I got datasets about Tsunami events.

According to International Tsunami Information Center and Indian Ocean UNESCO Tsunami center, for an earthquake to cause Tsunami it should have a large magnitude (> 6.5) and shallow focal depth ( < 100 km ).

But there are entries in NOAA tsunami dataset with focal depth of 260 km and a magnitude of 6.8 occurred at sea with the epicenter located at 21.1 km from the nearest coast. There are also entries with magnitude range of 4-5 causing tsunamis.

Are there some other characteristics of earthquake that may cause tsunami?
