Introducere în cercetarea şi predicţia evenimentelor seismice extreme (Exemplificare – marele cutremur din estul Japoniei)
Introduction to the research and prediction of extreme seismic events (Case Study – The Great East Japan Earthquake)

Summary/Abstract: This article contains preliminary information regard ing the extreme seismic events (ExSeiEv) – complex natural phenomena which could impact with disastrous consequences the society. Focusing on prediction, the article highlights the efforts and the problems which are faced by the scientific community in order to understand the occurrence of the extreme seismic events. Predictions of the extreme seismic events rely on different algorithms developed through statistical and numerical analysis of empirical data. An important task of scientific community is to refine systematically the appropriate models of earthquake occurrences. The basic algorithms of prediction which are usually used by the scientists are presented briefly in article. As well, the extreme seismic events are illustrated by the 2011 East Japan great earthquake which was one of the most destructive events for the mankind. There were approached the problems which occurred in forecasting it. Enhancing the earthquake modeling and forecasting abilities and the accuracy of the information about any possible extreme seismic event, the bottom line is to reduce the costs of the human and mate rial damages. The information provided by the scientists to the authorities have to allow the latter ones a detailed perspective of the measures which have to be taken in the earthquake preparedness strategies and disaster management.
