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.”
