The Great Lakes and the Not-So-Great Tsunamis: Did Someone Forget the Memo?
You might think tsunamis are strictly a salty-water kind of deal, wreaking havoc on sunny beaches and stealing shoes (rude!). But here's the thing: even the freshwater giants of the Great Lakes aren't immune to a good wave. Lake Michigan, in particular, has a bit of a secret life as a surprise wave-maker.
Hold on, a Tsunami on a Lake? You Serious?
Absolutely! These aren't your run-of-the-mill earthquake-triggered monsters, though. Lake Michigan's surprise waves are called meteotsunamis, caused by sudden changes in air pressure from storms rolling across the water. Think of it like a giant seiche (basically a giant sloshing wave) on steroids.
Here's the kicker: These meteotsunamis are actually pretty common. Studies suggest around 106 happen on the Great Lakes every year, though most are small and wouldn't win any wave-of-the-year awards.
When Did Things Get a Little Too Wavey on Lake Michigan?
While most meteotsunamis are chill, a few in Lake Michigan's history have been downright dangerous. Here are a couple of notable soakers:
- 1929: A rogue wave, estimated at a whopping 20 feet, swept people off the beach at Grand Haven, Michigan. Not a great day for sunbathing.
- 1954: A 10-foot wave in Chicago turned a fishing trip into a disaster, washing fishermen right off the pier. Talk about a bad catch!
- 2003: Another meteotsunami, possibly coupled with rip currents, is suspected in the drowning of seven people near Sawyer, Michigan.
These are just a few examples, and there have likely been other surprise waves that haven't made the history books.
FAQ: How to Dodge a Lake Michigan Meteotsunami
While predicting these waves is tricky, here are some quick tips to stay safe:
- How to be a Weather Watcher: Keep an eye on forecasts for strong storms with rapidly changing air pressure.
- Know Before You Go: If there's a storm brewing, it might be best to postpone that lakeside picnic.
- Respect the Water: Stay away from piers, jetties, and low-lying areas during storms.
Remember, even a freshwater wave can pack a punch. So stay informed, be cautious, and hopefully, your next encounter with Lake Michigan will be a peaceful one.
