Evidence of preliminary prognosis of appearance of catastrophic earthquake and strong tsunami in the region of Tarapacá, Chile

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.
