Answer 1

Answer:

Difference between the focus and epicentre of an earthquake?

The point inside the crust where the pressure is released is called the focus . The point on the Earth's surface above the focus is called the epicentre .

earthquakes and aftershocks?​

Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 rupture lengths distance from the mainshock. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue.

Answer 2

The focus is the point within the earth where seismic waves originate; it is centered on the part of the fault that has the greatest movement. The epicenter is on the earth's surface directly above the focus.
