fault

epicenter

seismic center

check

question: 1 of 3 questions

Explanation:

• Locus: In mathematics, it refers to a set of points satisfying a particular condition. Not related to earthquake energy source.
• Fault: A fracture or zone of fractures between two blocks of rock. It's where the earthquake originates (hypocenter is near it), but not the energy - radiating source term in the question.
• Epicenter: The point on the Earth's surface directly above the hypocenter (the point where the earthquake rupture starts). Energy radiates from the hypocenter (near the fault), and the epicenter is the surface - related term often used in general descriptions of where the earthquake's effects are felt most strongly in a sense of surface - based location, and it is a commonly used term for the'source' in a general, accessible description of earthquake energy radiation from a surface - reference point.
• Seismic center: Not a standard, widely - used term in earthquake terminology like 'epicenter'.

Answer:

C. epicenter
