Seminar: FEMA’s Hazus Tools for Estimating Tsunami and Coastal Flood Losses
ORE ZoomDoug Bausch Director of Data Science, Niyam IT, Fairfax, Virginia dbausch@niyamit.com *Online only* Zoom Meeting Link Meeting ID: 963 5962 3640 Passcode: OREseminar https://hawaii.zoom.us/j/96359623640 The seminar will highlight 3 tools developed by FEMA https://www.fema.gov/flood-maps/products-tools/hazus that enable the estimation of impacts to buildings and economic losses based on tsunami and coastal hazard data. The tools will be demonstrated highlighting the data, methods and results for several Oahu scenarios. Hazus 6.1: Is FEMA’s Hazus platform that supports tsunami, flood, hurricane and earthquake losses in Esri’s ArcMap 10.8.2 platform: https://msc.fema.gov/portal/resources/hazus. The overview will demonstrate a tsunami model case study based on UH provided
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
Experimental and numerical investigation on the runup of leading-depression N-waves

However, modern tsunami records reveal solitary waves to be an inaccurate model for real tsunamis. For example, before the arrival of a tsunami at shore, a significant recession of water is often observed. Solitary waves are incapable of capturing this drawdown phenomenon, and the leading-depression N-waves (LDNs)
