Do other planets experience earthquakes?

Other planets (and moons) don't experience earthquakes quite the same way we do on earth; our quakes are generated by plates, resembling pieces of a jigsaw puzzle, that slide past, collide with or separate from other plates that make up the continents and ocean floor. However, Apollo astronauts did detect "moon quakes" on the moon. The planet Mars has huge volcanoes; for example, Olympus Mons is 70,000' high (and we think Mount Rainier is big!) and also deep canyons...both of which suggest some level of quake activity. Finally, the Jovian moon Europa is covered with cracked ice; that suggests "quakes" generated by the tidal pull of the planet Jupiter. My thanks to University of Washington astronomer Don Brownlee for his guidance!
