14th Munich Earth Skience School

www.berghotel-sudelfeld.de

3 - 8 March, 2024

The special topic will be volcano seismology. As usual the winterschool starts with updates and news on the ObsPy Python library (www.obspy.org). The lecturers will train aspects of volcano seismology including the use of 6C observations (rotations and translations), array methods, tremor analysis, polarization analysis, tilt correction for long-period signals, volcano hazards and early warning methods, source inversion, and others). Participants will have the opportunity to present their own research.

Lecturers: Chris Bean (DIAS, Ireland), Thomas Lecocq, Raphael de Plaen (ROB Brussels), Joachim Wassermann (LMU Munich), Glenn Thompson (USF, Florida), Eva Eibl (Univ. Potsdam, Germany), Felix Bernauer, Fabian Lindner (LMU Munich), Adam Ringler (USGS, Albuquerque)

Organization and contact: Heiner Igel (LMU Munich) and Thomas Lecocq (ROB Brussels).

Costs: 750 € (incl. 5 days accomodation and half pension - breakfast and dinner, three coffee breaks per day, conference facilities, tuition, software). Arrival Sunday afternoon March 3 leaving Fri March 8 (lunch time). Note that the costs do not cover: lunch, drinks during meals, winter sport facilities. The number of participants is limited to ~40. First come, first serve basis. The area can be reached by train from Munich Airport (terminal station: Bayrischzell). Please note that there are only a few single rooms. You are encouraged to (or might be forced to) sharing a double room.

Practical information: Lectures, practicals will be given from 8-11 and after 3pm (open end). Between 11am and 3pm (depending on conditions) winter sports facilities can be used (www.sudelfeld.de). More info on the winter sport program can be found here.

Philosophy: This workshop combines the thrill of learning, studying, and practicing seismology and new methodologies, with the thrill of wintersports and being out in nature. Beware that the hotel is isolated in the mountains, no shopping, little to no public transport to anywhere. WLAN is available free of charge at the hotel. Note that we provide half pension only, in the ski area (within walking distance) there are restaurants where lunch is available.
