ORLANDO — America’s entire West Coast has been included in a massive tsunami warning spanning the entire Pacific Ocean after a massive earthquake slammed Japan’s northern coast Friday.

• Active warnings from the Pacific Tsunami Center include Hawaii, California, Oregon, Washington and Alaska.

People in Honolulu’s coastal areas have begun evacuating after authorities sound warning sirens.

The magnitude 8.9 earthquake was the largest ever recorded in Japan.

Its epicenter was about 231 miles from Tokyo, unleashing a 13-foot tsunami that swept boats, cars, buildings and tons of debris miles inland. Officials have reported numerous deaths and major damage.

To put it in perspective, the 2010 earthquake in Haiti was magnitude 7.0.

Having survived the Haiti earthquake, myself, one thing to keep in mind is that there will be several aftershocks afterward.

The quake in Japan was, indeed, followed by a series of aftershocks, including one of magnitude 7.4 about 30 minutes later.
