How do earthquakes generate tsunamis?
•Panel 1—Initiation:
•
•
•
•
•
•
• the earthquake rupture occurred at the base of the continental slope in relatively deep water or beneath the continental shelf in much shallower water  
•Panel 2—Split:
•
•
•
•
•
•Within several minutes, the initial tsunami is split into a distant tsunami and a local tsunami;
•The height above mean sea level of the two oppositely traveling tsunamis is about half that of the original tsunami .
