It caused 700 fatalities, and more than 7,000 people were injured. The magnitude and location of it were similar to those of the May 14, 1942, earthquake, relaxing some of the strain accumulation that had built up over more than 74 years. A weak tsunami was detected in four nearby tide gauges. Analysis of the records provides useful information on the earthquake and tsunami. An estimate of 6.5 cm of coseismic subsidence was reported at the Bahia de Caraquez and Manta locations, while no movement was detected at Esmeraldas and La Libertad. The analysis also supports the existence of two major seismic asperities and a weaker one farther south. A tsunami resonance occurred at the Bay of Salinas, the location of La Libertad, even though the bay is very wide. It was fortunate that it was inconsequential, this time, because the incoming wave was substantially dissipated. specialized Tsunami Pedernales Ecuador Earthquake 2016 Tide gauges Resonance EQUATEUR 064 032 144 2 art. 05017004 [8 p.] 2018 0733-950X https://www.documentation.ird.fr/hor/fdi:010072012 10.1061/(asce)ww.1943-5460.0000431 0733-950X [F B010072012] https://www.documentation.ird.fr/hor/fdi:010072012 https://www.documentation.ird.fr/intranet/publi/2018/02/010072012.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-03-05 2023-07-11 fdi:010072012 fre
