Interferometric synthetic aperture radar data from 2020 for landslides at Barry Arm Fjord, Alaska
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. Here, we present the interferometric results of tasked RADARSAT-2 satellite synthetic aperture radar data. Data were acquired from two ultrafine beam modes, U19 and U15, that are acquired over the landslide every 24-days, beginning on May 26, 2020 and June 2, 2020, respectively.
