-
(2006)The Iberian Peninsula and the Maghreb experience moderate earthquake activity and oblique, ~ NW-SE convergence between Africa and Eurasia at a rate of ~ 5 mm/yr. Coeval extension in the Alboran Basin and a N35°E trending ...
-
(2006)The October 2005 series of earthquakes that occurred in the Gulf of Siǧaçik (western Turkey) reveal the operation of pure strike-slip faults, as evidenced from the 49 focal mechanisms we determined, in a region dominated ...
-
(2006)Deformation models used to explain the triggering mechanism often assume pure elastic behaviour for the crust and upper mantle. In reality however, the mantle and possibly the lower crust behave viscoelastically, particularly ...
-
(2006)The northern part of the Dead Sea Fault Zone is one of the major active neotectonic structures of Turkey. The main trace of the fault zone (called Hacıpaşa fault) is mapped in detail in Turkey on the basis of morphological ...
-
(2006)On 8 January 2006 at 11:34 GMT (13:34 local time), a strong earthquake with a moment magnitude of 6.7 occurred in southern Greece, off the eastern coast of the island of Kythira. The epicentral coordinates as estimated by ...
-
(2006)Spatio-temporal clustering of microseismicity in the central forearc of the Hellenic Subduction Zone in the area of Crete is investigated. Data for this study were gathered by temporary short period networks which were ...
-
(2006)Seismotectonic parameters including the Gutenberg-Richter b-value and multifractal dimensions D2 and D15 of seismicity patterns (both spatial and temporal) were compared to GPS-derived maximum shear and dilatation strains ...
-
(2006)The volcanic arc of the Hellenic subduction zone with its four volcanic centers is of major relevance when evaluating the seismovolcanic hazard for the Aegean region. We present results from a 22-station temporary seismic ...
-
(2006)Comparison between the tectonic and palaeogeographic evolution of the Mediterranean region from the Oligocene to the Present shows that the isolation of the Mediterranean region is a progressive process that started some ...
-
(2006)GPS results from 25 stations in Macedonia measured in 1996 and 2000 show that Macedonia moves SSE relative to Eurasia essentially as a single crustal piece along with parts of westernmost Bulgaria. Geological studies show ...
-
(2006)Since the early 1990s, a prolific literature has developed on the interpretation within western Turkey of apparent Mid to Late Cenozoic low-angle normal faults. Extension on these structures has been thought responsible ...
-
(2006)Gravitational potential stresses (GPSt) are known to play a first-order role in the state of stress of the Earth's lithosphere. Previous studies focussed mainly on crust elevation and structure and little attention has ...
-
(2006)We report new palaeomagnetic results from a ca. 1300 to 800Ma continental shelf succession on the southern margin of the North China Block. A total of 386 oriented core samples were subjected to stepwise demagnetisation. ...
-
(2006)The molecular composition of water-soluble products generated by the natural degradation of charcoal particles over a period of 100 years in a temperate forest soil has been investigated by ultrahigh resolution mass ...
-
(2006)Relatively little information is available in the literature regarding the speciation and solubility of Ga, Ge, In and Sc in aqueous solutions, especially at elevated temperatures and pressures. In this paper we critically ...
-
(2006)Massive scleractinian corals secrete an aragonitic skeleton which incorporates a large array of chemical tracers. Corals present several advantages for palaeoclimate research: they grow continuously, and can live up to ...
-
(2006)The crystallography and geometry of high-angle grain boundaries from dynamically recrystallized quartz have been studied. On the basis of combined electron backscatter diffraction and universal stage measurements, the ...
-
(2006)The taxonomy and biostratigraphy of the Aeronian graptoloid graptolites of the Tanezzuft Formation (Murzuq Basin and Al Qarqaf Arch area) is presented and discussed with respect to their palaeoenvironmental setting and ...
-
(2006)Occurrences of fossil lungfishes (Dipnoi: Sarcopterygii) in the Famennian Catskill Formation of Pennsylvania are reviewed. A nearly complete dermal skull roof is assigned to a new genus and species, Apatorhynchus opistheretmus. ...
-
(2006)The surface of the Moon is a critical boundary that shapes our understanding of the Moon as a whole. All geologic mapping and remote sensing techniques utilize only the outermost portion of the Moon. Before leaving the ...
