How to look inside a volcano

This event has ended.

Earth scientists have the privilege and pleasure of exploring all parts of the world, from poles to tropics, from great heights to ocean depths and even beyond, in their search for the information that addresses important challenges relating to the history of the planet.

In the Voyages of Great Discoveries series, internationally recognised experts in a variety of disciplines will present accounts of their adventures in the field, followed by the joys, tribulations and indeed satisfaction experienced in the laboratory as they make the discoveries that have transformed our science.

For those who are unable to join us in person, most of the lectures will be recorded and can be viewed on the Cardiff Earth Sciences YouTube channel.

Abstract

Volcanoes are hot, loud, and scary, thus we know little of their internal structure or underlying 'plumbing systems', which typically comprise a complex network of dykes and sills. Understanding the processes and products of magma intrusion in the Earth's crust, and the extrusion of this material on its surface, is important, given crustal magmatism can represent a natural hazard. In this talk, I will show how 3D seismic reflection data can illuminate the structure and emplacement mechanics of these 'hot rocks'.

Speaker: Professor Christopher Aiden-Lee Jackson
