Landslides in the Sedongpu gully on the Tibetan Plateau
The Landslide Blog is written by Dave Petley, who is widely recognized as a world leader in the study and management of landslides. One of the most landslide-prone locations on the planet is the catchment known as the Sedongpu gully, which is located on the Tibetan Plateau. Located at [29.8009, 94.92014], this is an area […]

Seismologie: Ein vielversprechender Weg zur Überwachung von Permafrost
Passive seismische Daten von einer Messstation auf der Zugspitze zeichneten im Lauf der letzten 15 Jahre den Schwund von Permafrost auf. Somit eignet sich dieses Verfahren vermutlich auch für die langfristige Überwachung der Umwelt.
