Parts of the town of Wetumpka, Ala., sit within a 4.7-mile in diameter meteor crater. ... an atmospheric blast wave and falling debris that would have reached to what is now the Gulf of Mexico.
To form a Gulf-size crater in rocky soil, the energy required is 14 trillion megatons. If we assume an impact speed of 45,000 mph (72,000 km/h), the culprit body must be about 51 miles (82 km) across.
The colossal impact event, which triggered a mass extinction event over much of Earth's land and ocean environments, also filled the present-day Gulf of Mexico with nutrients for at least 700,000 ...
