Below, a detail of the slide at upper left in the image above shows particular details of the type of failure that inspired the unusual “blowout” name: a curved failure surface and arcuate scar, no erosive track, no intact slide block, and debris spread as a sheet over the slope below.

Linked below is a full-length post I recently wrote about these slides on the Appalachian Landslide Consultants, PLLC, page, which shows blowouts related to atypical storms in several Appalachian settings:
