World analyzes double earthquake… Huge energy released

The American Washington Post newspaper stated in its article that it analyzed the Kahramanmaraş earthquakes, that the energy released rather than the size caused the destruction. According to this, the double earthquake released 30 times the energy of the earthquake that killed 300,000 people in Haiti in 2010.

The destructiveness of the earthquake disaster in TURKEY was the subject of discussion rather than its magnitude. Because some earthquakes of similar magnitude did not affect such a large area and population. The US Geological Survey (USGS) investigated why the earthquake, which caused great destruction in 10 cities of Turkey, affected approximately 15 million people, and was felt in 8 countries, was so devastating.



According to the American Washington Post newspaper, seismic activity and the energy released during the earthquake are as effective as infrastructure problems in the destructiveness of earthquakes. The newspaper reported that recording the magnitude gives scientists an idea of ​​the scale of earthquakes, but that the energy released by these natural events is what makes them deadly. The intensity of earthquakes is measured logarithmically and there is a difference of 10 units between each degree. For example, a magnitude 7.0 earthquake is considered to be 10 times stronger than a magnitude 6.0 earthquake and 100 times stronger than a magnitude 5.0 earthquake. However, the energies released in the earthquake intensify 32 times in each step. Dara Goldberg, a geophysicist at the USGS, said: “Earthquakes of magnitude 4.0 and 4.1 and 7.7 and 7.7.



On the other hand, the Kahramanmaraş-centered earthquake disaster corresponds to 26 percent of the total energy released as a result of earthquakes in the world in the last 365 days. In other words, the earthquakes in Turkey alone enabled one fourth of the underground energies released in a year to be released in one day. This made the earthquake quite destructive. Meanwhile, the energy released by the two earthquakes in Turkey was calculated as even more than the sum of the energy released in all earthquakes recorded in the world in the last 3 months.



released in the earthquake is calculated by scientists in ‘joules’ (joules). In the International System of Units, energy is defined as a unit of measurement derived from the amount of work or heat. Apart from the intensity of the earthquake, it is also used to measure the energy (work-heat) released. – According to the measurement of the USGS, the 7.8 magnitude earthquake in Kahramanmaraş was measured as 30 petajoules. The energy released by the 7.0 magnitude Haiti earthquake in 2010, which killed 300,000 people, was measured as only 2.1 petajoules. – In other words, the 7.8 magnitude earthquake in Turkey corresponds to approximately 15 times the Haiti earthquake in terms of energy released.

– 30 petajoules are strong enough to meet the energy needs of 774 thousand houses for one year.

– The tanks of more than 5 thousand Boeing 747-100B type aircraft can be fully filled with this energy.


San Francisco-based disaster modeling company Temblor, co-founded by Turkish geophysicist Volkan Sevilgen and Stanford University Geophysicist Professor Ross Stein in the USA, announced that after the 7.8 and 7.5 magnitude earthquakes according to the measurements in the USA on February 6, the new Earthquake and mapped stressed faults where aftershocks could occur. Stress calculations showed that the 7.5 magnitude earthquake on the Sürgü and Çardak faults may have been triggered by the 7.8 magnitude earthquake on the East Anatolian Fault 110 km south. In the report written by Shinji Toda from Tohoku University in Japan, it was noted that while mapping the faults where new earthquakes and aftershocks can occur, aftershocks will decrease in number and remain clustered in stress-triggered regions, but their size may not decrease.
