We published a new study dealing with paleoseismological work on the Milesi Fault near Athens, Greece. A slip rate was estimated based on GIS work, mapping, and trenching. Four surface-rupturing earthquakes in the last 4-6 ka were found, and we estimate magnitudes of around M6.2. With these input parameters, we developed a seismic hazard scenario that also takes into account site effects. Our results show that the official seismic hazard zonation in Greece, which is based on instrumental and historical records, contradicts geological data. We also show that extension in this region is not only confined to the Southern Evoikos Gulf graben system, but a significant amount of extension is accommodated by active faults closer to Athens. more

Share your results with qgis2leaf2014-04-27 | in Teaching
As we are often use geodata and analyse, store them or visualize them using a GIS we depend somehow on the person on the other side to understand how a GIS functions or how to use the GIS. A webmap- like the well know google maps- is therefore an easy way to communicate your data and results. But creating a webmap is not always a funny thing to do as we are more geoscientists than programmers. QGIS2leaf for QGIS is a great plugin for creating a basic webmap. more
QGIS 2.0 released – watch out ESRI!
Working on spatial data is the key feature of being a geoscientist and a lot of this work is done using ArcGIS from ESRI. QGIS was always an alternative especially looking at the costs of a full ESRI license. But when it comes to “making maps” QGIS was always behind ArcGIS in map formatting and export. The map composer was more or less … ugly and not state of the art. more
