Asteroid crater on Earth provides clues about Martian craters

The 15-million-year-old Nördlinger Ries is an asteroid impact crater filled with lake sediments. A research team led by the Göttingen University has now discovered a volcanic ash layer in the crater. In addition, they show that the ground under the crater is sinking in the long-term, which provides important insights about craters on Mars, such as those currently being explored by the NASA Curiosity and Perseverance Rovers. Results were in the Journal of Geophysical Research Planets.
