Understanding earthquake dynamics: Focus is the origin within Earth; Hanging Wall moves above, Foot Wall remains below; Epicenter is surface point above Focus; Fault Line marks fault movement.
Here are the definitions for each term:
42. Focus (D): The point within the Earth where an earthquake originates. It is the actual location where seismic energy is released.
43. Hanging Wall (B): The block of rock that is positioned above the inclined fault plane. It moves relative to the footwall during faulting.
44. Foot Wall (A): The block of rock that is located below the inclined fault plane. It remains stationary compared to the hanging wall during faulting.
45. Epicenter (C): The point on the Earth's surface directly above the earthquake's focus. It is the location where seismic waves are first felt or detected.
46. Fault Line (E): A line on a rock surface or the ground where movement has occurred along a fault.
These terms are essential in understanding the dynamics and characteristics of earthquakes and faulting processes.
The question probable may be:
What are the definitions of the following terms related to earthquakes and faulting processes: Focus, Hanging Wall, Foot Wall, Epicenter, and Fault Line? How do these terms contribute to our understanding of the dynamics and characteristics of earthquakes?
