Artificial Earthquakes on an Active Volcano

GNS Science volcanologists recently set up an experiment to test the seismic velocity of the rocks that make up White Island. Over the last few decades it has been New Zealand’s most active volcano and has produced minor eruptions in recent weeks. (For its present activity status click here.) Velocities of seismic waves through the Earth
