Abstract. Are analyzed the catastrophic seismic events near Chilean coast and generated by them tsunami 1 April 2014 to north of Iquique with magnitude 8.2. It is noted that event occurred 1 April 2014 was in fact predicted in work (Mazova and Ramirez 1999), in which there were analyzed all strongest Chilean tsunamigenic earthquakes with sources near the Chilean coast. Analysis of catastrophic earthquakes and tsunamis in given region, localization of source of historical earthquakes and character of generated by them tsunami waves permitted authors in that time to make a conclusion about possibility of repeated catastrophic earthquake and tsunami in near 10–20 years. The events near Iquique and Arica city in April 2014 are in this time period. Thus, the evidences, presented in this work, support preliminary prognosis made by authors in 1999.

The 2014 tsunami off the coast of northern Chile are analyzed, knowing that there have been very destructive pan-oceanic tsunamis in the past, It was also forecast in 1999, this tsunami has been simulated taking into account two movements of the seabed, one as a single block and the second as several blocks, as a result it can be seen that the second way of simulating is closer to the measures recorded by tide gauges, also the spectral analysis allowed knowing the characteristics of the flood.
