An earthquake (also known as a quake, tremor, or temblor) is the shaking of the Earth's surface caused by a sudden release of energy in the Earth's lithosphere, which produces seismic waves. Earthquakes vary in intensity, from those that are so mild that they cannot be felt to those that are powerful enough to launch things and people into the air and destroy entire towns. The frequency, kind, and size of earthquakes experienced in a given location are referred to as its seismic activity. Seismicity at a specific location on Earth is defined as the average rate of seismic energy release per unit volume. Non-earthquake seismic rumbling is also referred to as tremor.
The apparent function of cofilin in the creation of dynamic cytoskeleton is that the cofilin which is a central component of actin filament sever protein that binds actin feed during filament severing. For the cell to be able to move, the actin filament must be dynamic so that cofilin gets the ability to sever actin filament to create a dynamic cytoskeleton.
