What effect would a New Madrid earthquake have on the land itself?
All three measured 8.0 on the ritcher scale, making them the largest American earthquakes ever.
unfortunately yes an 11.0 or higher earthquake could happen tho the earthquake itself would not be the problem the cause of the Earthquake would be the most devastating being caused by either a super Volcano or a large Asteroid hitting the earth. the likely hood of survival anywhere on Earth would be very very slim to none for any type of animal including humans or plant life, although I am sure something would survive Humans…
A Tsunami is an earthquake in the sea. When a tsunami happens it creates a huge wave. The first thing that happened in Japan was the earthquake. The earthquake itself would have been a disaster but then there was a tsunami. Earthquakes are made by the earth's plates were shifting. This shifting may have cause the tsunami as well.
