strandja Zone: New Data from the Sakar Unit, SE Bulgaria
Strandja zone Sakar unit Alpine tectonics syntectonic granitoids structural geology
2009/7/7
The Strandja Zone is a pre-Cenomanian orogen consisting of three tectonic units: the Veleka, Strandja and Sakar units. The first two units display very low-grade Alpine metamorphism, whereas in the S...
Modelling the water budget and the riverflows of the Maritsa basin in Bulgaria
water budget Maritsa basin soil-vegetation-atmosphere
2009/4/28
A soil-vegetation-atmosphere transfer model coupled with a macroscale distributed hydrological model was used to simulate the water cycle for a large region in Bulgaria. To do so, an atmospheric forci...
Probabilistic seismic hazard in terms of intensities for Bulgaria and Romania–updated hazard maps
Probabilistic seismic hazard terms of intensities Bulgaria Romania updated hazard maps
2010/1/4
Since 2007 Bulgaria and Romania are members of the European Union. All member states have to introduce the European earthquake building code EUROCODE 8 (EC 8) in the coming years. Therefore, new seism...
