Web4: What percentage of earthquakes cause tsunamis? It's a very small percent because you need perfect conditions for a tsunami to occur. You would need for it to happen where the fault causes the earth to be pushing up or pushing down on the water. If you have plates that slide side by side, the quake will not generate a tsunami.
