The Charlevoix Seismic Zone (CSZ) is the most seismically active region of eastern
Canada. Earthquakes of magnitude 6.0 and over occur once every 52.4 years on average.
The last one occurred in 1925. Let us assume that earthquakes occur independently
of each other and so follow a Poisson distribution.
QUESTIONS:
1. What was the probability of one large quake (magnitude 6.0 and over) in CSZ during the next 10 years for someone living in 1926?
2. What is the probability for someone living today?
3. Explain how your answers to Questions 1 and 2 compare to each other.
