Only recently have geoscientists come to understand how ambient seismic noise is generated and propagated. Dr. Lucia Gualtieri is breaking new ground in the field of seismology and revolutionizing our scientific understanding of what seismic signals generated by events other than earthquakes – often called seismic noise – can tell scientists about events such as hurricanes and landslides. Utilizing rigorous theoretical and mathematical modeling techniques, Dr. Gualtieri has shown that seismic data can be used to probe time-dependent ocean and atmospheric activity and this information can be used to study the patterns of climate over time. In addition, Dr. Gualtieri has developed powerful seismological tools that can remotely analyze and track the properties of ‘mass wasting’ events, like rockfalls or landslides, in almost real time, and can reveal details of the interior structure of the earth.

"Using the background seismic signals generated by phenomena other than earthquakes is a unique way to understand the mutual interaction between the solid Earth and the other Earth systems, like the ocean and the atmosphere, and to study our planet as a whole. Despite the progress of the last decades, the potential of this novel research branch of seismology has just been expressed and exciting years lie ahead of us."
