Actually 3 Earthquakes In Kahramanmaraş, Not 2

A few days ago, ITU Mining and Geological Engineering lecturer prof. Dr. Cenk YaltırakIn an interview he gave, he stated that there are 4 risky fault lines instead of 1 in Istanbul and that the earthquake expected in 2026 may be much larger than expected.

In addition to this statement, Yaltırak presented the data on which we rely on earthquake risk in our country. because it is not reliable also mentioned. The most striking of these was that, with the effect of the agenda, 2 earthquakes were reported instead of 3 earthquakes.

But if everyone proceeds in the light of concrete data, how do different results emerge?

According to Yaltırak, the first earthquake centered in Kahramanmaraş with a magnitude of 7.7 was actually from the combination of two earthquakes is formed. In other words, this situation emerged when two faults broke at the same time.

occurred later 7.6 magnitude With the earthquake, the fact that there were actually 3 earthquakes emerges. In order to be able to detect earthquakes that occurred at the same time, Yaltirak said, they must be extremely sensitive. measuring ground motion You have to look at the devices.

In addition to these, the Kandilli Observatory twitter In the statement he made on February 6, 2023 at 04:17, the 7.7 magnitude earthquake that took place in Kahramanmaraş. It occurred with 3 different shocks. and confirmed that the earthquake lasted longer than 80 seconds. Also, in a statement “The earthquake broke out on both sides (NE-SW), with a single piece in the south and two pieces in the NE-direction, with a total earthquake of Mw=7.7. In short, multiple refraction analysis is a scientific statement, does not change the fact that the earthquake was Mw=7.7.Using the statements, the officials stated that there was no mistake in the calculations.

A similar situation was seen in the 1999 earthquake.

In other words, according to Yaltırak’s words, the severity in 1999 was 7.4 by the Kandilli Observatory and by the USGS. 7.6 In the earthquake determined as 3 earthquakes intertwined was in question.

The first of these was 6.9, the other 7.0, and the last 7.4; but the first two, the value of 7.4 overshadowed. We can say that this explains why the US Geological Survey (USGS) achieved a higher value.

So how does this happen?

According to Yaltırak’s statements In the 1999 earthquake The resulting 7.4 severity was caused by the simultaneous rupture of two faults. The same is true for the first earthquake in Kahramanmaraş. Because the earthquake, which was announced by the Kandilli Observatory with a magnitude of 7.7, with the breaking of two faults 7.7 magnitude has revealed.

So why is this important?

According to this information, the earthquakes we expect -which is now on the agenda after Kahramanmaraş, Istanbul- may go far beyond the expected intensity and cause greater destruction.

The reason for this again lies in Yaltırak’s statements. According to his own studies to a false danger map We look at the map, and according to the more consistent map in question, it is also possible during the Marmara earthquake. multiple faults it will break.

This is both during the Marmara earthquake, where a great destruction is already expected. greater violence will cause the release of inconsistent hazard map Because of this, many structures that were thought to be safe will suffer great damage.
