Since you asked so nicely, I’ll offer a definition by modifying the Oxford English Dictionary’s definition of pornography. (Square brackets and strikeout are my own)

[Disaster] por·nog·ra·phy | pôrˈnäɡrəfē | noun printed or visual material containing the explicit description or display of [human suffering] sexual organs or activity, intended to stimulate [entertainment] erotic rather than [concern, compassion, or humanitarian assistance] aesthetic or emotional feelings.
