After two major earthquakes that hit 10 of our cities, according to AFAD data, approx 2 thousand 724 aftershocks happened. As the aftershocks continue, people are wondering how long it will last. Unfortunately, the answer is not very positive.

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

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

When an earthquake occurs, the rock of the sudden break Some of the released energy is transferred to nearby rocks, increasing the push, pull and bending stresses already present.

If these stresses are too great for the rocks to support, they are breaksreleases a new cycle of repressed energy and creates new fractures in the rock. In this way, earthquakes produce aftershocks, and aftershocks produce smaller and smaller aftershocks.

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

Also more than a year or more after a head shock. small earthquakes Since the earthquake can continue to occur, there is a possibility of a large aftershock long after an earthquake.

Aftershocks a certain time there is no. Aftershocks that occur after the earthquake can last 1 month or last 2 years.

Every earthquake releases a certain amount of stress, but with large earthquakes, the entire stress is released with a single earthquake. not published and each aftershock more and more release tension. Therefore, every large earthquake with a large fault generates many small secondary fractures with its energy; there are so many aftershocks.

Aftershock sequence lengths depending on the strength of the earthquake. will be. Larger earthquakes have much longer aftershock sequences because they trigger larger faults. If it is a small mistake, the frequency of aftershocks will increase.

Director of the Kandilli Observatory Prof. Dr. Haluk Özener, In the post-earthquake statement, 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. With this earthquake, aftershocks can be expected to reach or exceed these numbers.
