Cause of Aftershocks Even 1-2 Years After Earthquakes

After two major earthquakes affecting 10 of our cities, according to AFAD’s data, approximately 2 thousand 724 aftershocks happened. As the aftershocks continue, people are wondering how long it will last. The answer is unfortunately not very positive.

aftershocks, ground shaking These are small earthquakes that occur after the pioneer earthquakes in the regions where the earthquake is located, do not exceed the main earthquake, and decrease in size over time.

Earthquakes come in clusters. The largest in any earthquake cluster is called the main shock; those before it are pre-concussions, and those after it is an aftershock.

When an earthquake occurs, the rock from the sudden break Some of the released energy is transferred to nearby rocks, increasing the pushing, pulling and bending stresses already present on them.

When these tensions are too great for the rocks to bear, they too breaksreleases a new cycle of suppressed energy and creates new faults in the rock. In this way, earthquakes cause aftershocks, and aftershocks produce smaller and smaller aftershocks.

An earthquake large enough to cause damage will likely produce several aftershocks felt within the first hour. Aftershocks speed decreases rapidly. from the main shock the number of aftershocks on the next day, about half of the first day as much. Ten days after the main shock, the number of aftershocks drops by a factor of ten. Larger earthquakes have more aftershocks and larger ones.

Also, more than a year or more after a mainshock. small earthquakes As the earthquake may continue to occur, there is a possibility of a large aftershock long after an earthquake.

Aftershocks a certain time there is none. Aftershocks that occur after the earthquake can last for 1 month or can continue for 2 years.

A certain amount of tension is released in every earthquake, but in large earthquakes, the entire voltage is released with a single earthquake. not released and each aftershock more and more releases tension. Therefore, any large earthquake involving a large fault generates many small secondary fractures with its energy; so many aftershocks occur.

Lengths of aftershocks sequence depending on the magnitude of the earthquake. will be. Larger earthquakes have much longer sequences of aftershocks as they activate larger faults. If it is a minor fault, then the frequency of aftershocks will take.

Kandilli Observatory Director prof. Dr. Haluk Ozener, In the statement made after the earthquake, aftershocks can last for weeks, months or even 1 year. He said it will continue.

Bodrum-Kos in 2017 in the earthquake that occurred between 9,000 aftershocks had been recorded. In this earthquake, aftershocks can be expected to reach or even exceed these numbers.
