&quot;According to the team&#x27;s simulation:<p><pre><code> * One hour after impact, the tsunami had spread outside the Gulf of Mexico and into the North Atlantic. * Four hours after impact, the waves had passed through the Central American Seaway and into the Pacific. * Twenty-four hours after impact, the waves had crossed most of the Pacific from the east and most of the Atlantic from the west and entered the Indian Ocean from both sides. * By 48 hours after impact, significant tsunami waves had reached most of the world&#x27;s coastlines.</code></pre>

&quot;This tsunami was strong enough to disturb and erode sediments in ocean basins halfway around the globe, leaving either a gap in the sedimentary records or a jumble of older sediments,&quot; said lead author Molly Range, who conducted the modeling study for a master&#x27;s thesis under U-M physical oceanographer and study co-author Brian Arbic and U-M paleoceanographer and study co-author Ted Moore.&quot;
