M. Jakir Hossen

M. Jakir Hossen will work with Anne Sheehan on tsunami studies using both historic and modern sea-floor and tsunami observation networks. Several initiatives are underway to install offshore earthquake and tsunami monitoring networks at subduction zones that have high potential for megathrust earthquakes. Hossen proposes to apply an adjoint sensitivity method with Green's function based Time Reverse Imaging to identify the optimal sites for deploying new sea-floor sensors in the Cascadia subduction zone offshore Washington and Oregon. Being installed and operated, seismic data can be used for understanding crustal activities and earthquake rupture process. The pressure sensors can provide real-time tsunami data, which can be used to recover a tsunami source model accurately and efficiently. The source model can be used as an input to forecast a reliable near- and far-eld tsunami to reduce the tsunami impact on the coastal communities across the Pacific ocean, particularly, the U.S. territories.
