Continental arcs have an episodic magmatic activity over long-time periods, which is believed to modulate long-term climate. Island also the potential release large amount of CO 2 into atmosphere, but whether they display history throughout their lifespan that contributes (>10 Ma) climate changes remains open question. To set additional constraints on island arcs, here we examine fresh b...

We discussed the peculiarities of seismic cycle in Aleutian subduction zone, characterized by an oblique setting. It was shown that orientation plate convergence vector relative to zone axis can have a significant impact on preparation and occurrence largest earthquakes zones. In particular, from analysis activity occurring western part island arc, it found cycles here are shorter than eastern ...
