The eruption wasn't directly linked to the removal of the Heart of Lorkhan. It's main cause was the Ministry of Truth (Baar Dau) crashing into Vivec. The Heart did cause it... indirectly: by the removal of the Heart, Vivec became mortal, and so dissappeared. Because he was gone, his power was not there to keep Baar Dau from falling, even though a new system was implicated to keep it up (which failed).
