Subsidence cracks getting longer by the day

Thanks all.
Speaking of cracks, what could be causing this beam to rotate and crack the plaster? (I know its hard/impossible to say, but curious. Roof spread?)

Ive got one booked for 3 weeks time.

These cracks are getting wider and longer by the day, and new ones appearing.

But these cracks are only going to get worse.

Are they? A little anecdote that relates to @stevie888 post above.

Many years ago a friend of our family bought a huge house on a hillside sloping down to a river estuary. It was really cheap because it had "severe subsidence", and was being sold as such. My stepfather was an arborist and horticulturist, and the plot this house stood on was bordered by a row of poplar trees all down one side. Stepfather said "cut down the trees", which they did. The house came back up, all the cracks closed and no underpinning was ever done. AFAIK it has been OK ever since. Poplars apparently are one of the worst trees for sucking water out of clay soil.....
