Answer: 2
Why: California volcanic eruptions are rare — they happen on time scales of decades-to-millennia, with only a handful of eruptions in the past few hundred to thousand years (for example Lassen Peak in 1914–1917 and Mono–Inyo activity ~several hundred years ago). That recurrence (centuries to millennia at a given volcano, centuries for major regional events) is broadly comparable to the recurrence interval for the largest San Andreas ruptures (which also occur on century-to-millennium time scales on a given fault segment).
By contrast, wildfires occur every year across the state, and tropical/hurricane landfalls on California’s coast are extremely rare.
