Tectonic activity occurs on the cracks of the Earth, they are cracked by earthquakes. Imagine this, take all the land masses/oceans on the face of the Earth off of it, and imagine all the locations of earthquakes pinpointed on the "bald Earth". I f you connect those dots you get the tectonic plates which are constantly moving, just so slow we cannot recognize it. There are 7-8 main tectonic plates depending on how you classify…
Earthquakes on Mars are simply known as earthquakes, just like on Earth. Note there is no such thing as a "Marsquake" as some people state. An earthquake is named so because the earth (the ground beneath us) is quaking, not the Earth (our planet). The same thing applies to Mars - earthquakes on Mars are not in any way known as "Marsquakes".
