Two active landslides at and near the retreating front of Barry Glacier at the head of Barry Arm Fjord in southern Alaska (Figure 1) could generate tsunamis if they failed rapidly and entered the water of the fjord. Landslide A, at the front of the glacier, is the largest, with a total volume estimated at 455 M m3 (Dai et al, 2020). Historical photographs from Barry Arm indicate that Landslide A initiated in the mid twentieth century, but there was a large pulse of movement between 2010 and 2017 when Barry Glacier thinned and retreated from about 1/2 of the toe of Landslide A (Dai et al., 2020). The glacier has continued to retreat since 2017. Interferometric synthetic aperture radar (InSAR) investigations of the...
