The Most Remote Spot in Alaska | Geophysical Institute
2024年12月19日 · Dissing uses a GIS program with a blank map of Alaska to which she can add features, such as rivers, towns, roads, and trails. To begin the search for Alaska’s middle-of-nowhere, she created a buffer zone of increasing mileage around Alaska roads, trails, and villages. The most remote spots appeared as tiny wedges in northwest and northeast ...

2024年12月19日 · Over extended periods of time, the accumulated offset becomes substantial. On the basis of comparing similar rock types on both sides of the Denali fault in Canada and Alaska, scientists at the Geophysical Institute estimate that 240 miles (400 kilometers) of displacement has taken place over the past 60 million years.
New tsunami map tool empowers Alaskans to plan for the worst
The new Alaska Tsunami Hazard Map Tool makes this information easier to access, especially for rural communities with limited internet connectivity. “This is why I came to Alaska: to make something that actually helps people living in the danger zone,” said Elena Suleimani, a senior tsunami scientist with the project, who came to Alaska ...
