New paper: Why geomorphic indices often fail in active tectonics studies

Geomorphic indices can tell us about the tectonic activity of an area. The idea is that the landscape records the signal of active tectonics, for example in its river network, in its erosion pattern, or in its roughness. Geomorphic indices allow us to quantify this, that is, we can use standard algorithms to calculate numbers from a DEM that say ‘active’ or ‘inactive’. This is very attractive because essentially, all that is needed is a DEM and a GIS

Al parecer veía un cierto consenso en cuanto a no emplumarlos. Y bueno, me dije, vamos a intentar explicar bien este tema, porque tiene mucha miga.Si es que te gustan los dinosaurios, claro. Si no es así, puedes dejar de leer aquí y echar a

 That's a long flight from Tahiti.  I thought I was smart and overdosed on gravol.  Don't do that!  I got the heeby-jeebies and palsy for my computer finger.  Hope it clears up.Looking from the plane I [...]

 This is fun.  The Antarctic temp has remained flat as a board.  The ice either expands, then it is 'mindblowing' ice loss, or it shrinks at mindblowing lows.  No pleasing
