Volcanoes Using Seismology To Find Where Is The Magma And How Does It Get To The Surface
Webinars - Detail
Volcanoes: Using Seismology to Find Where is the Magma and How Does it Get to the Surface? Dr. Stephen McNutt, University of South Florida
ABSTRACT
New high quality seismic and geologic data and modern methods produce higher resolution models of the size, shape and location of magma bodies – molten rock under the ground. These models allow new interpretations of precursors; the sequence of events that occurs prior to eruptions as the molten rock and gases ascend to the Earth’s surface. In this webinar, Dr. McNutt will show several examples of precursors for recent eruptions, and show what scientists watch for as they interpret the fascinating variety of signals produced by active volcanoes.
