Tvashtar Catena
Tvashtar Catena is a volcanic region of Jupiter's moon Io. It is a series of paterae, or volcanic craters. It is named after Tvashtri, the Hindu god of blacksmiths. Tvashtar was studied by the Galileo spacecraft over several years. During this time, a 50km long curtain of lava was seen to erupt from one patera, a lake of lava erupted in the largest patera, and finally a plume of gas burst out, rising 385 kilometers above the moon and blanketing areas as far away as 700 kilometers.
