Bouncing boulders point to quakes on Mars

"A study of these ephemeral features on Mars, published last month in Geophysical Research Letters, says that such boulder tracks can be used to pinpoint recent seismic activity on the red planet. This new evidence that Mars is a dynamic world runs contrary to the notion that all of the planet’s exciting geology happened much earlier, said Ingrid Daubar, a planetary scientist at Brown University who was not involved in the study. “For a long time, we thought that Mars was this cold, dead planet.”

Now, if one of those big Martian volcanoes would erupt, we'd really have a show to watch.
