 It is located at 21.9° South Latitude, 181.6° West Longitude, and is 21 kilometers across.Images taken by "Cassini" during its March and July 2005 flybys of Enceladus revealed a great deal about the geology of this impact crater.Since formation, Zumurrud has been modified by viscous relaxation (forming an updomed floor like those seen in similar-sized craters on Enceladus, like Shahrazad), tectonic fracturing 
along the crater's rim, forming canyons hundreds of meters deep, and subsequent cratering, like the small crater along Zumurrud's western rim.
