The recurrence interval for major earthquakes in the New Madrid Seismic Zone is generally estimated to be in the range of 500 to 700 years. However, some estimates can vary, suggesting a broader range around 500 to 1200 years. This variability is based on geological studies and historical records of seismic activity in the region. Significant events, like the earthquakes that occurred in 1811 and 1812, inform these estimates. Overall, while 500-700 years is a commonly cited figure, it's important to note that exact estimates can differ due to the complexities of seismic forecasting.
