Abstract Late Quaternary separation of Britain from mainland Europe is considered to be a consequence spillover large proglacial lake in the Southern North Sea basin. Lake inferred have caused breaching rock ridge at Dover Strait, although this hypothesis remains untested. Here we show that opening Strait involved least two major episodes erosion. Sub-bottom records reveal remarkable set sediment-infilled depressions are deeply incised into bedrock interpret as giant plunge pools. These...
On 1580 April 6 one of the most destructive earthquakes northwestern Europe took place in Dover Strait (Pas de Calais). The epicentre this seismic event, magnitude which is estimated to have been about 6.0, has located offshore continuation North Artois shear zone, a major Variscan tectonic structure that traverses Strait. location and two other moderate historical suggests zone or some its fault segments may be presently active. In order investigate possible activity epicentral area AD...
This paper describes some results of the research undertaken over Brown Bank area during recent (2018/2019) geoarchaeological surveys in North Sea which included seismic imaging, shallow (vibro)coring and dredging. It examines benefits simultaneous high-resolution (0.5 – 1 m) ultra-high-resolution (10–20 cm) survey techniques a staged approach to resolving submerged Holocene landscape highest possible detail for purpose targeted prospecting archaeological material from Mesolithic Doggerland....
The Hazar Basin is a 25 km-long, 7 km-wide and 216 m-deep depression located on the central section of East Anatolian Fault zone (eastern Turkey) predominantly overlain by Lake Hazar. This basin has been described previously as pull-apart because its rhombic shape an apparent fault step-over between main traces situated at southwestern northeastern ends lake. However, detailed structural investigation beneath not undertaken to verify this interpretation. Geophysical sedimentological data...
Abstract Deltas contain sedimentary records that are not only indicative of water‐level changes, but also particularly sensitive to earthquake shaking typically resulting in soft‐sediment‐deformation structures. The Kürk lacustrine delta lies at the south‐western extremity Lake Hazar eastern Turkey and is adjacent seismogenic East Anatolian Fault, which has generated earthquakes magnitude 7. This study re‐evaluates changes have affected Delta, combining geophysical data (seismic‐reflection...
The North Anatolian Fault is a ca. 1200-km-long, right-lateral, strike-slip fault that forms the northern boundary of plate. A damaging sequence earthquakes ruptured almost entire in twentieth century. This study adds to growing number paleoseismic investigations 350-km-long 1939 Erzincan earthquake-rupture segment, which towards eastern end Turkey. Using three trenches located along 2 km principal strand, this determines timing five prior earthquake. first these are correlated historical...
Abstract. On 8 November 1983 an earthquake of magnitude 4.6 damaged more than 16 000 buildings in the region Liège (Belgium). The extraordinary damage produced by this earthquake, considering its moderate magnitude, is extremely well documented, giving opportunity to compare consequences a recent typical old city Western Europe with scenarios obtained combining strong ground motions and vulnerability modelling. present study compares 0.3 s spectral accelerations estimated from motion...
