Fukushima Earthquake (11/3/2011) documentary
Ντοκιμαντέρ του ΣΚΑΪ καταγράφει μέσα από συγκλονιστικές εικόνες τον σεισμό των 9 Ρίχτερ, το τσουνάμι και την πυρηνική καταστροφή στην Φουκουσίμα της Ιαπωνίας. Αυτόπτες μάρτυρες αλλά και επιστήμονες που βίωσαν και μελετούν αντίστοιχα αυτό το σεισμό και τις συνέπειες που προκλήθηκαν στην Ιαπωνία μιλούν στην κάμερα. Τα 9 Ρίχτερ που χτύπησαν την Ιαπωνία την Παρασκευή 11 Μαρτίου 2011 αποτέλεσαν τον πέμπτο μεγαλύτερο σεισμό που έχει καταγραφεί στον κόσμο από το 1900. Το τσουνάμι που ακολούθησε έφερε και τις εφιαλτικές συνέπειες των 10.000 και πλέον νεκρών αλλά και χιλιάδων αγνοουμένων. Ολόκληρες πόλεις χάθηκαν και τίποτα δεν είναι πια ίδιο για τους Ιάπωνες αλλά και ολόκληρο τον κόσμο μετά την καταστροφή που υπέστη το πυρηνικό εργοστάσιο της Φουκουσίμα

ISSARS: New freeware for structure-specific ground motion selection
Current practice enables the design and assessment of structures in earthquake prone areas by performing time history analysis with the use of appropriately selected strong ground motions. This study presents a Matlab-based software environment, which is integrated with a finite element analysis package, and aims to improve the efficiency of earthquake ground motion selection by accounting for the variability of critical structural response quantities. This additional selection criterion, which is tailored to the specific structure studied, leads to more reliable estimates of the mean structural response quantities used in design, while fulfils the criteria already prescribed by the European and US seismic codes and guidelines. To demonstrate the applicability of the software environment developed, an existing irregular, multi-storey, reinforced concrete building is studied for a wide range of seismic scenarios. The results highlight the applicability of the software developed and the benefits of applying a structure-specific criterion in the process of selecting suites of earthquake motions for the seismic design and assessment.
