km wide Galileo image of part of Io recorded in November 1996. An enormous
dark lava flow, presumably silicate in composition, occupies the upper left.
The two dark spots in the lower left corner and the one to the right of
the lava flow are volcanic vents that appear hot in the infrared. |

The
smaller lava flow within the box at the lower right is shown below in a
high-resolution view recorded in July 1999. This flow, from a volcanic vent
named Zamama, was not present in Voyager images. It therefore formed some
time between 1979 and 1996. |
