The tragedy of February 6, which is an undeniable fact that it is a difficult test for us, was met with a great shock not only in Turkey but also abroad. So much so that almost most of the countries that sent humanitarian aid to our country from all over the world did not hesitate to send their rescue teams.
Today’s post-earthquake rescue efforts are no longer without resorting to traditional methods being carried out.
Thanks to the new technologies that have been revealed and the new opportunities they provide, disaster victims are no longer sooner And in safer ways they can be saved (although still very insufficient).
AFAD’s field scanning satellite technologies is one of them.
AFAD uses technologies such as the “Post-Disaster Snapshot Transfer Project” to reconstruct the debris fields. able to analyze in detail and can plan accordingly.
In these technologies where “AYDES – UZAL” and “AYDES – Crowdsource” software are used. object-based image analysis, texture analysis, creation of new two- and three-dimensional maps And aerial photography methods can be used.
integrated with AFAD satellites A few other technologies known to be used are electro-optical satellite technologies and “Synthetic Aperture Radar” (SAR).
A device that almost wraps up the earthquake: Earthquake Simulation Device
This technology, which is known to be used by Israeli rescue teams in recent days, has been used to detect building debris that we cannot understand with the naked eye. How they were before the earthquake It is almost revolutionary in that it can simulate.
The device first scans the wreckage of the already collapsed building and provides clues as to how the building might have collapsed. as realistic as possible create simulations. It is a technology that can make mostly accurate predictions about vital information such as where the earthquake victims are, where tunnels should be drilled from the debris to reach the earthquake victims, and which parts of the debris might be dangerous to intervene in.
When the simulation result matches the real result, the rescue teams dig small tunnels towards the earthquake victims’ locations and enough to maintain their body temperature they send small pocket warmers in addition to food. Thus, before starting the rescue efforts, it is ensured that the body temperature of the earthquake victims will be maintained and the rescue operations continue safely.
A technology that can detect survivors by body temperature: Heat Sensitive Debris Scan Cameras (Thermal Cameras)
By identifying people under the debris These cameras are among the technologies that are prioritized to be used especially in post-earthquake rescue efforts.
Red color and its tones in the camera, body temperature of people and hence vital signs showing. In other words, if the earthquake victims are reflected in red on the camera, it can be understood that they are alive. In this way, when red and its shades are found under the scanned debris, it can be questioned whether the earthquake victims are alive or not, and if they are alive, it can be concluded that an intervention should be made.
- The images were taken at one of our eastern disaster areas.
Our lifeguards in the sky: Unmanned Aerial Vehicles (UAV)
Able to reach places that people cannot reach and unmanned aerial vehicles, which can quickly scan large areas, are a lifesaver for both rescue teams and earthquake victims, as they can save thousands of lives in a short time.
Unmanned aerial vehicles whose main functions are area scanning and debris detection, especially the ones we just mentioned when integrated into heat sensitive cameras tools that make it easy to spot survivors under debris. Generally of china And Israel’s In addition to the drones used by rescue teams, Bayraktar TB2 And Bayraktar Akinci Unmanned aerial vehicles are also known to accompany rescue efforts.
- The footage was taken while a drone sent by China was conducting an area scan.
A device that can detect people from their heart rhythms: Heartbeat Detector (FINDER MK4)
This small device, which works by scanning for the heartbeats of those trapped under the debris, is connected to the heat-sensitive cameras we just mentioned. with a similar logic it’s working.
The device is placed in the area intended to be scanned. low but strong microwave signals and if these signals coincide with their heartbeat or breathing and become irregular, it can be concluded that someone is alive.
This device is also compared to other technologies we mentioned in terms of being able to distinguish the heart and breathing rhythms of humans and animals. more reliable data. able to access.
A technology that can scan beyond walls and is often used in operations: Behind the Wall Radar System (DAR)
Also known as “DAR” for short, this system under the wall It is another sine qua non in terms of determining whether the remaining earthquake survivors are alive or not.
This system taking advantage of ultra-wideband (UGB) signals It allows tracking movements in closed areas and detecting earthquake victims in case they move. One of the most commonly preferred methods during its use is to ask people who are trapped under the debris to wave their hands or act in any other way. If the earthquake victim moves, the rescue team can conclude that someone is alive under the rubble and can initiate rescue efforts.
In addition to their widespread use in disasters, DAR systems have been used in our country until today. counterterrorism And hostage rescue He also took on other critical tasks.
Perfect for scanning debris from detecting breath rhythms: Carbon Dioxide Detectors
This device people’s breathing It helps them to be extracted from the debris by analysis and detection.
Most of our biological activities, including the way we breathe, are triggered by our survival instincts after disasters such as earthquakes. shows large increases. This situation, increase in carbon dioxide emissions and therefore a sign that earthquake victims can be identified in this way.
- The image draws attention to the increase in carbon dioxide emissions after an earthquake in Nepal.
If these technologies are lacking, it would be impossible not to mention the traditional recovery methods and techniques used.
The most well-known of these techniques and the most widely applied in our country, by heavy vehicles such as buckets is to be excavated. After as many large pieces of debris as possible have been scooped up, the remainder of the recovery falls to the experts.
Experts are scanning the wreckage one last time, just in case. Benefits before and during recovery some other techniques and technologies We can list as follows:
- Analysis of narrow sections of debris by adding video recorders to flexible rods.
- Taking advantage of rescue dogs’ enhanced sense of smell.
- When all available technologies, heavy tools and methods are used, hand-glove and digging manually.
