Abandoned Apollo 17 lunar lander module caused tremors on the moon

They speculate that the rapid heating of the moon lander (Lunar Module) when the sun hits it, is the cause of some moonquakes. I'm not clear why this would happen, does anyone else get it?

These quakes were detected for a while after Apollo 17 left the moon in the late 1970s. Not clear if this is still happening. If the expansion of the LM can cause a detectable ground quake, what is it doing to the LM structure after so many years?
