Earthquake causes monster waves

The asteroid strike shakes the foundations of our planet and makes huge oceans ripple like in a bowl of water. In Tanis, North Dakota – 3000km from the impact zone – waves flood a river estuary, burying animals and plants in mud.

Asteroid makes Earth shake

1 The strike causes an earthquake some 1000 times more powerful than the worst earthquake in modern times. Three waves caused by the earthquake hit Tanis, North Dakota – 3000 km away –

6, 10 and 13 minutes after the strike.

Earthquake produces waves

2 The earthquake causes ‘ripples’ on limited water masses such as inlets and inland seas throughout the world, causing up to 100m-high waves. This occurs in the huge inland sea that stretches across the USA from Texas to North Dakota and Tanis.

Monster waves ravage river banks

3 Tanis is located on a river a few kilometres from the American inland sea, but it is still hit by two 10+-metre-high waves within two hours of the impact. The waves carry shellfish and fish from both sea and river ashore, burying dinosaurs and other terrestrial animals in a thick layer of sand and mud.
