Receding Ocean Levels
While normal tide changes can be drastic and no cause for alarm, especially during specific moon cycles, if it looks like a beach has doubled in size, and the water looks like it’s being sucked in by a giant vacuum, get out of there. This is one of the only telltale signs of a tsunami or tidal wave that can absolutely devastate coastal towns that don’t have the proper infrastructure to deal with this kind of issue. Unfortunately, tsunami prevention isn’t something that’s typically covered by insurance providers, so you should grab your loved ones and get as far away as you can, forgetting about the material possessions that you left behind.
