Answer:
Explanation:
Originally, astronomers considered a GMT day to start at noon, while for almost everyone else it started at midnight. To avoid confusion, the name Universal Time was introduced to denote GMT as counted from midnight.
Ten times as much for each
magnitude increase; thus a magnitude 7 is 1000 times more displacement than
magnitude 4. Most earthquakes happen at the edges of a
tectonic plates. A break in earth's crust along which blocks of crust
slide relative to one another is called earthquakes.
The focus of an earthquake is the point below Earth's surface where energy was released.
An earthquake is a sudden release of energy in the Earth's lithosphere that causes seismic waves, which cause the Earth's surface to shake. Earthquakes can range in strength from those that are so small that no one can feel them to those that are so powerful that they uproot entire cities, launch objects and people into the air, and harm vital infrastructure. The frequency, kind, and size of earthquakes experienced over a specific time period are considered to be the seismic activity of an area. The average rate of seismic energy release per unit volume determines the seismicity of a certain area of the Earth.
