| Notes | In this paper, two different scenarios for tsunamis generated after earthquakes are contrasted. Five different sizes of earthquakes are compared. “The immediate objective of this project is to determine how closely tsunami forces at typical coastal bridges compare between the DOGAMI and AECOM (Thio, 2019) tsunami simulations. The long-term objective is to determine the best and most cost-effective approach for estimating the current forces of a 1,000-yr exceedance tsunami for bridge design.” Estimated tsunamis and their effects on coastal bridges are explored, in order to help future bridges be designed to withstand these forces. |
