Answer 1

The U.S. Geological Survey has forecasted a 25% chance of a magnitude 7.0 earthquake occurring in the New Madrid, Missouri area within the next 50 years. The region is known for its history of large earthquakes, so preparedness is crucial.

Step-by-step explanation:

The evidence obtained from paleoseismologic analysis of trenches cut across faults and folds in the New Madrid, Missouri, area has led the U.S. Geological Survey to forecast a 25% chance of a magnitude 7.0 earthquake occurring here within the next 50 years. The New Madrid seismic zone is known for its history of large earthquakes, including a series of powerful quakes in 1811 and 1812. Therefore, it is important for residents and authorities in the area to be prepared for the possibility of future earthquakes.
