The aim of this paper is to conceptualize and design a risk topography that outlines a data acquisition and dissemination process that informs policy markers, researchers and market participants about systemic risk. Our approach emphasizes that systemic risk (i) typically builds up in the background before materializing in a crisis and (ii) is determined by market participants’ response to vari...

Gibbs oscillations in the truncated spectral representation of the earth's topography are strongly reduced by determining its spectral coefficients as a minimum of a nonuniformly weighted, nonquadratic cost function. The cost function penalizes the difference between spectral and true topography with weights that are explicit functions of the topographic height and its gradient. The sensitivity...

Precise factors controlling the coevolution of deformation and topography in tectonically active landscapes remain poorly understood due to complex feedbacks between numerous possible variables. Here we examine the links between fault kinematics, emergent topography, and environmental factors on a global data set of active fault-driven mountain ranges (n = 41). Using simple regressions between ...

The long-wavelength geoid and topography are dynamic effects of a convecting mantle. The long-wavelength geoid of the Earth is controlled by density variations in the mantle and has been explained by circulation models involving whole mantle flow. However, the relationship of long-wavelength topography to mantle circulation has been a puzzling problem in geodynamics. We show that the dynamic to...

Article history: Received 12 January 2016 Received in revised form 26 May 2016 Accepted 27 May 2016 Available online 31 May 2016 A fundamental scientific question is, what controls the Earth's topography? Although the theoretical principles of isostasy, flexure, and dynamic topography arewidely discussed, the parameters needed to apply these principles are frequently not available. Isostatic fa...

We use the landcape evolution model Zscape to explore quantitatively the development of mountainous topography in the Basin and Range province (formerly the Basin Ranges), USA, as a function of faulting, surface processes and microclimate. Many of the classic morphologies of mountains in the Basin and Range were described in the late part of the 19th century. The varied topography coupled with ...

In this article a topographical description of the Cueva Mayor Cueva de Silo cave system is provided, including a more detailed topography of the Sala de los Ciclopes Sala de las Oseras-Sima de los Huesos sector. The history of the excavations and discoveries of human and carnivore fossils in Sima de los Huesos and adjacent passages is briefly reported, as well as the increase, throughout the s...

The quantification of surface structure is of major importance for several industry sectors. For the paper industry, the surface topography is essentially important for securing a good print quality of various paper grades. The surface affects various print quality parameters such as ink transfer, ink distribution, gloss and missing dots. It is thus important to have a detailed assessment of su...
