Dear friends and colleagues,
I am more than happy to announce that on last Monday (June 20, 2011) Christoph obtained his doctoral degree from the RWTH Aachen University in Geosciences. Most of you know him as very active person in this forum, as a thoughtful scientist and as a friend. Christoph wrote his thesis on “The Baelo Claudia earthquake problem” by means of geological, geophysical, archaeoseismological and palaeoseismological investigations.
