The Michoacán coast is located in a tectonically active margin. This coast is subject to tectonic uplift (Ramirez-Herrera and Urrutia-Fucugauchi, 1999, Ramirez-Herrera et al., 2011). The estimated rate of coastal uplift, based on marine terrace ages, for the neighbor areas in Michoacan-Guerrero coast is ca. 6.6 +/- 2 m/ka (Ramirez-Herrera et al., 2011). We extrapolated this uplift rate to compare with our modeled sea level flooding scenarios at the Colola beach. The scenario for next 100-year indicates a 1.4 m sea level rise, with an estimated uplift rate of 0.6 +/-2 m, i.e. a value considerably lower than the projected sea level rise. In this scenario, even when considering tectonic uplift of this coast, the beach areas where turtles nest are foreseen to be inundated by sea level rise. In the second scenario, in 50 years, 0.5 m sea level rise compared with estimated uplift rates of 0.3 +/-2 m/50 yr, again the sea level rise value is still higher than tectonic uplift. Thus, even in this tectonically active coast, sea level rise scenarios suggest inundation of beach areas where sea-turtles nest.
