In Eruption, one gets to draw new tiles by connecting lava flows to cities. If there is already a tile connected to a city, and it is rotated using a Aftershock card, and the lava is still connected to the city in the same way, can one draw new cards?
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
