Aubreya Adams, a postdoctoral researcher at Washington University in St. Louis, describes the Cameroon Volcanic Line as "one of the most interesting features in Africa that most people have never heard of." These volcanoes are something of a mystery, even to geologists - nobody knows exactly how they were created. However, Adams' research is shedding light on the puzzle. Here she discusses her findings and shares some of the process behind seismology fieldwork.
