The 2017 México Tsunami Record, Numerical Modeling and Threat Assessment in Costa Rica
MetadataShow full item record
An Mw 8.2 earthquake and tsunami occurred off- shore the Pacific coast of Me´xico on 2017-09-08, at 04:49 UTC. Costa Rican tide gauges have registered a total of 21 local, regional and far-field tsunamis. The Quepos gauge registered 12 tsunamis between 1960 and 2014 before it was relocated inside a harbor by late 2014, where it registered two more tsunamis. This paper analyzes the 2017 Me´xico tsunami as recorded by the Quepos gauge. It took 2 h for the tsunami to arrive to Quepos, with a first peak height of 9.35 cm and a maximum amplitude of 18.8 cm occurring about 6 h later. As a decision support tool, this tsunami was modeled for Quepos in real time using ComMIT (Community Model Interface for Tsunami) with the finer grid having a resolu- tion of 1 arcsec (* 30 m). However, the model did not replicate the tsunami record well, probably due to the lack of a finer and more accurate bathymetry. In 2014, the National Tsunami Moni- toring System of Costa Rica (SINAMOT) was created, acting as a national tsunami warning center. The occurrence of the 2017 Me´xico tsunami raised concerns about warning dissemination mechanisms for most coastal communities in Costa Rica, due to its short travel time.

Importancia de la batimetría de las planicies abisales en la propagación de tsunamis transoceánicos Chacon-Barrantes, Silvia (Ciencia y tecnología Vol.25,No.1-2 22-33, 2007)The initial form of a tsunami originated by an homogeneous seismic source consists on a simple wave front. While the tsunami propagates in deep water, this simple form suffers several modifications ...
