"That news of an earthquake followed by deceased persons arising did not spread immediately is full proof of a hoax."
I don't think earthquakes were so rare at the time that the Romans would have sent their special correspondents over to Jerusalem. And the evidence for the dead coming back to life would have been - a lot of living people, who claimed they were dead once. You see how it sounds.
It's odd to get hung up on some talking point about why the Romans didn't apparently mention a miraculous event, if they didn't. Most people instinctively - and quite sensibly - dismiss reports of miraculous events unless they experience them first hand. The Church itself automatically assumes reported miracles to be false unless there is excellent evidence. So why would the Romans have been any different?
