As nouns the difference between focus and center is that focus is (countable|optics) a point at which reflected or refracted rays of light converge while center is the point in the interior of a circle or sphere that is equidistant from all points on the circumference. Measuring exercise intensity using the exertion rating scale. 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. Lift the weight for 1 second and lower the weight for 3-4 seconds. Epicenter is the location on the surface of the Earth directly above where the earthquake starts.

MLA 8 As a verb focus is to cause (rays of light, etc) to converge at a single point. When you say an earthquake, this means that the intensity of the movement is going to be strong. When the stations are far from the earthquake focus, or the earthquake is shallow, the difference between the distance to the focus and epicenter is ignored. A hypocenter (or hypocentre) (from Ancient Greek: ὑπόκεντρον [hypόkentron] for 'below the center') is the point of origin of an earthquake or a subsurface nuclear explosion.In seismology, it is a synonym of the focus. Because of the refraction that takes place at the CMB, waves that travel through the core are bent away from the surface, and this creates a P wave shadow zone on either side, from 103° to 150°. S waves are more dangerous than P waves because they have greater amplitude and produce vertical and horizontal motion of the ground surface.

Aerobic activity, also known as cardio or endurance activity, is the cornerstone of most fitness training programs. writer, Check the Explanation: Answer from: gisellekatherine1. The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures. The terms seismograph and seismometer are often used interchangeably; however, whereas both devices may detect and measure seismic waves, only a seismograph possesses the capacity to record the phenomena. The Focus is pretty much where the earthquake starts but some people say it is the center of the earthquake. Using an earthquake recording station, learn how to determine the distance between the station and an earthquake based on the time difference between the arrival of the primary and secondary seismic waves. 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.
