Can a 7.0 earthquake cause a tsunami?

“Earthquakes below 7.5 or 7.0 usually do not trigger tsunamis,” said geophysicist Don Blakeman of the U.S. Geological Survey’s National Earthquake Information Center. “However, sometimes 6.0 earthquakes can trigger local tsunamis, which are smaller and less destructive.”

Can an earthquake split the earth?

Certainly, earthquakes can cause cracks to form in the Earth, such as happened during the Loma Prieta earthquake in 1989.
