a cat 5 hurricane in new orleans vs a cat 5 in florida are 2 different things.
hurricanes can be certain death on islands or shanty towns but easily survived in places with good infrastructure and a decent height above sea level.
volcanoes also vary in intensity, some can be watched by tourists I.E. hawaii while others are cataclysmic and beyond what a hurricane can do I.E. Krakatoa but in a much smaller area usually..
In a scenario where you are 30 miles from the center of the disaster and assuming each is the worst documented version, a volcano trumps the hurricane in deadliness.
final note, look up krakatoa, it's terrifying and might kill again.

at least tourists will enjoy taking selfies with a copy of your remains if you end up like the denizens of Pompeii
