Field observation combined with remote sensing, employing both Landsat images and aerial photographs, and the analysis of topographic, geomorphological and geological maps show that the regional contrasts in seismicity and associated tectonic
Low-temperature thermochronology, such as that provided by apatite fission-track analysis, provides a valuable means of establishing the timing of major denudational events and associated rates of denudation over geological time-scales of 106-108 Ma
