nto the world's deep seas and oceans. These events are difficult to predict, are destructive, and take place in the most inhospitable part of our planet (the deep marine), so we still know very little about them. In the past 40 years, researchers have assumed these flows are somewhat similar to rivers, but Joris T. Eggenhuisen Utrecht University and William D. McCaffrey of the University of Leeds present experiments that show that a critical assumption about the pressure in river flow cannot be applied to submarine currents. This changes our view of how sediment avalanches build submarine channels and slopes, and necessitates a revision of widespread modeling approaches.


How tough is tuff in the event of fire?
M.J. Heap et al., Laboratoire de Gophysique Exprimentale, Institut de Physique de Globe de Strasbourg (UMR 7516 Centre National de la Recherche Scientifi que, Universit de Strasbourg/Ecole et Observatoire des Sciences de la Terre), 5 rue Ren Descartes, 67084 Strasbourg cedex, France. Posted online 2 Mar. 2012; doi: 10.1130/G32940.1.

Tuff has been extensively used as a building material in volcanically and tectonically active areas over many centuries, despite its inherent low strength. A common and unfortunate secondary hazard accompanying both major volcanic eruptions and tectonic earthquakes is the initiation of catastrophic fires. Here, M.J. Heap of the Institut de Physique de Globe de Strasbourg and colleagues report new experimental results on the influence of high temperatures on the strength of three tuffs that are commonly used for building in the Neapolitan region of Italy. Their results show that a reduction in strength was only observed for one tuff; the other two were unaffected by high temperatures. The cause of this strength discrepancy was found to be a product of the initial mineralogical composition, or, more specifically, the presence of thermally unstable zeolites within the initial rock matrix.
