What caused the largest Mars quake ever recorded? We'll find out this week on planetary radio.

I'm Sarah Al Ahmed of the Planetary Society, with more of the human adventure across our solar system and beyond.

NASA's Insight Marslander reached the end of its mission on the Red Planet about a year ago, but the science never stops.

Benjamin Fernando, a postdoctoral fellow at the University of Oxford, joins us this week to talk about the largest

Mars quake recorded by Insight and the international effort that it took to

pinpoint the cause of the quake. Then Bruce Betts, the chief scientist of the

Planetary Society and I will talk about our earthquake experiences

in this week's What's Up?

Apparently, we're the kind of nerds that run for the seismograph the moment we feel the Earth

move under our feet.

Honestly, I have a strange fascination with earthquakes.

I grew up in a town that bordered California's San Andreas Fault, where earthquakes happen all

the time.

Our world's earthquakes are caused mainly by the movement of our planet's tectonic plates.

The Earth's lithosphere, which is the rigid outer layer, is divided into several large and small plates that float on this semi-fluid material beneath them.

The plates are constantly moving, albeit very slowly.

Faults like the one that I grew up next to are fractures in the earth's crust where the plates slide against each other.

Over time, stress builds up along these fault lines, and when it's released it causes earthquakes.
