Tiny fault scarps on Mercury
Images obtained after lowering MESSENGER's altitude have revealed a population of small fault scarps (white arrows) that can be more than an order of magnitude smaller in size than their larger counterparts, like Enterprise Rupes. These small scarps are less than 10 km in length and have only tens of meters of relief. They are comparable in size and morphology to small fault scarps imaged on the Moon by the Lunar Reconnaissance Orbiter, suggesting that these small scarps are relatively young, and raising the possibility that some are even active today!
