Web1 dag geleden · However, a major earthquake range with a magnitude of 7.0 - 7.9 occurs more than once per month throughout the world. Whereas, an earthquake ranges to a great extent with a magnitude of 8.0 or greater or comes about only once a year. Knowing the earthquake frequency is important for engineers as they not only strengthen a building … Earthquakes are caused mostly by rupture of geological faults but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its hypocenter or focus. The epicenter is the point at ground level directly above the hypocenter.
