Stephen Arrowsmith

Stephen Arrowsmith is a Professor and Hamilton Chair in Earth Sciences at Southern Methodist University (SMU). His research focuses on seismoacoustics, infrasound propagation, and geophysical monitoring of natural and anthropogenic phenomena. He holds a Ph.D. from the University of Leeds and has contributed significantly to nuclear test monitoring, atmospheric dynamics, and machine learning applications in geophysics.

Key research areas include:

• Integration of seismic and acoustic data for event detection and discrimination
• Analysis of infrasound signals from earthquakes, explosions, and bolide impacts
• Development of automated detection algorithms using machine learning
• Urban seismology and distributed acoustic sensing

Recent work emphasizes multi-modal data fusion, with studies on the Korean Peninsula, Tonga eruptions, and North Korean nuclear explosions. His contributions include advancing global infrasound networks and improving stratospheric atmospheric modeling through infrasound observations.
