• Tsunami povzroči podmorskipotres, ob katerem pride do

vertikalnega premika. Ob tem

se del energije prenese v

oceansko vodo, ki vzvalovi in tivalovi se z veliko hitrostjo

širijo na vse strani (500–900

km/h). Na odprtem morju ima

val veliko valovno dolžino in

majhno amplitudo (do nekaj

dm) ter periodo od 10 min do 2h. Ko se valovi približajo obali,se valovna dolžina zmanjša,

prav tako hitrost (ok. 20 m/s),

višina pa hitro poveča in nato

silovito plusknejo na obalo ter

povzročijo uničenje.

• Ob potresu 26.12.2004 se je po računalniškem modelu burmanskaplošča premaknila do 20 m proti JZ (v globini 18 km), na površinivertikalni premik do 5 m, horizontalni premik do 11 m. Na levi sliki

vertikalni premiki, na desni sliki horizontalni premiki.

• Do premika plošč je prišlo narazdalji skoraj 1200 km,

količina nakopičene energije je bila tolikšna, da je nastaloveč deset popotresnih

sunkov z magnitudo nad 7.0.• Tu se indijsko-avstralska

plošča podriva podburmansko (povprečno 50mm/leto), na stiku nastal

Sundski globokomorski jarek.
