Deformation waves not associated with earthquakes continuously pass over the surface of the Earth. These are waves with periods of 12, 24 hours and 14 days. Long waves are imperceptible to people, although they have an amplitude 10 times greater than seismic waves. In areas with a thin earth's crust, they usually do not provoke earthquakes (I do not consider mantle earthquakes). If the earth's crust is not subject to geodeformations, then they destroy it. After an earthquake, waves of geodeformation can provoke the collapse of buildings (before the earthquake, these territories were not deformed).
An earthquake occurs when the stress in a certain volume of the medium exceeds its strength limit. As a result, a tear or displacement occurs.An increase in tension can be caused by various reasons.
Why don't you read "the stages of earthquake genesis". They have been recognized by the world's leading experts. If you want to make a discovery, read the basics first.
А почему бы вам не прочитать "этапы генезиса землетрясений". Их приняли ведущие эксперты мира. Если вам хочется сделать открытие, то для начала прочтите азы.
