The University of Bristol invites you to a lecture by Katharine V.Cashman, holder of the AXA Chair on volcanic catastrophes.
This lecture will take place at the School of Chemistry of Bristol University on November 10 at 4 pm.
Basaltic lava flows cover much of the Earth’s surface, as well as the
surfaces of the other terrestrial planets; thus basalt forms the
substrate of many volcanic landscapes (and, often, associated
vineyards). The frequency of lava flow activity both threatens nearby
communities and provides unique opportunities for volcanologists to
study active volcanic processes.
For this reason, two of the earliest volcano observatories were
founded at volcanoes with frequent lava flow activity (Vesuvius, Italy,
in 1841; and Kilauea, Hawaii, in 1912). These dual motivations – hazard
and opportunity – have also made locations of frequent lava flow
activity the focal point for testing and applying new innovations in
volcano monitoring technology, particularly new methods of remote
Professor Cashman will review some of these new techniques and place
their contribution in the context of the challenges associated with
monitoring and predicting lava flow behaviour, which relate not only to
the high temperatures and spatial extents of active flows, but also to
their dramatic changes in physical properties during emplacement (from
liquids with included gas bubbles to dense solids).
Remote sensing observations are also providing us with new
perspectives on the post-emplacement evolution of basaltic landscapes,
including both their unique hydrological characteristics and key
controls on flow revegetation.
