Do you get to draw a card if you rotate a tile?
No, new draws can only be made if a new location is in contact with the lava.

Check the rules on page 6: (emphasis mine)


  If this tile is rotated as shown, only one 
  Action Card is drawn because there is 
  only one lava flow in contact with a new 
  location in the village
