EAPS Geophysics Seminar: Matt Wei: Overcoming the challenge of detecting slow slip events offshore

Dec 6, 2022 - 10:00 AM EST

Speaker: 

Matt Wei (U. Rhode Island)

Matt Wei, Professor at the University of Rhode Island, presents "Overcoming the challenge of detecting slow slip events offshore" as part of the MIT EAPS Geophysics Seminar.

"Detecting slow slip events offshore, especially in subduction zones, is important for both science (fault mechanics) and society (natural hazard). For the last decade, our ability to do so has improved significantly using seafloor pressure data. However, due to the small signal‐to‐noise ratio and instrument drift, the detection of offshore slow slip events is still very challenging. In this talk, I will cover several projects to overcome this challenge, including using a machine-learning based detector and collaborating with physical oceanographers. I will also discuss a recent deployment of about 50 geodetic instrument offshore in New Zealand."
