A seismologist models earthquake probability and finds that a region has a 2% chance of a magnitude 6+ quake each year. What is the probability that no such quake occurs in 10 years?

**Why the odds of next decade: a seismologist’s quiet reassurance on earthquake risk** Growing interest surrounds natural hazards as climate and urban growth converge. When experts say a region faces only a 2% annual chance of a magnitude 6+ earthquake, it sparks questions: What does that mean for safety over time? Is the risk truly so low — or does it add up in ways we don’t see? A recent model by leading seismologists reveals that the chance of no such quake happens in a single year is 98%. Over a decade, understanding this probability helps people make informed decisions — from insurance choices to emergency planning — without fear or complacency. **How risk shapes long-term planning** A 2% chance each year means that, on average, a damaging quake has roughly a 2 in 100 likelihood in any given year. Translating this to 10 years—urgence and perception shift. Yet, the persistent low probability suggests that the risk remains anchored in a manageable range—far beyond everyday hazards. This modeling approach combines decades of seismic data, fault behavior analysis, and statistical refinement to offer a sober estimate, emphasizing that while risk remains, it is chronic and predictable, not sudden or unpredictable.
