Subduction zones are areas of frequent earthquakes and are usually associated with the rows of volcanic islands that accompany the oceanic trenches. Subduction is currently happening beneath island arcs, like Japan. Subduction is also taking place on the Pacific Northwest Coast of North America, ...
Giant earthquakes (Mw≥8.5) usually occur on the boundary between subducting and overriding plates of converging margins, but it is not yet clear which (if any) subduction zones are more prone to produce such a kind of events. Here we show that subduction zones may have different capabilities...
Among others, kimberlite magmatism has been correlated with lithospheric flexures, regional uplifts above upwelling convection currents (mantle diapirs, mantle hot spots), rifting of continents, flat-dipping subduction zones, non-laminar flow above subduction zones, transform faults, and magneto-...
One of the things that began to contribute to further reductions in CO2 were not just the weathering of rocks, but now marine organisms that incorporated calcium carbonate into their shells. These organisms then died and were swept under the crust at subduction zones. The asteroid was really jus...
It is of interest to note that of the three occur- rences falling within unfavorable zones, two are within 1.5 km to a nearest favorable zone. Thus, seven of the eight (or 87.5%) porphyry copper occurrences not Where are Porphyry Copper Deposits Spatially Localized? 57 Table 5. Summary of...

I try to find an indicator to differentiate the subduction zones where Mw9 earthquakes occur. Stress drops in Mw9 zones are significantly high. I derive the scaling relations, which take into account the variation of . It is derived that Mo should be normalized by 1.5 in the scaling ...
