sounds like you got air in the line causing bubbling to cavitate inside and vibrate. flip the valve lever on top very slowly and relieve the air may take the loss of a gallon or less of water

dmmcoy1971 is likely right - this may have always happened and you just did not notice it (most people don't spend much "quality time" with their water heaters), or if you are not running "hot" water very often air from the incoming water may have accumulated in the tank - though I would not expect vibration except when "hot"water is being run (including flushing toilets if you have tempered water going to the toilet tanks).


Other possible causes - vibration from furnace or boiler on same foundation or exhaust duct pipes, or if a high-efficiency heater perhaps you shut off the thermostat but the heat pump on top is still running and causing the vibration as it tries to heat the water by itself.


Another possible cause - if you have "instant hot" circulating hot water system, with a recirculation pump which keeps hot water moving in the hot piping all the time, that pump running could easily cause the vibration.


Ditto if you are on a well pump - the surges from that pump running (especially if pumping some air at times due to leaking intake pipe or low water level or a piston-type pump with leaking valves) could also do this.


Also - if water softener is doing its backflush cycle that could cause a vibration in the cold water/cold water piping.
