One of them is that the dry ground and arid vegetation result in little evaporation, allowing most of the sun's energy to be used in warming the air, resulting in increased temperature, which in turn lowers humidity, making it less likely to rain. The other is lack of rain-producing clouds, which allows more sunshine than normal. It s a vibration, on the earth s surface followed by the release of energy in the earth s crust. The earth's crust is made up of giant Plates which are thick slabs of rock that make up the outermost 100 kilometers or so of the earth. Most earthquakes occur only in the outer, brittle portions of these plates, where temperatures in the rock are relatively low.
Many earthquakes occur when the earth's crustal plates grind and shift along one another.
Other earthquakes occur in the middle of the plates and are caused by the geophysical factors. Such factors include, the level of the water table, geological formations including soil and rock deposits over a period of time, or the general stability of the soil and rock in the area. An epicenter is the point on the earth's surface directly above the point inside the earth's mantle that is the focus or the source of the earthquake. Any short-lived, violent atmospheric disturbance characterized by thunder, lightning, gusty surface winds, hail, precipitation,etc constitutes a thunderstorm. It is an event of relatively short duration.
