Explore the hidden structures of volcanoes and their underlying 'hot rocks' through advanced 3D seismic imaging techniques in this 53-minute lecture by Prof Christopher Jackson from Imperial College, London. Delve into the challenges of studying these powerful natural phenomena and learn about the latest geophysical tools used to illuminate their internal structures. Discover how scientists analyze earthquake data, marine acquisitions, and borehole measurements to create detailed models of volcanic systems. Examine case studies from various locations, including Lipan Etna, Katla, and the Southern North Sea, to understand the formation of igneous cells, dikes, and lava flows. Gain insights into the evolution of ancient volcanoes, shield volcanoes, and the interplay between faults and volcanic activity. Conclude with an analysis of South China Sea volcanoes and the broader implications for understanding these geological wonders.
