    Although Tanis and Chicxulub were connected by the remaining Interior Seaway, the massive water waves from the impact area were probably not responsible for the deposits at Tanis. Any water-borne waves would have arrived between 18 and 26 hours later,[2]: p.24  long after the microtektites had already fallen back to earth, and far too late to leave the geological record found at the site. It is not even clear whether the massive waves were able to traverse the entire Interior Seaway.[2]: p.8  Instead, the initial papers on Tanis conclude that much faster earthquake waves, the primary waves travelling through rock at about 5 km/s (11,000 mph),[2]: p.8  probably reached Hell Creek within six minutes, and quickly caused massive water surges known as seiches in the shallow waters close to Tanis.[2]: p.8  Seiche waves often occur shortly after significant earthquakes, even thousands of miles away, and can be sudden and violent. Some recent examples include the 1964 Alaskan earthquake (seiches in Puerto Rico),[20] the 1950 Assam-Tibet earthquake (India/China) (seiches in England and Norway), the 2010 Chile earthquake (seiches in Louisiana). Notably, after the powerful magnitude 9.0 – 9.1 Tōhoku earthquake in 2011, slower secondary waves traveled over 8,000 km (5,000 miles) in less than 30 minutes to cause seiches around 1.5–1.8 m (4.9–5.9 ft) high in Norway.[21][2]: p.8

    The Chicxulub impact is believed to have triggered earthquakes estimated at magnitude 10 – 11.5,[2]: p.8  releasing up to 4000 times the energy of the Tohoku quake.Note 1 Co-author Mark Richards, a professor of earth sciences focusing on dynamic earth crust processes,[22] suggests that the resulting seiche waves would have been approximately 10–100 m (33–328 ft) high in the Western Interior Seaway near Tanis[2]: p.8  and credibly, could have created the 10 – 11 m (33 – 36 feet) high water movements evidenced inland at the site; the time taken by the seismic waves to reach the region and cause earthquakes almost exactly matched the flight time of the microtektites found at the site.[23] This would resolve conflicting evidence that huge water movements had occurred in the Hell Creek region near Tanis much less than an hour after impact, although the first megatsunamis from the impact zone could not have arrived at the site for almost a full day.

    That must have been such a wild sight. 100m tsunamis hitting North Dakota, all of the fish breathing molten rock.






  • Lemmy.World was so close to doing the right thing after instance-that-will-not-be named's admins were calling for the death of LW's admins while spreading rumours and labeling others in such a way that painted them as targets for murder. All of that, mind you, with absoultey no evidence other than specuation and their own cooked-up conspiracies about modlog actions or taking and twisting things wildly out of context to fit their made-up narratives so they had someone to say they 'caught' and should be killed.

    .world was on the precipice of doing the right thing and disaccociating themselves from that psychotic shit show, but silently dropped the issue and carried on as usual after wringing their hands for maybe two weeks.

    Literally the spiderman pointing at spiderman meme. I love how absurd their fixation with us is given that we control over 80% of the mod/admin accounts on Lemmy.world.

    I continue to meet with my uncle regarding Nintendo and Pokemon business, including discussions on new games, secret pokemon, how Yugioh was inspired by me, exclusive merch and my own real life pikachu being bred right now by my uncle's scientists.
