The researchers studied images captured by the MRO satellite’s HiRISE camera and found that the “rock-ejection barriers” were concentrated in one place, suggesting that this does not happen by chance.

Mars It has seismic activity, scientists from India suggest based on the traces left by rocks on the Red Planet.
The team of Dr. S. Vijayan, a scientist at the Physical Research Laboratory in Ahmedabad, India, has analyzed in detail thousands of images of the equatorial region of Mars taken between 2006 and 2020 by the HiRISE camera, aboard the MRO satellite, mentioned Saturday (22) The New York Times. The results of the study were published In Geophysical Research Letters Revista.
Vijayan reported that scientists were able to find about 4,500 tracks of rolling rocks, which also Show changes in direction, and the repercussions that may result from rocks crumble The piece keeps sliding down.

However, the “ejected rock fall,” as scientists call it, can only be seen for four to eight years, which they suggest is caused by winds erasing the ejected rock and redistributing Martian dust and sand.

Thus, this phenomenon will be evidence of seismic activity on Mars due to About 30% of the rocky bands It was centered in the Cerberus Fossae region, although it made up only 1% of the study area.

“These massive blocks of dense rock are loaded onto the surface Creating tensions across the surrounding Martian crustDr. Alfred McQueen, a planetary geologist at the University of Arizona in the USA, and a principal scientist at HiRISE, was not involved in the research.
