Seismic Signals
Not so long ago, people living near volcanoes had little that might help them to anticipate an eruption. A deep rumble, a puff of smoke, and ash might foreshadow a major volcanic event. Or a volcano might erupt with no warning at all. This interactive feature illustrates some of the types of seismic activity that may preceed an eruption, which modern seismologists are studying in hopes of improving their ability to predict eruptions.
