the region scientists can accurately predict the time and location of almost all earthquakes Which of the following terms best describes a trembling or shaking of the earth that is?Which of the following terms best describes a trembling or shaking of the earth that is volcanic or seismic in origin? Correct! Earthquakes are excluded by most standard property forms, but coverage for may be added by endorsement to most property policies.
What is an earthquake why it is called as seismic activity?When an earthquake occurs, the violent breaking of rock releases energy that travels through the earth in the form of vibrations called seismic waves. These seismic waves move out from the hypocentre in all directions and when they travel long distance from the hypocentre, they become weaker.
What is earthquake describe?An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.
What does an earthquake originate?The earthquakes originate in tectonic plate boundary. The focus is point inside the earth where the earthquake started, sometimes called the hypocenter, and the point on the surface of the earth directly above the focus is called the epicenter.
