Silent vibrations

At 3:15pm, my apartment block shook. The chair I was sitting on vibrated mildly, and then rolled some distance. The carpenters on the floor above, who had been at their work all day, suddenly stopped banging and sawing and drilling and everything went quiet. You couldn't hear it, but the building shook gently. Half an hour later we found out that the earthquake had hit a part of Maharashtra far from here. But I'm wondering, what is far?
