Two end-members characterize a continuum of continental extensional tectonism: rift settings and highly extended terrains. These different styles result in and are recorded by different extensional basins. Intracontinental rifts (e.g. East Africa, Lake Baikal) usually occur in thermally equilibrated crust of normal thickness. Rift settings commonly display alkali to tholeiitic magmatism, steepl...

Abstract Landforms and sediments on the palaeo–ice stream beds of central Alberta record glacitectonic raft production subsequent progressive disaggregation moulding, associated substrate ploughing, grooving. We identify a subglacial temporal or developmental hierarchy that begins with incipient rafts, including en échelon hill-hole complexes, pairs, strike-slip all which display patterns typic...

In complex domains such as scientiic computing, users need support in choosing, chaining, and executing the adequate programs for problem solving. Problem solving environments are developed in order to solve automatically routine problems, decomposing them recursively in more and more elementary subproblems, and nally executing the corresponding programs. But often, the problem solving process ...

[1] Pedestal craters on Mars are defined by an outwardfacing scarp forming a plateau perched tens of meters above the surrounding terrain. Their origin has been attributed to impact armoring of the surface and subsequent removal of inter-crater terrain by either eolian deflation or sublimation of an ice-rich substrate. We identified 2696 pedestal craters between 60 N and 60 S latitude; 98% are ...

[1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record failures that mobilized along extensional failure planes and transformed into long runout flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment causing extensional failure that drove successive scarp formation updip. This model is developed from three-dimensional seismic reflect...

We apply a deep learning model to segment and identify rock characteristics based on Structure-from-Motion orthomap digital elevation of rocky fault scarp in the Volcanic Tablelands, Eastern California, USA. By post-processing results, we build semantic map analyse trait distributions. The resulting contains nearly 230 000 rocks with effective diameters ranging from 2 250 cm. Rock distributions...

Wireless sensor networks sense various kinds of information, process them locally and communicate it to the outside world via satellite or Internet. In the near future, sensor networks will play a major role in collecting and disseminating information from the fields where ordinary networks are unreachable for various environmental and strategical reasons. Hence it is increasingly likely that s...

This paper explored the relationship between acidic sulfate alteration, geostructural frameworks, and geomorphological changes that can be observed in active volcanic hydrothermal systems. The target area was Pisciarelli Campi Flegrei volcano, where diffuse alteration dynamics have been growing since 2012, causing a progressive deterioration of landscapes. Terrestrial Laser Scanner (TLS), photo...

While the cyclic nature of tectonic strain build-up and release is at least conceptually well understood (known as earthquake cycle), it not clear how variable corresponding sizes time intervals between them are. Additional observations from past earthquakes are required to better constrain these aspects. In this context, we investigate roughness bedrock normal fault scarps along Mt. Vettore Ro...
