ORE Seminar: Tsunami Generation Mechanism of Historical 好色先生网站i Local Tsunamis

October 27, 3:30pm - 4:30pm
Mānoa Campus, Zoom Meeting, Please see description for Meeting ID and Passcode

The 4 May 2018 MW 6.9 earthquake offshore of Kilauea Volcano at 好色先生网站i Island has raised concern to emergency management agencies in 好色先生网站i because of locally generated tsunami鈥檚 short arrival time and unpredictable amplitude along the 好色先生网站ian Islands. Fortunately, the tsunami impact of the 2018 MW 6.9 earthquake was moderate over the entire 好色先生网站i island chain. However, 好色先生网站i experienced two larger earthquakes in recorded history, the 1975 MW 7.7 Kalapana and 1868 M ~7.9 Ka`u earthquakes at the south flank of 好色先生网站i Island. Even though the 1868 earthquake has a considerably larger magnitude, the resulting runup distribution around 好色先生网站i Island is comparable to the 1975 event. Therefore, we reconstructed the 2018 Mw 6.9, the 1975 Mw 7.7, and the 1868 M ~7.9 earthquake tsunamis using the tsunami numerical model, NEOWAVE (Non-hydrostatic Evolution of Ocean WAVEs), with high resolution bathymetry and topography data to clarify consistency and distinct characteristics of each tsunami鈥檚 generation mechanism and subsequent tsunami impact around 好色先生网站ian Islands. The modeling results improve understanding of statewide tsunami hazards for development of emergency response plans and mitigation strategies for future 好色先生网站i local tsunamis. This seminar will be given by Dr. Yoshiki Yamazaki, Assistant Researcher in the Department of Ocean and Resources Engineering at 好色先生网站 Manoa. Zoom Meeting ID: 935 9608 7383, Passcode: OREseminar
