The point on the earth's surface directly above the earthquake's starting point is called the epicenter, and the point below the earth's surface where the earthquake starts is called the hypocenter or focus. The magnitude of an earthquake is measured on the Richter scale, which ranges from ...

地震波发源的地方,叫做震源(focus)。震源在地面上的垂直投影(vertical projection),即地面上离震源最近的一点称为震中(epicenter)。它是接受振动最早的部位。震中到震源的深度叫做震源深度(hypocentral depth)。通常将震源深度小于60公里的叫浅源地震(shallow-focus earthquake),深度在60公里至300公里的叫中源地震(interm...
What is epicenter and hypocenter? The hypocenter or focus is the point deep in the crust where the earthquake started. The epicenter is the point on the surface directly above the hypocenter where the shaking will be most felt. What are the 4 types of earthquakes? The four types of earthqua...
Because of the large range of this shock, low intensity, slow attenuation and no extreme-earthquake area, its epicenter and focus could not be determined onthe scientific-technological conditions at that time. In the Seismological Catalogue of China (GU, 1983) published in 1983, its epicenter ...
Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the
Epicenter:the point on Earth’s surface directly above the focus of an earthquake. Fault:a break in Earth’s crust where movement of rock occurs. Fault zone:a place along plate boundaries where many faults are located. Focus:the point below Earth’s surface where movement of rock produces an...
An earthquake's point of initial rupture is called its focus or hypocenter. The term epicenter means the point at ground level directly above this. 地震的能量突然释放的结果创造了地震波在地壳中。地震检波器记录,也称为地震仪。地震的矩震级是常规报道,或相关的,大多是过时的里克特震级,3级或低主要是...
An earthquake is caused by sudden slip on a fault which itself described by epicenter, focus, focal depth, after shock, fore shock, magnitude of earthquake, intensity of an earthquake and intensity. Elastic rebound model is a useful guide to how an earthquake may occur. This manuscript reviews...
What is epicenter and hypocenter? The hypocenter or focus is the point deep in the crust where the earthquake started. The epicenter is the point on the surface directly above the hypocenter where the shaking will be most felt. What are the 4 types of earthquakes?
