Subaerial landslides at the head of Barry Arm Fjord in southern Alaska could generate tsunamis (if they rapidly failed into the Fjord) and are therefore a potential threat to people, marine interests, and infrastructure throughout the Prince William Sound region. Knowledge of ongoing landslide movement is essential to understanding the threat posed by the landslides. Because of the landslides' remote location, field-based ground monitoring is challenging. Alternatively, periodic acquisition and interferometric processing of satellite-based synthetic aperture radar data provide an accurate means to remotely monitor landslide movement. Interferometric synthetic aperture radar (InSAR) uses two Synthetic Aperture...
The USGS Central Region Energy Team assesses oil and gas resources of the United States. The onshore and State water areas of the United States comprise 71 provinces. Within these provinces, hydrocarbon plays were defined and assessed. Each of these provinces is defined geologically, and most province boundaries are defined by major geologic changes. The province boundaries were drawn on the county lines that most closely followed the natural geologic boundaries.

Caption: Map shows volcanic eruptions in Southern Alaska. Augustine volcano, which is shown in the middle of this map of volcanic eruptions in southern Alaska during the past half century, began erupting early Thursday, March 27, 1986, according to the U.S. Geological Survey. Augustine is the only one of the volcanoes shown on the map that is not on the mainland. It forms a small, uninhabited island of the same name in southern Cook Inlet about 180 miles southwest of Anchorage and 70 miles west of Homer on the Kenai Peninsula. Peulik was the last of the volcanoes to erupt, in 1977, before Thursday's activity by Augustine, which last erupted in 1976. Augustine, which rises to 4,025 feet above seal level, is part...
