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.

Terri Cook is an award-winning freelance writer whose career has focused on exploring and explaining the 4.5-billion-year-history of the remarkable planet we live on. Cook, who has an M.S. degree in Earth science from the University of California, Santa Cruz, writes about geology, ecology, and the environment—as well as wine, tea, hiking, and biking—for a diverse group of publications, including Eos, Scientific American, NOVA Next, Science News, and EARTH magazine, as well as Avalon Travel and numerous other travel-related publications. Her reporting has taken her to 25 states and 20 countries scattered across 5 continents, from the depths of the Grand Canyon to the sandy Australian Outback to the mist-shrouded summit of Bali’s Mount Batur. As the coauthor of three popular guidebooks, including Hiking the Grand Canyon’s Geology and Geology Underfoot Along Colorado’s Front Range, Cook gives frequent presentations about geology and science communication. She is the recipient of a 2016 European Geosciences Union Science Journalism Fellowship and is based in beautiful Boulder, Colo.
