Prior to researching today's prompt I thought tremor was like an earthquake and I thought there was a fat chance I'd get a picture of that. Even though where I live is on a fault and we've had mild earthquakes in the past I was sure one wouldn't occur in time for today.
But a tremor can also be something physical. Wikipedia explains it as an involuntary, somewhat rhythmic, muscle contraction involving different parts of the body - but mostly the hands.
Many things cause tremors, among them alcohol withdrawal and caffeine.
Well in my case it couldn't be the former so it must be the latte.
Zip over to Ziva's and see what's shaking respecting today's prompt.
