Yes. An earthquake may occur in the ocean.
No, they can't tell that it is a foreshock until a larger earthquake happens. (The largest main earthquake is called the mainshock)
to prepare for it and save lives
Aftershocks can occur hours or days after an earthquake.
I do not know but the earth shakes when a earthquake happens...
A tsunami is an ocean wave that is caused by an earthquake. It would occur after an earthquake.
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
