U.S. West Coast and Alaska Marine Geohazards

Marine geohazards are sudden and extreme events beneath the ocean that threaten coastal populations. Such underwater hazards include earthquakes, volcanic eruptions, landslides, and tsunamis.

Devastating earthquakes in Japan (2011) and Chile (2010) that spawned pan-oceanic tsunamis sent a sobering reminder that U.S. coastlines are also vulnerable to natural disasters that originate in...

Earthquake Hazards in Southeastern Alaska

Over the last 100 years, the Queen Charlotte-Fairweather fault system has produced large-magnitude earthquakes affecting both Canada and the U.S. To fill in missing details about its offshore location and structure, USGS uses sophisticated techniques to truly understand the fault’s hazard potential.

Tracking Data for Tundra Swans (Cygnus columbianus)

Available here are tracking data of Tundra Swans, a species that nests in coastal areas throughout Alaska and winters across a broad area of North America from the Pacific to Atlantic coasts. These data were collected to better understand the timing and patterns of migratory movements and seasonal use of habitats in breeding, wintering, and migratory areas of North America.
