“We have developed the first model to account for how Earth’s surface features and shape would influence the spread of seismic activity following a meteorite impact,” head researcher Matthias Meschede told Newstrack India.
Meschede is a physicist at the University of Munich who has been working on this model through the University’s Student Research Collaborators program.
Meschede’s model takes into account the Earth’s elliptical shape, surface features and ocean depths to predict how seismic waves generated by a meteorite collision might spread through the earth.
Using this model, the team simulated the crash that brought about Mexico’s Chicxulub crater 65 million years ago — a collision that is thought to have caused the extinction of dinosaurs and other life on Earth.
“We can, in principle, now estimate how large a meteorite would have to have been to cause catastrophic events,” Meschede said in a statement.
“Our model can be used to estimate the magnitude and effect of other major impacts in Earth’s past.”
