1964 Great Alaska Earthquake "Story Map" Tour
To commemorate the 50th anniversary of the 1964 Great Alaska Earthquake, the largest recorded earthquake in U.S. history and the second-largest earthquake recorded with modern instruments, the U.S. Geological Survey has created an interactive "story map" that tells the story of how a 9.2 magnitude earthquake changed the landscape and lives of people living in Anchorage, Alaska. This "story map" combines maps, historical and present day images, video and more.

Follow Scientists Working in the Arctic to Better Understand the Winter Regime of Arctic lakes
About one-quarter of the lakes on earth are located in the Arctic making them a crucial component of the Arctic system. Arctic lakes release large quantities of carbon dioxide and methane to the atmosphere and absorb up to 35% more solar energy than the surrounding tundra during summer. Benjamin Jones (Research Geographer-ASC-USGS), Christopher Arp (UAF-WERC), Guido Grosse (AWI-Potsdam), and Ned Rozell (UAF-GI) have begun their 1000 mile annual spring snowmachine-based field expedition in northern Alaska where they will be studying some of the thousands of lakes in the region. Their journey began at Toolik Field Station, about 200 miles north of the Arctic Circle, and will continue on towards the Arctic Ocean. This project will allow researchers to determine the impact of warmer temperatures, changing cloud cover and precipitation patterns, permafrost degradation, and direct human impacts on lakes across Arctic Alaska. You can follow along on the project website blog: http://www.arcticlakes.org/calon-blog.html as well as through Ned Rozell's weekly column in the Alaska Dispatch--Seeking answers in the North Slope's permafrost-thaw lakes and On the North Slope, a research station comes to life for the summer.
How is Climate Change Affecting Migratory Geese in the Arctic?
Every year thousands of black brandt geese migrate to The Arctic Coastal Plain of Alaska where they molt their wing feathers, a process that leaves the birds flightless for three weeks. A recent study by USGS and colleagues from the University of Alaska, Fairbanks and the U.S. Fish and Wildlife Service focuses on how climate change has affected habitat used by the geese. The study found with warming temperatures the flightless geese have shifted from inland lakes to coastal areas where salt marshes provide important habitat offering high quality food and protection from predators for the flightless geese.

USGS Video Commemorates the 1964 Alaskan Earthquake
March 27, 2014 marks the 50th anniversary of the Great Alaskan Earthquake, a magnitude 9.2 earthquake that remains the largest recorded earthquake in US history. Over the last 50 years USGS science has led to a better understanding of mega-thrust earthquakes, subduction zones, the earthquakes they produce, and their associated tsunamis.
