How can I prevent my phone from vibrating when service is lost or re-acquired? I find it annoying when I'm in an area with poor service, that my phone vibrates every 15 seconds to tell me that service has been lost, or re-aquired.  How can I disable this vibration?

I have a Nexus 4 with CyanogenMod 10.1.0 (Android 4.2.2).

EDIT: As noted in the (so far) only answer, I can disable all vibrations.  I may resort to this, but this is not really what I'm looking for. I'd like to continue with vibrations for other notifications, if possible.
Check under settings > sound, there will be an option of vibrate on notification turn that off may be this is the possible solution.
