Tsunamis on Mars?
New research has found further evidence of past tsunamis on Mars along the transition zone between the northern lowlands (where an intermittent ocean might have once existed) and the southern highlands, caused when a bolide crashed into that ocean.
The new research simulated the height of the tsunami waves and their propagation direction, run-up elevation and distance for three potential sea levels and compared these models with the Martian deposits.
The study’s results suggest several potential impact craters, 30 to 50 kilometers (19 to 31 miles) in diameter, as the source of the tsunami events. The largest tsunami waves may have been 300 meters (984 feet) high – nearly as tall as the Eiffel Tower – following the impact, and waves up to 75 meters (246 feet) high – nearly as tall as the Statue of Liberty. The waves ultimately reached the Martian coast, potentially traveling up to 150 kilometers (93 miles) past the shoreline.
Below the fold is a video showing the simulation of one such impact and tsunami.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

The formation of Martian oceans could have been from megafloods and been accompanied by their own “tsunamis”. Does this study differentiate between megafloooding events and impact events?
