Today's massive earthquake in Japan released a tsunami wave that, among other things, closed most California beaches and the Great Highway today. As of 8:00 a.m., the Chronicle reports: "The tide began rising shortly after 7:30 a.m. along beaches in Crescent City, where the tsunami was expected to hit the hardest in California. Officials predicted that waves could reach as high as 7 feet."

However, according to AlertSF, "Minimal wave impact is expected."

Still, staying away from the beach today would be your safest bet.
