MS Plan A Defense: A Comparative Study of the Tsunamis from the 2021 and 2023 Loyalty Islands Mw 7.7 Thrust-Fault and Normal-Fault Earthquakes
POST 723 1680 East-West Road, HonoluluWilliam Robert Master’s Student Department of Ocean and Resources Engineering University of Hawai’i at Mānoa **This defense will be held both in person (POST 723) and over Zoom** Meeting ID: 940 0074 6297 Passcode: WillMS https://hawaii.zoom.us/j/94000746297 The Vanuatu Subduction Zone is an active tectonic region with a history of moderate to large tsunamigenic earthquakes. While over 40 earthquakes of Mw 7.0 or stronger have occurred along the New Hebrides trench within the past quarter-century, the subduction dynamics, tsunamigenic potential, and coastal risk of tsunamigenic earthquakes emanating from the southern trench remain understudied. We compare the tsunami signals from the 2021
MS Plan B presentation: Resonance patterns along the US west coast from the 2011 Tohoku tsunami
Ryan Braman The 2011 Tohoku earthquake devastated northeast Japan and caused damage and loss of life as far away as the Americas coasts. The pattern of the impact along the US west coast closely resembles those in previous tsunamis originated from different locations. This study seeks to understand the mechanism behind the impact through analysis of non-hydrostatic model results for the tsunami’s propagation across the Pacific and wave action over continental shelves . Recorded data from 13 tide gauges were selected from Washington to California and compared against the computed water surface elevation for model validation. A fast Fourier transform
