The ocean is going to slosh back and forth in the Pacific for awhile because of Earthquake and Tsunami this large from Chile

It likely won't slosh in as extreme a way as the 2004 tsunami in Indonesia that killed 250,000 people or the Japan Tsunami in 2011 that killed around 30,000 people but still people should be aware that the ocean won't be normal for awhile until it settles down a bit. So, extra caution for anything in the Pacific Ocean especially if  your boat is tied to an anchor or a dock might be important anywhere in the greater pacific basin. It shouldn't affect ships at sea much because it would only raise or lower the height of water various places so at sea most ships wouldn't notice the changes much unless their ships were moved horizontally or in some direction forwards, backwards or sideways, but that shouldn't be enough to affect navigation in most cases.

If you have ever been near a swimming pool in an earthquake it is like that. Once when my youngest daughter was 5 she was swimming on a float in his pool and about a 5.0 hit my cousins place in Orange county California. I jumped up and ran to her at  poolside and told her to stay in the center of the pool so it wouldn't knock her out or otherwise injure her against the edge of the pool. So, I just verbally said, "Stay in the center of the pool. There's an earthquake!"

She just asked, "Why is all the water going out of the pool?" and wasn't really concerned at all. But then she was just 5 and saw it all as mostly interesting and not scary like I did.
