ABSTRACT Stratigraphic and thermochronologic data are used to study the processes that shaped topography of central Apennines Italy. These part a major, active mountain belt in center Mediterranean area, where several subduction zones control complex topography. The were by contraction at front accretionary wedge overlying subducting Adria microplate followed extension rear response eastward sl...

Megathrust faults host the largest earthquakes on Earth, which can trigger cascading hazards such as devastating tsunamis. Determining characteristics that control subduction-zone earthquake and tsunami dynamics is critical to mitigate megathrust but impeded by structural complexity, large spatio-temporal scales scarce or asymmetric instrumental coverage. Here we use high-performance computing ...

Eastern Bangladesh sits on the seismically active Chittagong-Myanmar fold and thrust belt (CMFB), a north-trending accretionary wedge eastern side of India-Eurasia collision. Earthquakes basal décollement associated thrusts within CMFB present hazard to this densely populated region. In study, we interpret 28 seismic reflection profiles from both published unpublished sources constrain depth dé...

introduction wedge modifiers are commonly applied in external beam radiotherapy to change the dose distribution corresponding to the body contour and to obtain a uniform dose distribution within the target volume. since the radiation dose delivered to the target must be within ±5% of the prescribed dose, accurate dose calculation by a treatment planning system (tps) is important. the objective ...

The internal structure of a convergent plate boundary was the focus of ODP Leg 170 in 1996 at the subduction zone off Costa Rica. Although the structure of the subduction zone is rather well known from seismic surveys, prior to drilling of ODP Leg 170 it was a matter of discussion whether it is accretionary or non-accretionary. With a neural network approach, we confirm the evidence gained duri...

Afghanistan sits on the junction between the Indo-Australasian and Eurasian crustal plates and is composed of a series of terranes (Figure 1) that broke away from the main Gondwana supercontinent before colliding with and being accreted on to the Eurasian plate. The accretionary events began in the Cretaceous and have continued until recent times. The Herat or Hari Rod fault, which runs E-W acr...

we describe a simple model that fits well with iranian economy, and extends a methodology which chary at el. (2007) demonstrated. in addition to four traditional wedges, we introduce additional trade wedge. we then evaluate the contribution of these wedges to the fluctuations in iran during last three years. because of international sanction, trading cost increases, and firms have difficulty to...
