| Zusammenfassung |
| The Reintal is an Alpine valley in the Wetterstein Massif close to the Zugspitze, Germany’s
highest mountain. Due to the variety of active geomorphic processes, including rockfalls off
the steep limestone cliffs, debris flows, and snow avalanches, and the river Partnach, the
Reintal has been the field area of many geomorphological and hydrological research
campaigns over the last few decades.
In 2014, the Geomorphology Section of the GFZ Potsdam started to install a monitoring
network to detect and classify rockfalls in the Reintal. The network includes six seismic
stations, optical and infrared cameras, and two weather stations measuring air and rock
temperature, air pressure and relative humidity, precipitation, wind speed and direction, and
solar radiation. The continuous observations of the network are supplemented by repeated
field campaigns including terrestrial laser scans of a prominent rockfall niche at the
Hochwanner mountain. The about 1,500 m high north face of the Hochwanner experienced
the detachment of a 2.8 Mio m3 rockfall about 500 years ago that created the so-called
Steingerümpel (German for rock debris deposit) and dammed the river Partnach. The cliff
still shows high rockfall activity, and an 80,000 m3 block can be expected to fall in the near
future.
In this contribution, the layout of the observatory and details of the seismic network
centered around the Hochwanner north face are described. Furthermore, the network data of a
severe thunderstorm event in June 2016, that triggered many rockfalls and debris flows in the
Reintal, is presented. |
