No the New Madrid Earthquake just rang the liberty bell. The earthquake's epicenter was in the boot heel of Missouri, but the earthquake was so strong that it was felt as far away as New York, Canada, and Washington D.C.
The crack stays there.
Yes, an in ground pool can crack during an earthquake if it is close enough to the earthquake.
i think so because if a earthquake is close to a volcano the the shaking from a earthquake will put a crack in the volcano lava chamber and then the volcano erupt.
A large crack in the ground is called a fault which is caused by and earthquake.
A previously unknown fault activated. Alarmingly so, for ground acceleration exceeded 2g in some sites! Have a crack at Christchurch Earthquake in wikipedia, which has a good summary of events.

A large crack in the Earth, formed by a river or an earthquake, would be called a canyon, such as the Grand Canyon, formed by the Colorado River. A smaller crack might be called a fissure.
It may possibly crack.
