Real-time earthquake detection using a submarine DAS array in Monterey Bay, California
LEVERAGING DISTRIBUTED ACOUSTIC SENSING IN MODERN MONITORING APPLICATIONS II ORAL
seismology | 15 december 2023
Yuancong Gou, Richard M. Allen, Weiqiang Zhu, Li-W...
Seismic networks are mostly limited to onshore sensors. Application of DAS to submarine cables has the potential to extend the reach of seismic networ...

SEISMIC ANISOTROPY AND MANTLE DYNAMICS: OBSERVATIONS, MODELS, AND EXPERIMENTS I ORAL
study of earth's deep interior | 14 december 2023
Dorian Soergel, Utpal Kumar, Barbara A. Romanowicz
The presence of ponding slabs at the base of the mantle transition zone (600-700 km) has been well known for a long time and can be explained by the c...
