NORTHERN EURASIA The JIPE of Moscow is coordinating the seismic hazard mapping for the whole FSU territory.
The preliminary PGA map includes the contributions of Ibero-Maghreb, Adria, Central-Northern Europe, Northern Eurasia, Caucasus, Greece, Turkey and Circum Pannonian and is accompanied by a compilation of the individual source zones (see figures).
The inferred depth was about 5 km and the focal mechanism by several agencies indicated a thrust type faulting with the P axis trending NNE, consistent with the direction of the India-Eurasia plate motion.

 Eurasia Basin
In spite of the well established first-order view of the Eurasia Basin, much of the detail of the structure and evolution of this ocean and its margins remains enigmatic due to the permanent ice cover of most of the region.
The new data cover a 1,200,000 km**2 region between the Eurasia margin and the Canada Basin/Fletcher Abyssal Plain with a typical line spacing of 18 km.
We speculate that the initial rifting of the Lomonosov Ridge may have occurred in a back-arc basin environment or alternatively, an older ocean basin may have existed between some portion of the Lomonosov Ridge and the Eurasia margin prior to rifting and connection with the North Atlantic.

 EurasiaNet Eurasia Insight - Those Playing Caspian Basin Energy Game May Suffer from “Irrational Exuberance” -- Expert
The Caspian Basin is now the scene of intense competition among the United States, Russia and China, which are all battling for control over natural resources and export routes.
He also noted that in Kazakhstan a middle class is rapidly developing, and poverty is falling as a result of oil and gas revenues.
The Central Eurasia Project aims, through its website, meetings, papers, and grants, to foster a more informed debate about the social, political and economic developments of the Caucasus and Central Asia.

Above is a diagram of the general large scale water circulation in the Arctic Ocean, along with some of the major topographic features of the ocean bottom.
The basin of the Arctic Ocean is crossed by several prominent ridges which restrict the circulation of the bottom water and divide the Arctic basin into several sub-basins (Amerasia basin, Eurasia basin, and the Barents Sea).
In the Eurasian basin the Arctic bottom water (at 2500 meters depth) reaches a temperature of about -0.8 degrees C., while in the Amerasia basin it reaches (at 2000 meters depth) approximately -0.4 degrees Centigrade.

 Eurasia Policy Forum
The resource-rich states of the Caspian Basin today face the very real prospect of unprecedented revenues from the sale and transport of oil and natural gas, and from mining.
The Central Eurasia Project, a program of the Open Society Institute (Soros Foundations), sees the transparent use of revenues generated by the sale and transport of Caspian natural resources as an issue of great importance for regional development and the promotion of civil society.
The Eurasia Policy Forum identifies and addresses emerging policy issues that have an impact on the development of open societies in the south Caucasus and Central Asia region.

 NE Russia Workshop
It transitions from the ultra-slow spreading Gakkel (Arctic) mid-ocean ridge in the Eurasia Basin of the Arctic Ocean, across a diffuse zone of extension in the continental crust of the Laptev Sea, into diffuse, presumed to be transpressional, zones in the Verkhoyansk and Chersky Ranges of northeast Asia which extend to Kamchatka and Sakhalin.
The “Moma rift” was previously thought to be the continuation of Arctic extension (e.g., Grachev, 1982), however, these basins appear to be either inactive or under compression (Imaev et al., 2000) in the present time.
The interactions of these regions are important for a number of reasons including the determining history of oceanic connections between these two ocean basins, the tectonic evolution of Alaska, the nature of the circum-Pacific margins over time, and the plate motions of both North America and Eurasia.

 Iceland: An Outcome of Plate Tectonics
Vink (1984) recognized the paradox of explaining the development of the GFR in a fixed hot spot framework, and proposed a model whereby asthenosphere was channelled the shortest distance from a presumed plume centre under Greenland to the nearby Reykjanes Ridge.
The hinge zone probably acted as a barrier to further propagation and triggered plate reorganization, analogous to the manner the Neo-Tethyan hinge zone hindered further propagation of the Red Sea – Gulf of Suez rift (Steckler and ten Brink, 1986).
However, we show from plate tectonic considerations that opening of the NE Atlantic and Arctic Eurasia can be explained as a natural consequence lithospheric strength control on final breakup of Pangea, and need not appeal to lithospheric weaking by a plume.
