Aligned buoyant highs, across-trench deformation, clustered volcanoes, and deep earthquakes are not aligned with plate-tectonic theory

Bathymetry shows the regional interaction of aseismic, buoyant highs in northern Pacific subduction zones. Seamonts, ridges, and fractures on the seaward side of the trench are associated with events that do not support the accepted plate-tectonics
paradigm, including an altered slab dip angle (Benioff zone) and the clustered volcanoes and earthquakes within the convergent margin. That data will then be used to formulate a new theory, into the realm of the surge-tectonic hypothesis, that encompasses
The evolution of the Molopo drainage can be explained both in terms of tectonics and climatic variations. The present Molopo has no record of any permanent flow during living memory and has acquired all the characteristics of a fossile drainage

A morphometric comparison of valleys has been made for the Ben Ohau Range in the central Southern Alps of New Zealand. The range is undergoing rapid tectonic transport and uplift. First, the sequence of topographic transitions caused by a change
in dominant process regime, from fluvial to glacial erosion, is described. Then, the time-scale of change is evaluated. Finally, observations are related to the hypothesized relief development implicit in existing tectonic-isostatic models of alpine uplift.

and stream gradients) show that little or no uplift occured in the second half of the Cenozoic. Tectonics capable of raising the range occured in the Mesozoic era, most recently in the late Cretaceous. Uplift histories of other ranges need re-evaluation
The eruptive history of the Tihany Peninsula (Lake Balaton, Hungary) has been studied in detail to understand the evolution of volcanic and tectonic structures. Tectonic and depositional features indicate a maar-type origin of the Outer Lake
The relationship between pluvial fan and terrace morphology and differential tectonic movement along the North Qinling fault zone, Shaanxi Province, China
Biostratigraphical and sedimentological studies of deposits of terraces on Western Sakhalin Island have shown that they were all marine in origin. The upper complex of terraces formed during a period of slow tectonic uplift in this area to 120 m
above modern sea level. The lower complex of terraces may have formed in response to sea level oscillations without any influence of tectonic uplift.
The location of Poland at the junction of three main tectonic units of Europe created a possibility of great diversity of fluvial systems. Under the climatic fluctuation an important role was played by the drainage towards the north and by blocking
in extraglacial mountain valleys with changeable flood frequencies and tectonic tendencies. In the middle parts there is a distinct phase of continental climate. In the zone of last glaciation ice marginal streamways were developed in association with superimposed
The geologic and biologic diversity, multiphase tectonics and special geomorphologic phenomena formed the Protected Landscape Region Železné hory (Ferrons Mts.). Changes of river and valley network, attractive local relief and geoenvironmental
