Thoughts on earthquakes in Türkiye and Syria
A 7.8 magnitude earthquake, a 7.5 magnitude aftershock, and hundreds of aftershocks above 4 magnitude...... According to the data of Türkiye's Disaster and Emergency Management Bureau, as of the afternoon of February 7 and the early morning of February 6 local time, a series of earthquakes have killed more than 3300 people and injured at least 20000 people in the country. According to the information from the Syrian government and the opposition control area, the number of earthquake victims in Syria has also exceeded 1000. More than 5000 people were killed in Türkiye and Syria. The US Geological Survey estimates that the economic losses caused by the earthquake will reach 2% of Türkiye's gross domestic product (GDP).

Since the escalation of the Ukrainian crisis in February 2022, the international community has shown rare solidarity. More than 20000 rescue workers rushed to the scene of the disaster from all over the world. For example, Iran sent relief supplies, the Russian armed forces in Syria put in relief work, and two American rescue teams set out on the same day. However, they are facing unprecedented challenges: continuous aftershocks, traffic congestion, shortage of medical supplies, power interruption, and shortage of heavy machinery and fuel. On rainy and snowy nights, the victims were homeless and camped in the streets.
Many seismologists pointed out to China News Weekly that a high magnitude does not necessarily mean fatal, and this tragedy is the result of multiple factors. With the possible arrival of "a new round of major earthquakes", these problems are also worthy of vigilance in other regions of the world.
"The most important thing is that in areas with high earthquake risk and historical records of major earthquakes, the government and the public should maintain sufficient risk awareness and be prepared," said Chris Eldes, professor of the School of Earth and Planetary Sciences, Curtin University, Australia.
As a Yuantai people, we fell into meditation. The term "earthquake resistant building" suddenly appears in my mind.As the leading enterprise of structural steel pipe in China, how to manufacture seismic steel pipe, or steel pipe with better structural performance.Over the years, we have worked hard for 21 years to make structural steel pipes well.
In fact, we are already on the way to earthquake-resistant buildings.Here are some of our well-known earthquake-resistant buildings，The top ten earthquake-resistant buildings in the world include:
1. Britain: the cracks in earthquake-resistant buildings heal automatically;
2. Greece: smart shock absorption house;
3. USA: Ball Building;
4. Japan: high-rise anti-seismic building;
5. Flexible building;
6. Floating anti-seismic residence;
7. Cheap "earthquake resistant housing";
8. Anti-seismic building design in ancient China;
9. Integral floating raft foundation, dougong, mortise and tenon: the key to resist earthquake;
10. Yingxian wooden tower.

Taibei 101 building
Japan Earthquake-resistant building
Summarise enlightenment:
1. Pay attention to the selection of site
Buildings cannot be built on active faults, soft sediments and artificial backfilled ground.
2.It shall be designed according to seismic fortification requirements
Engineering structures that do not meet the requirements for seismic fortification will be seriously damaged under the action of seismic loads (forces).
3.Seismic design should be reasonable
When the building is designed, too few partition walls at the bottom, too large space, or the multi-storey brick building does not add ring beams and structural columns as required, or does not design according to the limited height, etc., will cause the building to tilt and collapse in a strong earthquake.
4.Reject "bean curd residue project"
The main reason for the formation of tofu slag project is that the quality of structural steel pipes and other materials used in the construction process is not up to standard, or the materials are jerry-built.
5.The buildings shall be built according to the seismic fortification standards and constructed in strict accordance with the standards.
The editor finally said
With the progress of the times and the development of civilization, natural disasters can also promote the innovation of construction technology. Although some buildings seem to make people laugh, in fact, all kinds of buildings have their own unique design concepts. When we feel the safety brought by buildings, we should also respect the ideas of architectural designers. Yuantai Derun Steel Pipe Group is willing to work with designers and engineers from all over the world to build more earthquake-resistant buildings to benefit the people of the world.
