Digitally Enhanced Maps and Sections
William Smith has often been declared to be the ‘Father of English Stratigraphy’. Smith conceived stratigraphy in 3D but endeavoured to represent his concept in 2D on his remarkable 1815 map, A delineation of the strata of England and Wales, with part of Scotland. Almost two hundred years later his original maps and sections have been digitized and combined with remote sensing data. ...

Earth Science for Disaster Risk Reduction
With dense urban populations located in one of the most active tectonic belts in the world, Indonesia is a hotspot for natural hazard risk. During the twentieth century, Indonesia had limited means to keep natural disaster fatalities from rising commensurately with the explosive growth in population. This situation is changing rapidly, however, with major political and economic advances over the ...
