If it happens when you are driving fast (60-70 MPH) it could be that your wheels are out of alignment.
shifted or broken belt in the tires
Failed steering stabilizer shock, loose tie rod, bent steering component, slipped belt in a tire, etc.
What make the steering wheel shake is the tires that need wheel balance.
Worn steering parts, worn suspension parts, tires out of balance, out of alignment,
Tires out of balance, bent wheel, worn suspension or steering parts, bent driveshaft.
Not the steering wheel shake itself, however what is causing the steering wheel shake, can certainly be extremely dangerous and potentially cause you to lose control of the vehicle. **GET IT CHECKED OUT BEFORE THAT HAPPENS**
More than likely a bent rim on a front tire, thats what I was just told when recently purchasing new tires.
