This CSI method can locate asteroid impact locations on Earth

A team of researchers has discovered how to locate asteroid impact locations on Earth using traditional crime scene investigation methods.


A team of researchers was able to use crime scene investigation methods to identify asteroid Impact sites on the ground. It is very difficult to estimate the number of asteroids that have hit the Earth. The majority of craters have been eroded and eliminated with the evolution of our planet. Over the past billion years, Earth has been hit by asteroids on multiple occasions. Some of them changed the course that history would take.


Sikhote-Alin is the smallest crater-spread landscape on our planet. Formed due to an asteroid collision in the Far East of Russia in 1947. There are numerous examples of such asteroid strikes. In the past 11,650 years, only 30 percent of the Holocene asteroid impact craters have been found. Preparing for this natural danger requires analysis Repeat these small effects in the past and how they affected the environment.

Researchers at University of Exeter They dug trenches in the edges of four pits – Kali Main and Kali 2/8 in Estonia, Morasco in Poland, and Whitecourt in Canada. These asteroid craters developed thousands of years ago on two different continents. By analyzing and comparing the surrounding coal Coal produced by forest firesThe researchers were able to determine the origin of these tiny craters. Dr. Yuri Blado and Dr. Argo Gillet of the Institute of Ecology and Geosciences at the University of Tartu note,“It is surprising that we discovered the same thing at all of these sites: mm to cm sized bits of coal mixed with material expelled during crater formation and located in the same location.”


Determining the impact areas of future asteroids

Dr Anya Luciak, lead author of this study from the Institute of Geosciences, the Polish Academy of Sciences, and the University of Exeter stated,“The characteristics of organisms turned into charcoal reflect the conditions in which they were killed.” The charcoal effect appears to have formed at much lower temperatures than wildfire charcoal, since it lacks the partitions created during direct contact with the flame. Furthermore it, They are all very similar to each other, while in a fire it is common to find heavily charred wood next to branches with minimal damage. “This is certainly not what we expected when we started this study: we think the coal effect was formed when parts of trees that were shattered by impact mixed with local material ejected from the crater,Dr. Luciak said in press release.

Scientists treated coal from asteroid pits as evidence from the crime scene. They discovered that the charcoal was not at all similar to that produced by wildfires. Incoming space debris smashed and tree branches burned. Later, it was combined with dirt and other materials that were excavated from the edges of the pits. This study also It examines the environmental impacts Minor archaeological digs. In the future, we hope that scientists can determine the size and type of large required evacuation area asteroids I headed to Earth a few weeks before the collision.
