Marsquakes

Recommendable!

"Since arriving on Mars just over a year ago, InSight has detected 322 marsquakes. They are the first quakes ever detected on Mars, and the first on any body other than Earth or the Moon. Scientists aim to use them to probe the Martian interior, including ... layers of crust, mantle, and core.

Most of the marsquakes are tiny, much smaller than anything that would be felt on Earth. But a couple have been big enough — up to nearly magnitude 4 — for scientists to be able to trace them back to their source."

‘Marsquakes’ reveal red planet’s hidden geology: NASA’s Mars InSight lander has detected more than 300 quakes and traced some back to their source.
