“…Mackey et al (1997) have recently de"ned the Bering Sea, Chukotka Peninsula, Seward Peninsula and part of western Alaska as an independent tectonic block that has been rotated clockwise in tandem with the northwest subduction of the Paci"c plate. Rotation of the Bering Block is thought to have been initiated 5.5 My ago providing a realistic mechanism for the initial extension, faulting and submergence of the Bering Strait region.…”

Aspects of the paleogeography, stratigraphy, and glacial history of Beringia have been greatly revised over the past 15}20 yr. Access to North East Russia, in particular, has provided the opportunity to evaluate the Beringia landscape as a contiguous subcontinent during the Quaternary. For the "rst time, new research has made clearer the connection between tectonic forces and the submergence of the Bering Strait during the middle Pliocene. Revisions in the regional stratigraphy of glacial and interglacial deposits in northwest Alaska and northeast Russia provide a new foundation for assessing the causes for di!erences in glacial ice extent through time. The consensus of all "eld workers veri"es that glacial ice throughout most of Beringia was of very limited extent during the last glacial maximum. The onset of regional glaciation during the waning stages of the last interglaciation is clearly out of phase with glaciation at lower latitudes. Despite the lack of much glacial activity during the early Holocene, Alaska contains a rich record of late Holocene glacial response to Neoglacial cooling. Changes in the Holocene environment of Beringia likely had a profound a!ect on early inhabitants. The curiosity-driven vision and spirit of both David Hopkins and the late Troy Pewe have had a profound in#uence on Arctic paleoenvironmental research.

Abstract:Based on the analysis of changes in the stress-strain state of the crust at the boundary of the Eurasian and North American tectonic plates, we develop a dynamic model of the main seismogenerating structures in Northeast Asia. We have established a regularity in changes of geodynamic regimes within the interplate boundary between the Kolyma-Chukotka crustal plate and the Eurasian, North American and Pacific tectonic plates: spreading in the Gakkel Ridge area; rifting in the Laptev Sea shelf; a mixture of tectonic stress types in the Kharaulakh segment; transpression in the Chersky seismotectonic zone, in the segment from the Komandor to the Aleutian Islands, and in the Koryak segment; and crustal stretching in the Chukotka segment.

“…There were some papers that inspired to search scientific explanations about the Cuban seismicity as (Makarov and Schukin, 1976;) Sibson, 1985;Spiridonov and Grigorova, 1980). The results of (Assinovskaya and Soloviev, 1994;Backmanov and Rasskazov, 2000;Guelfand et al, 1976;Gvshiani et al, 1987;Mackey et al, 1977;Sherman and San`kov, 2010;Stein and Yeats, 1989;Zhidkov, 1985;Zhidkov et al, 1975) contributed to develop the methodology of the active structures. In order to obtain the comprehension of the earthquakes localization on intraplate zones were used (Campbell, 1978;Jonston, 1989;Johnston and Kanter, 1990;Leonov, 1995;LeRoy and Mauffret, 1996;Liu and Zoback, 1977;Sbar and Sykes, 1973;Stein, 1999;Sykes, 1978;Zoback, 1992).…”
