Those of you who hate earthquakes may want to stop here, because the answer is absolutely, eruptions from volcanoes can cause earthquakes. Multiple earthquakes for one eruption is not uncommon. This is because, as the previous answer stated, the lava and magma erupting up from the volcano can cause the tectonic plates beneath the crust to shift. Shifting tectonic plates that rub against each other cause earthquakes! It’s basic geology, but a lot of us haven’t had basic geology in a long while.
However, since volcanic eruptions can last for hours, it makes sense that there would be multiple earthquakes during a volcanic eruption. So, there’s the long answer to the question. Too long, didn’t read: yes, volcano eruptions can cause earthquakes because they shift the tectonic plates.
