Abstract

Tsunamis are natural phenomena that although rarely occurring, clearly affect coastal zones, causing flooding, loss of life, geomorphological modifications of the seabed and the coast, among others. The Colombian Pacific is part of the so-called Belt of Fire within which are the populations of Tumaco and Buenaventura, places where the study will be centered. For the determination of the macro-seismic parameters of each proposed scenario the deterministic and probabilistic approximations were used, and the simulation of events of near, regional and distant origin; was performed using the COMCOT (near and regional event) and MOST (distant event) models. After, a database was obtained with a total of 510 tsunami scenarios for both Tumaco and Buenaventura, from which it is possible to obtain information about the time of arrival and maximum height of the tsunami wave train to the coast. Finally, an expansion of the database is recommended, through a greater densificat
