Seismographs were originally designed to measure the strength of tremors. But, as it turned out, they can be used to measure the level of various fluctuations, such as the roar of fans in the stadium or the explosions of ammunition.
Military specialists became interested in the new capabilities of seismographs, who learned with their help, by the nature of the detonation, to determine the type of ammunition or weapon. And a new direction appeared in forensic science - forensic seismology.
In a new study, seismologists talked about how they were able to use a conventional seismograph to identify munitions that exploded at one of the arsenals in Baghdad in 2006.
One of the co-authors of the article, Michael Vissession, and his Iraqi counterpart, Gassan Alekabi, collected and systematized data from the hard drive of a seismograph located near the ammunition depot.
Comparing the data obtained with the records and eyewitness accounts, it was possible to find out that the cause of the explosion at the warehouse was a mortar attack and the detonation of two mined cars. The seismograph was even able to record the flight of the helicopter over the scene.
Scientists are confident that such an analysis will help special services in the future to accurately and quickly determine the place and cause of large explosions and prevent possible terrorist attacks.
