Los efectos catastróficos del denominado Fenómeno "El Niño", ocurren a intervalos regulares, teniendo como característica principal: el calentamiento masivo de las aguas oceánicas. El Fenómeno "El Niño" se presenta frente a las costas sudamericanas, pero los cambios están conectados directamente a lo largo de todo el Pacífico Tropical estando ellos relacionados a cambios climáticos globales tanto en la atmósfera como en el océano.

The 2016 Ecuador earthquake (Mw 7.8), is part of the sequence of large earthquakes in Ecuador and Colombia: 1906 (8.4 to 8.8 Mw), 1942 (Mw 7.8), 1958 (Mw 7.7), 1979 (Mw 8.2), all these events with a focal mechanism of the thrust fault type. In this research, we have obtain the seismic source distribution (indicating the presence of 2 main asperities), from inversion of teleseismic signals, as well as the parameters of the seismic rupture process: focal mechanism that indicates a type of inverse fault (strike = 25°, dip = 12°, rake = 118°) for a focal depth of 23 km and the source time function indicating a composite event, the duration of the rupture process was around 70 s, assuming an average rupture velocity of 3.0 km/s. The seismic moment was calculated at 5.74x10{20} Nm, equivalent to a magnitude of Mw 7.8. The smallest asperity is located around the epicenter and the main asperi...
