These earthquakes can sometimes occur more than once, not just once. These great earthquakes, which scientists put on the agenda at every opportunity and warn us, and of which we have seen many examples in our country over the years, in very short time intervals can occur.

The succession of two major earthquakes in Kahramanmaraş in recent days raises this question even more. Major earthquakes, why is that One after another and the underlying cause of these massive earthquakes possible cause Why?

A magnitude 7.8 earthquake in Erzincan in 1939 started the largest series of dominoes the world had ever seen.

This domino effect shattered the series of 12 major earthquakes that occurred on the North Anatolian Fault over 60 years for 1,000 km from one end to the other. In its simplest form, this an earthquake that constantly triggers the next earthquake.

More precisely, the domino effect can be defined as the earthquake’s ability to affect nearby faults when a problem occurs on a given surface.

Starting from the question of how long earthquakes on a surface would spread, scientists at the University of Nevada looked at 22 earthquakes that happened around the world, including in Japan, New Zealand and California. Researchers have identified each of these earthquakes as one mistake slipped against another confirmed the cause.

Complex areas with overlapping fault segments, such as those of California’s San Andreas Fault System. how long an outbreak can last make measurements difficult.

The Kahramanmaraş disaster, which caused the destruction of thousands of buildings and the death of about 40,000 people in Turkey, is one of the earthquakes caused by the domino effect that started with the Erzincan earthquake.

In addition to this domino effect, there is a shallow earthquake that can be called as shallow at 8.6 km in the first earthquake and 7 km in the second earthquake, which makes the surface movements more intense. fault fracture state why.

While experts state that the first magnitude 7.7 earthquake released 32 times more energy than the second, and because the earthquake scale is logarithmic, a magnitude 7 earthquake is, 0 stronger than a magnitude 6.0 earthquake. 10 times bigger manifests itself in intensity.

While seismologist Ross Stein argues that Turkey is close to a tectonic vice, he adds that Turkey is moving north from the Arabian Peninsula and has been pushed in that direction towards the solid border of northern Europe. In short, Turkey squeeze to the west.

Due to the domino sequence formed along the North Anatolian fault line, the earthquakes in central Kahramanmaraş may not have ended yet.

Earthquakes interact through stress currents, and this is kind of chain reaction It means. An earthquake can reduce the stress in the broken parts, but this stress is transferred to the other parts.

The aftershocks rising in this direction, on the other hand, follow this logic completely. Aftershocks don’t just occur in fractured areas. At quite great distances around that area can also occur.

Scientists didn’t think strong earthquakes would trigger tremors in remote areas. Until 1992, when we discovered that the 7.3-magnitude Landers earthquake was causing earthquakes in a remote area like Yellowstone National Park.

Scientists who have begun to do more research on the subject have begun to look at the earthquakes of magnitude 7 and larger that have occurred since 1990, including the 2004 Indian Ocean and the 1999 Izmit earthquake in Turkey. 15 major earthquakes analysed.

Researchers examined the sounds in the regions 5 hours before and after these earthquakes, and 12 of these large earthquakes triggered earthquakes in different parts of the world. causes surface waves Has detected.

For example, the 2004 Indian Ocean earthquake produced small earthquakes in remote places such as Ecuador, Alaska and California. In summary, researchers have found that surface waves from large earthquakes usually occur Can produce earthquakes of 4 or less came to its conclusion.

Opinions are that the magnitude 9.3 earthquake that struck China in 2008 could trigger other earthquakes around the world.

While studies confirm that large earthquakes can affect many different parts of the world, regions not prone to earthquakes. shows that it can even routinely encounter minor shocks.
