A ‘seiche’ wave can outpace a tsunami, and both can be triggered by meteorites and earthquakes
A catastrophic event occurred on Earth 66 million years ago. A huge meteorite struck our planet in what is now Mexico, triggering mass extinctions of the dinosaurs and most other living creatures, writes Earth and Planetary Sciences' Associate Professor Craig O'Neill in The Conversation.
A new paper shows the first recorded victims of this impact were fish and other marine animals, stranded by a wave that left them high and dry in an ancient river in North Dakota, at a site called Tanis.
