This is the area beneath the Earth's surface where the earthquake begins

• epicenter

• focus

• fault line

• tectonic plate

Answer explanation

The area beneath the Earth's surface where an earthquake begins is referred to as the 'focus'. This is not the 'epicenter', which is the point on the surface above the focus. It's also not the 'fault line' or the 'tectonic plate', which are larger geological structures. So, the correct answer to the question is 'focus'.
