From the explanation

“Like the downtown area of your favorite city and any self-respecting web site … Io’s surface is constantly under construction . This moon of Jupiter holds the distinction of being the Solar System’s most volcanically active body — its bizarre looking surface continuously formed and reformed by lava flows.”

— APOD editors, August 4, 2013
