The Avro RJ85 crashed due to electro-magnetic pulse (EMP), endured as it crossed over the plate border between the S American Plate and the North Andes Plate. Some assign the North Andes Plate to the S American Plate, and others assign it to the Caribbean Plate, as it has rock attachments to both. Though this region has not had heavy EMP before, the S American Roll is on the move, with an aggressive uptick. Pilots would be wise to avoid this plate border if possible, as it is subject to pressure from more than one source, and thus is likely to be under almost constant EMP in the future.
