I forgot important event.  1178 BC is freedom date for Hebrews. Moses could use the huge eruption and earthquakes for freedom of his people that were slaves of pharaohs. Hebrews could overcame reed-sea (Red-sea is bad translation) before attack tsunami that formed by huge eruption in the Aegean Sea. Persecutor army by  Ramesses III (1187-1156 BC), that was Egypt's Last, Great Pharaoh (almost) died by tsunami.
