Certainly it is possible. All that is needed is a meteor impact in the Pacific ocean. Depending on the size of the meteor, the reach of the resulting tsunami could be anything from a few meters, to many thousand of kilometers. But don't worry too much - the larger the impact, the less likely it is to occur.

Areas near open seas are probable tsunami areas. Certain extraterrestial or unknown undersea activities (such as nuclear missile tests) can trigger a tsunami. If the activity is near LA, it's possible. But I believe the probability is only about 5 to 15 percent. The guys who have tested their missiles underwater (whoever they are) are now aware of what they can cause. So let's count out underwater missile tests as causes of tsunamis. It's not also possible that a great meteor, asteroid or part of an exploded dead planet or star can hit the LA area every year. Undersea volcanic eruption near LA is a theoretical cause, but the probability is also nil.

I would think so its close to the Pacific Ocean.
