If geologists detect many small earthquakes in the area near a volcano, what can they infer about the volcano?

Many small earthquakes near a volcano can happen when magma moves underground and cracks surrounding rock. This increased seismic activity may signal that pressure is building and an eruption could be approaching, so the best inference is that the volcano is probably about to erupt. It does not prove an eruption will happen, but it is a warning sign.
