Earthquake

At low intensity (up to 5 points on the modified scale, Mercalli) may not be too strong with the damage and impact and be perceived as some random side effect:
1 point (imperceptible) — it is noted only with special devices
2 points (very weak) — there is only a very sensitive Pets and some people in the upper floors of buildings
3 points (weak) — there is only inside some buildings, like the shaking of the truck
4 points (moderate) — earthquake noted by many people; perhaps swing Windows and doors;
5 points (quite strong) — hanging objects swing, creaking floors, rattling Windows, crumbling whitewash.

An earthquake in ancient times were called superstitious fear. It was thought that it (or its consequences) predicted some events. For example, in Moscow on 1 October 1445 about six in the morning, when suddenly the ground shook, the building shook and the bells rang by themselves.

Of the same type can be attributed to the effects of shocks due to other causes: passing a random transport, moving floorboards of the old house, etc.

Phenomena: poltergeists, mystic sign, mysterious impact and the like.
