Read the newspaper article.
[speculating,] From what has been written there it sounds like the engine problem, at least in part, was what's known as a surge/compressor stall. That where the airflow through the engine gets disturbed and you get disruption to the combustion process.
Big surges often result in a series of bangs/pops and flames out of the engine intake. They can certainly sound very disturbing and looks spectacular (especially at night) but on a scale of mechanical problems they are more akin to a car backfiring than an engine exploding.
Surges sometime clear all by themselves if they are caused by a temporary disturbance to airflow. OTOH they can be caused by birdstrikes or minor engine damage deep inside the engine, in which case the engine has to be shutdown.
As for the turbulence mentioned - You can get vibration in the event of severe engine failure but looking at the images of the aircraft taxiing in there doesn't appear to be any obvious damage to the engine(s) or airframe...
I wonder if they got unlucky with where they were holding to reduce weight and the turbulence was the good old fashioned "weather" related stuff, rather than anything to do with the engine failure?
