Scientists in India suggest seismic activity of Mars based on traces left by rocks on the Red Planet. 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 by the HiRISE camera aboard the MRO satellite, Saturday (22) The New York Times. The results of the study were published in the journal Geophysical Research Letters. Vijayan reported that scientists were able to find about 4,500 tracks of rolling rocks, which also show changes in direction, and branching, which would be the result of rock disintegration and disintegration. Continuation of cutting. However, the “ejected rock fall,” as scientists call it, can only be seen for four to eight years, which they suggest is caused by the erasure of ejected rock traces and the redistribution of dust. This phenomenon would thus be evidence of seismic activity on Mars because about 30% of the rock bands were concentrated in the Cerberus Fosai region, even though they constituted only 1% of the study area. “These massive clumps of dense rock laden on the surface create tensions all over the place,” said Dr. 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.

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.
