The link between volcanoes, active faults, and potential habitats "makes the boulder data we have collected so intriguing," said Gerald Roberts, a geophysicist at the University of London who led the British-Italian team that conducted the study, in a prepared statement.
"This is consistent with the hypothesis that boulders had been mobilized by ground-shaking, and that the severity of the ground-shaking decreased away from the epicenters of marsquakes," the study's lead author Gerald Roberts, of the University of London, said in a statement.
