usually the ground shakes and objects sway back and forth, but in very mild earthquakes you will notice nothing except with a seismograph. severe earthquakes may cause building to collapse, burying you.
No, they can't tell that it is a foreshock until a larger earthquake happens. (The largest main earthquake is called the mainshock)
seismograph is how to measure the intensity the earthquake will be or was.

With earthquakes, you really can't tell when or where they will occur.

The word epicenter is typically heard after an earthquake has occurred. This word refers to the area of first impact by the earthquake, and is used to tell how big the earthquake was.
The ground starts shaking lol
Earthquakes, can happen at any time, so it is impossible to tell whether or not an earthquake is happening at this current moment.
It doesnt tell exactly when an earthquake will hit.
