Episode 37: How to predict a volcanic eruption

Scientists are getting quite good at predicting where and when lava will erupt around the Kilauea volcano – important for the residents of Hawaii. Kilauea has been very active for the past few months.

In the past seven days, residents in the area around Kilauea have experienced more than 900 earthquakes. For the most part these have been minor tremors, often only showing up on seismographs. The quakes are caused by magma deep inside the volcano moving underground; infiltrating cracks and fissures and occasionally shooting lava into the air in dramatic fashion.

All of this is being very closely watched by Dr Janine Kavanagh. She is a lecturer in Earth, Ocean and Ecological Sciences at the University of Liverpool.
